236 LEPIDOPTERA HETEROCERA 
section well marked, cell less than one-half, DC? incurved, DC? arising further distally (sometimes much 
further, in maculata very little further), SC! arising close to or out of the stalk of SC?5, in the type and a 
few others stalked to beyond R!, R! usually stalked, M! connate or short-stalked ; hindwing with termen 
slightly bent at R?, or strongly rounded, tornus usually pronounced, inner margin long, cell short, 
DC slightly oblique, usually nearly straight, sometimes DC? and DC? separately (weakly) incurved, 
forming an angle at origin of R?, C anastomosing with cell at a point near base, rapidly diverging, 
M! stalked, M? from close to end of cell (Pl. 4, Fig. 1 7). c genitalia with uncus parallel, bifurcate at 
the extreme tip, socii terminating in a strong horn, gnathos pointed, harpe with arum-lily-shaped 
clasper, penis pestillate. 
Early stages unknown. 
Associated with Bería in the form of DC of the forewing. That this can have been independently 
acquired is suggested by a few other genera, but the genitalia and one or two other characters point to 
the possibility of a real connection in the present case, The superficial aspect is totally dissimilar. There 
may probably be a relationship with Hemistola through C. ovifera and Section III of that genus. 
Type of the genus : Conmostola laesaria (Walker) — Iodis laesaria, Walker — Comostola ferlepidartia, 
Meyrick (1888). 
Geographical distributlon of species. — Indo-Australian, 
SEcTION I. — Termen of hindwing not strongly rounded, but nearly always bent at R*; 
antenna of Q usually serrate (Comostola, Warren).
