Characters. — Face smooth. Palpus moderate to long, slender, second joint rather long, 
smooth-scaled, third joint in cf moderate, in Q9 long to very long. Tongue present. Antenna about as 
in Jodis. Pectus slightly hairy Femora glabrous. Hindtibia in cf dilated with hair-pencil, in both 
sexes with all spurs. Abdomen not crested. Forewing with costa arched, apex moderate to rather sharp, 
termen oblique, more or less curved, cell less than one-half, DC? incurved, so that R? appears almost 
as its continuation, DC? arising somewhat distally, SC! stalked with SC??, usually anastomosing with C 
(but see cArysolineata zygophyxia), SC? normal (in o/rvescens anastomosing with SC!). R! connate or more 
usually very short-stalked, M! separate; hindwing elongate, apex nearly rounded, termen crenulate or 
subcrenulate (excepting Persimilis) with a tail at R? and (excepting acte and fersimilis) a smaller tooth 
at R! and an excision between, cell rather short, DC? strongly oblique, somewhat curved, SC? arising 
distally, somewhat curved, C shortly appressed to cell near base, rapidly diverging, SC? stalked
