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 lig.9.

PELOREMPis nov. gcn. 

 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 emergi.'d; the other till it had changed into 

 a pupa. Both the larva and adult differ so much from all

 eral ai)pearance. Head rounded; occiput strongly developed; 

 proboscis a little longer than the hight of the head with rounded

 joints each longer than the i)receding; antennae 15 jointed, the
