REVISION OF THE OECOPHORIDAE — CLARKE 37 



pigmented sclerotized ring surrounding the base of the tubercle; on 

 ninth abdominal segment seta I ventrocephalad of II, rarely approxi- 

 mate to II {Endrosis^ Eofmannophila)^ usually about equidistant 

 from II and III, III much nearer to IV-V than to I, IV and V closely 

 approximate, VI rarely (Psilocorsis) on the same pinaculum with 

 iy_Y^ sometimes approximate to VII, VII unisetose. Legs and pro- 

 legs normal. Crochets in a complete circle, biordinal and, occa- 

 sionally, irregularly triordinal, never in a penellipse (or a ring broken 

 outwardly). 



Head with adfrontals extending to incision of dorsal hind margin 

 of epicranium; frons not extending to incision of hind margin; a 

 longitudinal ridge always present; epicranial seta L^ usually closer 

 to A^ than A^ is to A^ Ocelli normally six (reduced to 4 or 2 in 

 Hofmannophila and Endrosis) , arranged approximately in a parallelo- 

 gram ; 3 and 4 mostly in a straight line with 2 and 5 ; 3 and 4 closely 

 approximate. 



Pupa.— Smooth, or pubescent. Body usually depressed. Epicranial 

 suture present; frontoclypeal suture not distinct for its entire length 

 or reaching the meson ; maxillary palpi present, large, usually reach- 

 ing proximolateral angles of maxillae; caudal portions of antennae 

 lying adjacent on the meson, separating at their distal ends to expose 

 metathoracic legs ; maxillae from one-half to two-thirds the length of 

 wings; labial palpi rarely exposed {Endrosis) . Prothoracic femora 

 sometimes exposed, often not. Abdomen with segments 4 to 6 movable 

 and with deep incisions between these segments on dorsal and ventral 

 surfaces; genital and anal openings slitlike in both sexes; no hooked 

 setae on ventral surface of ninth segment; cremaster absent or shortly 

 developed. 



CLASSIFICATION 



In the classification of this family venation, palpi, general habitus, 

 and genitalia have been employed in this revision. The genitalia are 

 especially helpful and have been used to separate species as well as 

 genera. I have found the anellus of the male genitalia to be particu- 

 larly useful, and in most cases it is possible to separate species as well 

 as genera by this structure. 



The palpi are normally useful in the separation of genera but in a 

 few cases cannot be relied upon. The eyes and vestiture of the head 

 may be useful taxonomically, and Meyrick laid gi-eat weight on the 

 length of the ciliation of the antennae, but the modifications of these 

 characters appear to be too gradual for safe generic differentiation and 

 have not been employed in this paper. 



Venation is usvially reliable within a genus, but occasionally unusual 

 venation is encountered. A large niunber of genera have nearly iden- 

 tical venation, but such cases are easily separable on genitalia or ex-
