Genus CHOGADA. 



Xearest to typical Alcis {A. reparidaria). Forewing comparatively narrower 

 and longer ; outer margins less uneven ; more oblique ; venation similar, excepting 

 that the first subcostal is emitted further from end of the cell. Body shorter, stouter ; 

 palpi larger, more distinctly separated, third joint longer, distinct, clavate; antennae 

 longer, with much longer ciliated branches to one-third the tip, the branches being 

 curved inward beneath. 



Ti/pe, 0. alienaria. 



This genus comprises a large and widely distributed group of species, which 

 are distinguishable at a glance from its allies by the peculiarity of the pattern of the 

 markings on both upper and under sides, and the possession of a prominent, mostly 

 tridentate, whitish cell spot on both wings.

 cell ; middle area also slightly brown speckled. Thorax brown speckled ; a black band
