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.

PELOREMPis nov. gen. 



Two peculiar larvae were found in a pail of cold spring water 



at Saranac Inn by Professor Xeedham, 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 Oulicidae 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, eubequal 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 nariow space; ocelli wanting; thorax
