REVISION OF THE OECOPHORIDAE — CLARKE 35 



recognized 19 genera and 121 species of North American Oecophori- 

 dae. In the Barnes and McDunnough list^ the authors followed 

 Busck in recognizing 19 genera but enumerated only 98 species, the 

 remainder being transferred to other families. Meyrick ^ recognized 

 17 North American genera and 104 species. 



EXCLUSION OF UNRELATED FORMS 



Within the family I recognize 22 genera and 117 North American 

 species. Six genera, 19 species, and 1 race are described as new in 

 this paper. 



The genus Etidrosis is retained in the family with doubt. Busck * 

 transferred TAclonella to the Cosmopterygidae in 1932. I have re- 

 moved Eumeyrickia and Gerdana from the family and have placed 

 them in the families Ethmiidae and Blastobasidae, respectively. For 

 part of the species formerly placed in Borkhausenia I have erected the 

 genus Anoncia and have referred it to the Cosmopterygidae. For 

 Semioscopis acertella Busck I have erected the genus Antequera and 

 have placed it in the family Cosmopterygidae. 



CHARACTERS OF THE FAMILY 



Head usually smooth, with loosely appressed scales; often with 

 raised side tufts. Antenna simple to strongly ciliated, usually with 

 pecten on basal segment but frequently with pecten absent or slightly 

 developed. Labial palpus well developed, usually long, upwardly 

 curved, variously scaled; terminal segment acutely pointed. Maxil- 

 lary palpus short, filiform, appressed. Prothoracic and mesothoracic 

 legs normally slender, moderately long; posterior tibia with long rough 

 hairs above. 



Fore wing with 12 veins (or 11 by coincidence of veins 7 and 8) ; 

 lb furcate at base; Ic always preserved, at least at margin; 7 and 8 

 stalked or coincident, 7 to costa, apex or termen. 



Hind wing with eight veins or rarely seven by coincidence of veins 

 5 and 4 {Endrosis) ; veins 6 and 7 remote, subparallel; veins 3 and 4 

 normally stalked or connate (rarely separate); 8 free; 5 nearer to 

 4 than to 6 (except Oecopliora and Mathildana). 



Male genitalia symmetrical; harpe with or without clasper, base 

 of harpe broadly attached; sacculus well defined; cucullus rounded 

 or pointed except in Carcina^ where it is greatly reduced and weakly 

 sclerotized. Anellus a simple plate or with moderately or well de- 

 veloped lateral processes. Aedeagus with very small "blind sac" or
