Notes on Psyllidae (Homoptera). 



By D. L. Crawford, College of Hawaii, Honolulu 



Two brief, pre-war papers on Psyllidae (Homoptera) con 

 tributed by two Germans, require a few notes of elucidation 

 and comment. 



One of these, contributed by Dr. G. Enderlein^ describes 

 several new genera and species from Formosa. One of these 

 new genera, Agonoscena, appears to be identical with Pauroce- 

 phala Crawford. Enderlein makes an old species of Rhinocola 

 {R.targioni Licht.) the type of his new genus and includes, also, 

 a new species from Formosa {A. Sauteri). The latter species 

 seems to be identical with Paurocephala psylloptera Crawford, 

 which is widely distributed over tropical Asia and the out- 

 lying archipelagoes, While I have seen no examples of En- 

 derlein's Formosan species, his figures and description con- 

 vince me of the identity of his and my species. 



As Paurocephala psylloptera- antedates Enderlein 's^gowo.y- 

 cena Sauteri, the latter should be sunk in synonymy. 



Enderlein's genus Agonoscena retains its validity, howe\er, 

 until some other disposition is made of its type species. Rhin- 

 ocola has been made to embrace a large number of unrelated 

 species, many of which must eventually be referred to other 

 genera. The type of this old genus, R. aceris Linn., is inter- 

 mediate between Livia and Aphalara^, but few of the other 

 species can be retained properly in the genus. 



For another species of Rhinocola, {R. ericae Curtis) Ender- 

 lein erects the new genus Strophingia. This seems scarcely 

 justifiable since R. ericae and R. targioni are similar and not 

 generically distinct. 



The second paper^ supplements Aulmann's very incomplete 

 catalog of the psyllid species of the world. A few items in 

 this supplement suggest some comment.
