Family RHYACOPHILID^. 

 Genus DiPSEUDOPsis, Walker. 

 This genus was characterized by Mr. Walker in pt. 1 of the 

 British Museum Catalogue of Neuropterous Insects, p. 91 (1852), 

 from a single specimen from Port Natal {D. Capensis), and con- 

 sidered as belonging to the Sericostomidce. Since then a second 

 species (described below) has been received from China ; and as 

 the maxillary palpi are five-jointed in both sexes, and present no 

 structural difference, I think it should more properly be referred 

 to the Rhyacopliilidce. It is a very distinct genus, with 3. 4, 4 

 spurs and a remarkable development of the prothorax (especially 

 in the Chinese species), more so than I have observed in any 

 other genus of Phrygmiidce ; this part forms above a very evident 

 collar, deeply divided in the middle.

Antennae yellow, annulated with brown ; head fuscous, the 

 lateral and hinder margins yellowish ; palpi ochreous, slightly 

 fuscous ; prothorax large, conspicuously yellow (sometimes 

 slightly fuscous) ; mesothorax pitchy fuscous ; metathorax tes- 

 taceous ; abdomen fuscous ; legs yellow ish-ocherous, deeply con- 

 cave on the inner side; anterior wings straw yellow (sometimes
