These little flies closely resemble mosquitos in size and form; 
but may easily be distinguished from them by the venation of 
their wings, and in that the veins are not furnished with scales 
[pl.48, fig.8]. The antennae are about 15 jointed, and differ but 
slightly in the two sexes; the legs are long and slender; and the 
caudal end of the abdomen of the male is enlarged. The family 
includes only a single genus, Dixa. The flies appear to be rare 
in America; at any rate are rarely observed. 
The larvae of several European species are known. The fol- 
lowing is the first published description of the larva of an 
American species, as far as I am aware. oY ee 
Dixa modesta nov. sp. 
Mr Henshaw kindly compared this species with Loew’s types 
in the Cambridge Museum and he found that it differs from all 
of them.
