RECORDS AND DESCRIPTIONS OF NEOTROPICAL
CRANE-FLIES (TIPULID^, DIPTERA). II.
By Charles P. Alexander,
Urbana, III.
The crane j flies discussed in the present article are almost without
exception from South America. They are based largely on collect-
ions made in 1919 near Para, Brazil, by Mr. Herbert S. Parish, the
veteran insect collector of the American Tropics. Several other
interesting species were sent me by Senor Charles Bruch, collected
near La Plata, Argentina, and a few others taken by Dr. Witte in
the Province of Santa Cruz, Southern Patagonia. The types are
preserved in the collection of the writer; paratypes of several Ar-
gentinian species in the Museum at La Plata.

Holotype, J, Quebrada Richa, a branch of the Rio Tapaliza, a
branch of the Rio Puero, altitude 1,300 feet, July 24, 1918 (Axel
Olsson).
This small species is closest to Rhipidia costalis Williston of Cen-
tral America and the Lesser Antilles. In order to supplement Wil-
liston's brief description, which applies equally well to more than
one species in the Neotropical fauna, Mr. W. D. Lang, of the British
Museum of Natural History, has very kindly sent me an enlarged
accurate drawing of the wing of the type specimen of R. costalis.
1 This figure agrees in all the essentials with the fly determined by the
writer as costalis in an earlier paper (Journ. N. Y. Ent. Soc, Vol.
22, pi. 3, fig. 2; 1914), the dark markings along the costal margin
being considerably larger than the pale interspaces, the radial sector
very long, the basal deflection of J? 4t5 comparatively short, basal de-
flection of C«j just beyond the fork of M and other characters. In
Mr. Lang's figures, cell first M„ is shorter and broader than in the
specimen above mentioned, if. costaloides is readily told by the
reduced costal pattern and the venational details.

yellow with large jet black areas, smallest on the propleura ; two large blotches
on the mesopleura, the largest on the mesepisternum, extending from the ster-
num to the dorsopleural membranes; a smaller oval area immediately cephalad

Holotype, J, Igarape-Assu, Para, July 15, 1919 (H. S. Parish).
This curious little fly is referred to the genus Teucholabis with
considerable doubt. The radial cross-vein is completely lacking and
vein Sc 1 is very long for a member of this genus of flies. T. per-
similis bears a great resemblance to T. parishi Alexander (Psyche,
March, 1920.] ALEXANDER : NEOTROPICAL CrANE-FlIES. 7
Vol. 20, pp. 46, 47; 1913) which must likewise be considered a doubt-
ful member of the genus. The present species may be told by the
long antennas and the details of venation, especially the shorter sub-
costa, the lack of a spur of vein i? M and the shorter cell first M 2 with
the longer veins issuing from it. That the spur on J? M in T. parishi
is a normal condition for this species is shown by the fact that it
bears a macrotrichia on this spur in both wings of the unique type,
this undoubtedly representing the origin of vein R 2 .
Genus Gonomyia Meigen.
Gonomyia (Gonomyella) paraensis new species.
Antenna with the basal segments light yellow, the flagellum brown ; head
yellow, silvery pollinose ; mesonotum lead-colored, the lateral margins narrowly
light yellow; wings strongly tinged with brownish yellow, cell i? 2 very short,
cell M 2 very deep.
Male. — Length, about 4 mm.; wing, 4.5 mm.
Female. — Length, 4.5 mm. ; wing, 4.7 mm.
Rostrum and palpi dark brown. Antenna with the first scapal segment
light yellow, stout, moderately elongated ; second segment tumid, dull yellow ;
flagellum slender, brown, the segments with a dense white pubescence, in the
male with long, secund verticils. Head light yellow, darker on the occiput,
covered with a sparse silvery white pollen that is most distinct on the anterior
part of the vertex.
Pronotum yellow medially, the sides dark. Mesonotal prsescutum dark
lead color, sparsely pollinose, the lateral margin narrowly but conspicuously
light yellow, two indistinct brownish stripes occupy the region of the inter-
spaces; remainder of the mesonotum dark plumbeous. Pleura dull yellow,
with a broad, ill-defined, dusky, dorsal stripe. Halteres dark brown. Legs dull
yellow, darkening on the tibiae and tarsi, the latter dark brown. Wings strongly
brownish yellow, the costal region more saturated ; stigma indistinct ; veins
brown, the costal veins more yellowish. Venation : Sc t ending slightly before
the fork of Rs; fusion of R i+S very long, the cell i? 2 being shorter than in any
other described American species of Gonomyella; r at about two fifths the
length of i? a+3 ; cell M 2 very deep; basal deflection of Cu t just beyond the
fork of M.
Abdominal tergites dull yellowish brown, the sternites more yellowish ;
hypopygium dull brownish yellow. In the female the antennas are shorter,
the abdomen dark brown. Ovipositor horn-colored, the tergal valves very long,
slender, upcurved at the tip.

