In addition to the generic characters which have been pointed 
out, I may say that the wing is heavily fringed with long hairs. 
and the veins are covered with scales. The venation is shown 
in fig.9. 
Of the life history Professor Smith has given an account in the 
Canadian Entomologist for 1902. .

PELOREMPIS NOy. gen. 
Two peculiar larvae were found in a pail of cold spring water 
at Saranac Inn by Professor Needham, June 1900. One of them 
was kept till the fly emerged; the other till it had changed into 
a pupa. Both the larva and adult differ so much from all 
the species of the Culicidae that a new genus is necessary to 
contain it. 
Female. Large species resembling Psorophora in gen- 
eral appearance. Head rounded; occiput strongly developed; 
proboscis a little longer than the hight of the head with rounded 
labellae; palpi longer than the proboscis, four jointed (not 
counting the small basal joint [see fig. 10, 11]; the two end 
joints each longer than the preceding; antennae 15 jointed, the 
basal joint disklike, the second one short and thick, the rest, 
including the apical one, small, subequal in length, verticillate 
with a few hairs of moderate length; eyes kidney-shaped, much 
cut out around the base of antennae, separated from each other 
on top of head by only a narrow space; ocelli wanting; thorax
