Diagnosis. — Tlie genus may be easily recognized by the combina- 

 tion of a toothed protuberant frons and longitudinal wing pattern. 

 Martia has a somewhat similar frons, but the wing pattern is predom- 

 inantly transverse. The wing maculation of Anerastia is similar to 

 that of Coenochroa, and the frons is toothed, but not protuberant. 

 The bifid male uncus is unique to Coenochroa. 



Description. — Frons with prominent anterior protuberance ter- 

 minating in dorsoposteriorly sloping closed rim of irregular teeth sur- 

 rounding central beak (figs. 44-47); labial palpi porrect or deflexed; 

 maxillary palpi rudimentary, naked, usually hidden by labials; tongue 

 reduced, usually hidden by palpi; antennae compressed, each segment 

 bearing pair of perpendicidarly projecting ciha ventrally near distal 

 end, male shaft scaled dorsally, ventrally and laterally bearing dense 

 fine recurved ciha, female shaft scaled dorsally and laterally, ventrally 

 with fine sparse recurved ciha; oceUi small, covered with scales.
