Genus Homohadena Grt. 



[1873. Bull. Bnff. Soc. N. H., i, 1890. ] 



Medium-sized species with the habitus of Hadena, but with rather 

 distinctive maculatiou. Head moderate or small; front smooth; tongue 

 strong ; palpi stout, attaining middle of front. Eyes naked, with variably 

 distinct lashes — this character becoming evanescent here. Antennae 

 simple, scarcely ciliate even in the male. Thoracic vestiture mixed 

 scales and hair. Collar with crest marked but scarcely prominent. 

 A very small, indefinite, basal thoracic tuft, vestiture else smooth. 

 Abdomen untufted. Legs with rather long, loose hair; tibise unarmed, 

 not spinose. Primaries rather elougate-trigonate, apices and outer 

 margin slightly rounded. Ovipositor of female somewhat exserted. 



The male genitalia are of the same type as in Oncocnemis, and this 

 genus is its close ally, differing chiefly in the lack of the claw to fore- 

 tibia. 



The species are fuscous gray or brown, with the median lines some- 

 times wanting, and when present, distinct, black, and single, often con- 

 nected by a longitudinal black streak or by an inward tooth from the 

 t. p. line.

The genus is very compact and the species scarcely form distinct 

 groups, though readily separable into series on cliaracters of macula-
