CRYPTOPHAGIDAE. 135 



Sub-Family V.— TELEPHANIN^. 



In this sub-family tlie anterior coxal cavities are broadly closed 

 behind, as in the first sub-family, but the third joint of the tarsi 

 is lobed beneath ; the maxillaj are exposed, and the gence but 

 slightly prominent. 



Two genera occur in our fauna, the second of which has been 

 introduced in articles of commerce: — 



Antennse with first joint elongate. Telephaniis. 



AntonnjE with first joint short. Psauimcecus. 



The latter has been found once in Oregon, and its synonymy 

 affords an excellent example of confusion, which can be only 

 removed by exhaustive studies of each family of insects in detail. 

 This species was first described from Mauritius as Psammoecus 

 Z)(^'y'art?2??sfi: then by Wollaston from Madeira as Cryplarnoiyha 

 muHse; and finally by LeCoute from Oregon as Pseudophanun 

 aignatus.