The holotype male has the wings very much darker brown than
in the female, the costal margin being especially suffused; in addi-
tion, the venational details are somewhat different, r being placed
before one third the length of J? M ; R a considerably longer^ slightly
more than one half the length of R 3 ; basal deflection of Cu t some
distance beyond the fork of M. With the exception of these rather
conspicuous alar differences, the two flies are very similar to one
another and until further material becomes available they must be
considered as representing a single variable species.

flies, the three basal segments orange, thence passing into black ; segments four
to nine each bears a single short pectination which is shorter than the seg-
ment that bears it; the last four flagellar segments are greatly elongated,
filiform, their combined length considerably exceeding the remainder of the
antenna. Head yellowish tawny, the vertex very narrow between the large eyes.

brown, this mark widening on the fourth and succeeding segments to include
most of the segments; sternites reddish yellow, segments seven and eight
darker. Hypopygium reddish, the pleurites long, slender, bearing the com-

O. griseipennis Loew. It is characterized by the very short antennal
pectinations, the attenuated apical flagellar segments, the quadrivit-
tate thorax and the dark lateral margins to the abdominal tergites.
0. gracilis has the apical flagellar segments less elongated and the
thorax subvittate; 0. griseipennis has the median prsescutal stripe
entire and the abdomen with a dark brown dorso-median stripe.

ments each with two long pectinations that exceed in length the seg-
ments that bear them; flagellar segments verticillate. Venation
with cell first M 2 small as in Tipula; cell M, long-petiolate. Male
hypopygium as in Tipula, the ninth tergite, pleurite and sternite being
entirely distinct; eighth sternite with a long, conspicuous median
appendage. Coloration as in species of the monilifera group of the
genus Tipula, the body with a capillary brown dorso-median line, the
praescutum with the interspaces set with tiny brown setigerous
punctures.

Genotype. — Ozodicera argentina van der Wulp (Argentina).
Enderlein (Zool. Jahrb., Vol. 32, pt. i, p. 27; 1912) places argen-
tina in his restricted genus Ozodicera under the mistaken belief
that the antennae are unipectinate. In reality, the antenna in the
male sex, at least, are long-bipectinate and of a structure that di-
verges widely from all species of the genus Ozodicera. Likewise in
its wing-venation which is almost identical with the normal type of
the genus Tipula and the simple male hypopygium this species de-
parts from the compact type of Ozodicera. The presence of ten
pectinate flagellar segments and the petiolate cell M 1 are ample char-
acters upon which to remove this fly from Ozodicera to a position
nearer the genus Tipula, to which it is obviously more nearly allied.
The genitalia and color of the body closely resemble those of species
of the monilifera group of the genus Tipula and it seems probable
that the true affinities of this fly are not far distant from this group.
I am indebted to Sefior Jorgensen for a specimen of this interest-
ing fly, taken at Esquina Grande, Catamarca, Argentina, April 7,

