EiLEY, Charles Y. — Classification of the mites. 



(Amer. Naturalist, July, 1881, xv, pp. 577-578.) 



Abstract of letter from Dr. G. Haller, in whicli he states that Acarina 

 have three pairs of maxillae, a true labium with palpi, two pairs of abdomi- 

 nal and [two pairs of] cephalothoracic legs ; he does not consider that they 

 belong to the Arachnida, but believes they are much more nearly allied to 

 the Crustacea, and must form a fifth class of Arthropoda, equivalent to Crus- 

 tacea, Myriapoda, Arachnida, and Mexapoda. 



Further notes on the pollination of Yucca and on Pronuha and 



Frodoxus.

Separate. (Furthernotes [etc.]) 



[Salem, July, 1881,] pp. 1-23, Fig. 1-16.) 



Recapitulation of observed facts concerning Pronuha yuccaaella and its con- 

 nection with the pollination of Yucca; describes and figures the generic and 

 specific characters of Pronuha, P. yuccasella, P. maculata n. sp., Prodoxus, P. 

 decipiens, P. intei-medms n. sp., P. marginatus n. sp., P. cinereua u. sp., P. cenea- 

 cens n. sp., Hyponomeuta, H. maUneUa, H. multipunctella; establishes and char- 

 acterizes the new family Prodoxidos (Tineina) for Pronuha and Prodoxus; dis- 

 cusses the structure of the ovipositor in lepidoptera, and the habits and func- 

 tions of Pronuha yuccasella and Prodoxus decipiens; proposes to restrict the 

 prior trivial name quinquepunctella [proposed for a Yponomeuia'\ to that form 

 of Prodoxus decipiens which it proves to be, and cites the trivial name jjara- 

 doxica [used without description] as a synonym of P. decipiens.
