spotted legs give it some resemblance to Culex tigripes, but the 
banded tarsi and proboscis and general ornamentation will at 
once separate it. 

Genus 23. MELANOCONION. nov. gen. 
(Plate XII.) 
Palpi short in the female and long in the male. Head clothed 
with narrow-curved scales and upright forked ones, the latter 
predominating ; proboscis expanded apically. 
Thorax covered with narrow-curved scales, also the scutellum. 
Legs unbanded ; ungues of the 2 very small, equal and simple ; 
in the ¢, those of the fore and mid unequal, uniserrated, of the 
hind equal and simple. Femora swollen at the base, also at the 
apex, and also the apices of the tibiae swollen. 
Wings with the veins covered with dense broad scales on the 
apex of the wings and along the costal border (Plate XII.), upper 
border with black spine-like scales. 
This genus is separated from Culex on account of the 
squamose character of the wings, which are very characteristic. 
They are all small black gnats, which bite viciously and which 
occur in swamps and woods. 
Six species are known, namely atratus, Theobald, rima, Theo- 
bald, humilis, Theobald, and the three new ones described here. 
The three first I placed provisionally in the genus Culex.

Note on the larvae and pupae of Melanoconion atratus. 
Dr. Grabham writes as follows :— 
“T have collected the larvae in the permanent ponds in the 
Ferry Swamp, where they are present in great numbers ; neither 
the minnows nor dragon-fly larvae appear to destroy them. They
