Studies on Tipulidae II. 199 
vatica in having a yellow line on each side of the thorax. Whether 
other differences exist I cannot tell, not having had an opportunity 
for eomparing specimens. 
3. Gnophomyia fascipennis n. sp. and @. caloptera n. sp. from 
Brazil, described below. 
These three species are more slender, less robust than those of 
the preceding group, the joints of the antennae are more elongate, 
the legs more slender etc. They come remarkably near one of the 
groups of GFonomyia, as will be shown below; they seem to difter 
however, as far as observed, in the constant presence of the mar- 
ginal crossvein, and in the structure of the forceps. 
Gnophomyia cordialis n. sp. ö. Yellowish-ferruginous; 
“ a spot in front of thorax, two stripes upon it, and hind part of me- 
tanotum, are deep-black; wings tinged with brownish. Long. corp. 
8—6 mm. 
Head black above, yellowish below; rostrum somewhat prolonged, 
yellow, palpi brown; antennae: scapus yellow, except the tip of 
24 joint, which is brown; flagellum brown. Thorax reddish - yellow; 
dorsum shining; a spot on the miesonotum (where the median tho- 
racic stripe usually begins), and two lateral stripes, deep black; 
the latter reach the scutellum and send out a short branch towards 
the root for the wings; posterior part of the metathorax with a large, 
black, truncate-cordiform spot. Halteres yellow, with a brown knob; 
legs reddish-yellow, tips of femora-and tibiae faintly brownish; tarsi 
brownish towards the tip. Abdomen, including genitals, reddish- 
yellow. Wings with a brownish tinge, and with two ill-defined and 
faint spots of a paler color; the one precedes the central crossveins; 
the other, in the shape of a crossband, begins at the tip of the 
second vein. 
Hab. Australia (Lotz, 1834, Vienna Mus.), 3 male specimens. 
NB. The venation of this species is exactly like that of @no- 
phomyia (see Monogr. of N. Am. Dipt., Vol. IV, Tab. I. f. 5); all 
the characters are those of the Eriopterina. Legs comparatively 
stout, with sparse, short, stiff bristlelike hairs. The male forceps, 
small and difficult to study in dry specimens, seems to resemble that 
of Gnophomyia. Altogether, I do not know, at present, a better 
place for this species than this genus. 
Gnophomyia fascipennis n. sp. &Q. Body, halteres and 
legs altogether black, except a whitish-yellow spot on each side, on 
the humerus. Wings grayish-subhyaline, with a brown cerossband; 
its breadth near the costa is limited by the tip of the first and the
