INTRODUCTION. 



2. Prothoracic stigmata difficult to perceive 

 on account of the prominence of the sides 

 of the prothorax. 



A. Anterior coxae short and conical. 



a. Tarsi two-jointed Leptotyphlin^e. 



b. Tarsi four-jointed Evjesthetin^. 



B. Anterior coxae large, prominent and 



conical. 



a. Vertex without ocelli. 



a*. Last joint of labial palpi dilated, 



very large, crescent-shaped Oxyporinje. 



b* . Last joint of labial palpi not, or not 

 strongly, dilated. 

 of. Posterior coxae conical. 



a\. Palpi with the last joint very 



small, subulate PiEDERiNiE. 



b\. Palpi with the last joint equal 



to the preceding Pinophilin.e. 



6f . Posterior coxae transverse. 



a%. Posterior trochanters small, one- 

 fifth the length of the femora ; 

 head with a distinct neck .... Oxytelinje. 

 b%. Posterior trochanters large, one- 

 third the length of the femora ; 

 head without a distinct neck. . Phlceochaein^;. 



b. Vertex with two ocelli Omaliinje. 



C. Anterior coxae transverse, sublinear. 



a. V ertex without ocelli ; elytra covering 



the greater part of the body Proteinin2E. 



b. Vertex with one ocellus; elytra only 



slightly passing the metasternum .... Phlceobiin^]. 



D. Anterior coxae globose Piestinje. 



II. Prosternum with deep furrows for the reception 



of the antennae ; antennae nine-jointed, with an 



abrupt club ; tarsi three-jointed Micropeplin^e. 



Several of these sub-families might perhaps be classed together 

 and doubtless others will have to be added. 



Family 12. PSELAPHIMl. 



Very small insects, which are especially noticeable for the extra- 

 ordinary development of the maxillary palpi (although these vary 

 very much, and in one group are rudimentary), and for their abbre- 

 viated elytra ; mentum small, more or less quadrate ; antennas inserted 

 on the front, above the base of the mandibles ; abdomen in great part 

 exposed, consisting of five, six or seven segments, and with at least 

 part of these connate ; tarsi with not more than three joints ; anterior 

 coxce conical, contiguous.
