1914]. Tipulidae from Fiji Islands. 241 
Tribe Eriopterini. 
Gonomyia (Leiponeura) fijiensis, sp. n. 
Thorax brown, lateral margin of the praescutum yellow; wings with 
the costal margin yellow, the membrane light brown and hyaline diver- 
sified, stigma lacking. 
Male, length, 4.9 mm. Female, length, 4.8-5.1 mm.; wing, 4.3- 
4.4 mm. 
Male: Rostrum and palpi dark brown. Antenne light sulphur 
yellow, the flagellar segments a little paler. The head bright sulphur 
yellow with three pale brown marks, a median one on the frontal tubercle 
and others on the sides of the vertex. 
Pronotum light yellow. Mesonotal praescutum dark clove-brown 
the lateral margin between the pseudcsuture and the transverse suture 
yellow, scutum, scutellum amd postnotum dark brown. Pleure light 
yellow, a broad brown lateral stripe, deepest ventrally fading into the 
yellow of the dorsal pleurites above, extending from the ventral surface 
of the cervical sclerites through the halteres to the posterior portion of 
the mesonotal postnotum; the area between this stripe and the praescu- 
tum is light yellow suffused with brown near this stripe; sternites dark 
brown. Halteres light sulphur-yellow. Legs, fore cox light sulphur- 
yellow except the extreme tip which is dark brown; trochariters light 
brown; remaining coxe dark brown on the. basal half, paler brown 
apically and on the trochanters; remainder of the legs broken off and 
confused in the vials with the legs of several other species, but they are 
probably uniform dark brown. Wings with the costa and the subcosta 
conspicuously bright sulphur-yellow, remaining veins brown; wing 
suffused with brown and variegated in places with hyaline, as in cell Ri 
which completely lacks a stigma, in cell R, lst Mz and elsewhere. Vena- 
tion as in figure 3. 
Abdominal tergites brown, broadly edged with yellow on the caudo- 
lateral margins, the brown always continuing to the caudal margin as a 
narrow median line except in the Sth tergite where the lateral and 
caudal margin is broadly yellow all around; sternites brown, very nar- 
rowly edged with paler on the caudal margin; pleurites broadly and 
conspicuously yellowish. Hypopygium with the 9th tergite short, broadly 
concave, yellow. Pleurites rather short, cylindrical, yellow, clothed 
with long pale hairs, bearing at the tip two appendages; the dorsal 
appendage is entirely fleshy with two arms, the one directed caudad, the 
other cephalad, the caudal arm densely clothed with abundant pale 
hairs, the cephalic arm with a chitinized bristle at the tip and about four 
smaller bristles on either side, subequal in length and evenly spaced. 
The ventral appendage is a long simple curved hook, very strongly 
chitinized. The 9th sternite is very high, convex and bears at its tip 
two strongly chitinized forked appendages that are directed caudad, the 
outer fork being cylindrical, acute, the inner fork flattened, twisted and 
directed entad. The penis-guard viewed from above (fig. 9) is narrow 
_at the base, broadening toward the tip, the lateral edges chitinized and