Frontal prolongation of the head pale brownish yellow, more pruinose
above; palpi dark brown. Antennae with the first segment gray pruinose; sec-
ond segment yellow; flagellar segments with the basal enlargement dark brown,
the remainder of each segment a trifle paler to produce a very indistinct bi-
colorous effect; flagellar verticils long. Head brownish gray with a very in-
distinct brown line on the vertical tubercle.
Pronotum brownish with an indistinct capillary dark brown median line.
Mesonotal praescutum dark gray with five brown stripes, the three intermediate
very narrow, being formed by the lateral margins and capillary median vitta
of the usual broad median stripe ; lateral stripes broad ; humeral region yellow ;
praescutal interspaces with a few dark setigerous punctures; scutum dark
gray ; scutellum dark testaceous brown ; postnotum light gray with a capillary
black median line. Pleura light yellow, gray pruinose; dorsopleural mem-
branes dull yellow. Halteres long, dark brown, the base of the stem paler.
Legs with the coxae pale reddish, sparsely gray pruinose ; trochanters dull yel-
low ; femora reddish brown, the tips indistinctly darker ; tibiae yellowish brown,
the tips narrowly dark brown ; metatarsi yellowish brown, the tips darkened ;
remainder of the tarsi dark brown; metatarsi shorter than the tibiae; claws
small, simple. Wings grayish, the apical cells grayish brown, the costal and
subcostal cells more yellowish; stigma pale yellowish brown; an obliterative
streak before and beyond the stigma, the latter in the bases of cells R, and R t .
Venation: Cell R, rather broad at the base; basal deflection of R i+S short;
cell ist M i small, almost regularly pentagonal ; petiole of cell M 1 short, about
as long as cell Ist M 2 ; m-cu punctiform.
Abdominal tergites brownish yellow with three broad dark brown stripes,
the lateral margins of the segments rather broadly pale, the caudal margins
indistinctly ringed with yellowish, most evident on segments six and seven;
sternites pale yellow, the terminal segments indistinctly pruinose. Ovipositor
with the long dorsal shield and the valves light chestnut brown, the straight,
slender tergal valves greatly exceeding the sternal valves, along the ventral
margin with scattered erect setae.

ticils conspicuous. Head light gray, more brownish adjoining the inner margin
of the eyes.
Mesonotal praescutum dark brown, the prasscutum stripes clear bluish gray,
margined with dull whitish gray ; the median stripe is split by a capillary dark-
brown line that broadens out behind, just before the suture enlarging into a
blotch; immediately laterad of this and occupying the praescutal interspaces a
similar short brownish line extending from the suture cephalad; interspaces
sparsely dotted with brown setigerous punctures ; lateral margins of the median
stripe at about midlength of the sclerite narrowly and indistinctly margined
with brown ; lateral margins and the humeral region of the dark brown ground
color; scutum dull gray, the lobes with a linear dark brown stripe; median
lobe of the scutellum and the postnotum gray pruinose, the latter with an
indistinct brown median line. Pleura brown, grayish pruinose; a dark brown
longitudinal stripe on the dorsal pleurites ; a dark brown velvety spot imme-
diately dorsad of the base of the halteres on the sides of the postnotum and a
small white area immediately before the halteres ; dorso-pleural membranes
dull yellowish. Halteres dark brown, the base of the stem and the base of the
knob paler. Legs with the coxae pale, grayish pruinose ; trochanters and femora
dull brownish yellow, the latter with an indistinct brownish ring immediately
before their apices; tibiae yellowish brown, the tips darker; tarsi brown; meta-
tarsi considerably shorter than the tibiae. Wings white, sparsely streaked and
lined with brown ; cells C and Sc strongly yellowish ; stigma brown ; small dark
brown marks at h, at the origin of Rs, midway between the two latter, and at
the tip of Sc ; larger but slightly paler clouds at the fork of Rs, connecting
with the stigmal spot, a large blotch in the end of cell R 2 and the middle of cell
R 3 ; a large blotch at the base of cells R and M and along vein Cu in cells M
and Cu for almost the whole length of this vein ; grayish clouds in the ends of
the anal cells ; the ends of veins M t , M,, M 3 , Cu t and 1st A are seamed with
brown. Venation : Base of cell i? 2 broad ; cell 1st M 2 subpentagonal ; m-cu
obliterated by the fusion of Cu ± on M 3+1 ; cells R 2 and jl^ are somewhat broader
than in T. wittei.
Abdomen with the first tergite gray pruinose ; remaining tergites dull yel-
low with three diffuse dark brown stripes that almost obliterate the ground
color except at the base of the sclerites ; sternites dull yellow, sparsely
pruinose. Ovipositor almost as in T. wittei but the dorsal basal shield less
elongate.
