﻿Preliminary description of a new family 

 and three new genera of Mallophaga.

Trichophilopteridae n. fam. 



Among a very large, undetermined material of Mal- 

 lophaga, which I have to my disposal there is also a curious 

 form from a PropitJiecus sp., which belongs to Stobbe's new 

 genus Trichophiloptenis , and which proves to be a close 

 relative, though distinct, to Tr. babakatophilns Stobbe. The 

 genus differs in so many important characters from other 

 genera, that it seems me well justified to place it into a dis- 

 tinct family. 



Mallophaga of Ti'ichodeclesA\\<.e appearance, living on 

 Proshniœ with five-jointed antennae and two-clawed tarsi. Head 

 strongly chitinized at the sides and armed with strong chiti- 

 nous hooks; underside of head with a median furrow and with 

 the jaws shaped and placed in a manner very much remind- 

 ing of the conditions in the family Trichodectidœ BURM. — 

 The first known Mallophaga of the suborder Ischnocera with 

 two claws infesting mammals. 



Typus: Genus TricJiophilopterus Stobbe. 



Species: i) TricJiophilopterus babakatophilns Stobbe. 



2) Trichophilopterus stobbei n. sp. — from 

 Propithecus sp. — (to be described at a later occasion).
