A Monograph of Culioidae. 
brown scaled, proboscis brown, a light band, narrow on the 
dorsal and wider on the ventral aspect, at the apex of the 
proximal half ; clypens brown, eyes brown and gold. 
Thorax dark brown, pro thoracic lobes with slender curved 
light brown scales, mesonotuxn with slender curved scales a 
distinct bare (dark) median line, immediately -lateral of which 
on either side is a broad stripe of bright brown scales, then a 
light golden-brown or ochraceous stripe extending cephalad from 
the scutellum to nape, external to these on the caudal half are 
the darker brown scales, and the lateral portion of the dorsum 
is covered with the lighter brown scales, scutellum dark, with 
the light brown or ochraceous scales, and long light bristles on 
the margin ; pleura ashy-brown, with white scales : metanotum 
dark brown. 
Abdomen dark, heavily and closely covered by flat ochraceous 
scales, two tiny dark submedian points not large enough to call 
spots, and yet very distinct, on all the segments but the first, 
which has a large bunch of almost white scales and light hairs, 
ventrally the abdomen is also covered with ochraceous scales, 
but not so heavily as dorsally. 
Legs : coxae and trochanters mostly light scaled, femora 
dorsally sprinkled with dark brown and ochraceous scales, darker 
towards the apex, but the very apex white, ventrad, caudad 
and cephalad aspects ochraceous. Tibiae much like femora but 
darker, and on the hind legs have a distinct dark apical band, 
metatarsi on fore legs much like tibiae, and all the following joints 
missing, on the mid legs also much like tibiae, tarsal joints dark, 
the first and second with small ochraceous basal spots, on the 
hind legs the metatarsi are quite dark but still slightly sprinkled 
with light scales, and it and all the tarsal joints except the 
fourth are heavily basally white-banded, the fourth dark, all 
ungues uniser-rate. 
Wings clear, mostly dark-scaled, especially near the costa, 
the sixth long vein mostly dark, first sub-marginal a little longer 
and about half the width of the second posterior cell, the stem 
in each case about two-thirds the length of the cell, cross-veins 
nearly equal in length, the posterior about its own length distant 
from the mid ; halteres mostly light, a little darkened on the 
knobs. 
Length. —5-6 mm.
