REVISION OF PEORIINAE AND ANERASTIINAE 61 



Forewings Avith 10 veins; vein Cu2 from before lower outer angle of 

 cell; Cui and M3 from angle, stalked; M2 absent; Mi from upper outer 

 angle of cell; R2+4 stalked, from just before the upper outer angle; Ri 

 from well before angle. Hindwing with 6 or 7 veins; vein Cu2 from be- 

 fore lower outer angle of cell; Cui and M3 from angle, stalked for at 

 least one-half their length, sometimes fused; M2 absent; Mi from just 

 below upper outer angle of cell; Rs and Sc from upper angle, stalked 

 for at least one-half their length. 



Male genitaha with uncus bifid, setose ventrally, terminating in 

 minute ventrally directed hook. Gnathos with medial process U- 

 shaped. Transtilla absent. Juxta membranous, margin sclerotized 

 anteriorly. Vinculum variable, U-shaped or V-shaped, anteriorly 

 rounded or bluntly pointed. Valvae broadly rounded, variable in out- 

 Une, setose distally. Aedeagus tapering posteriorly, vesica armed. 



Female genitaha with ovipositor lobes triangular, moderately setose. 

 Apophyses rather straight and uniform. Ductus bursae moderately 

 broad. Bursa slender and unarmed. Ductus seminaHs leaving near mid- 

 point of ductus bursa. 



Key to the Species of Coenochroa Based Upon External Structure 



1. Central beak of frons protruding beyond rim (figs. 45, 46); costa paler than 



cell; R2 usually first to branch from stalked R2+4 illibella 



Central beak of frons not protruding beyond rim; costa not pale; R^ usually 

 first to branch from stalked R2+4 2 



2. Central beak of frons with irregular tip, just attaining end of rim (fig. 47) ; 



Atlantic and Gulf Coastal Plain bipunctella 



Central beak of frons pointed and small, not attaining end of rim (fig. 44) ; 

 Texas and Western United States californiella

Diagnosis. — This is the only member of the genus in which the 

 central beak of the frons does not attain the rim. The genitaha are 

 identical to those of illibella, a species which lacks the discal spot 

 and has a distinctive pale costa. 



Description. — Frons with protuberance cylindrical, ventrally 

 about as long as wide, rim slanting about 45°, teeth projecting for- 

 ward, central beak a very small cone not reaching rim, vesture light
