GENUS X. — ORTHOLITHA (lliJBN.). 



Rather large moths, fore-wings with the costa straight ; grey or brown, with the central 

 area distinct, and bounded by transverse lines ; the basal area divided by a transverse line, the 

 subterminal line more or less distinct and regular, and the rest of the wings traversed by dark 

 and pale and often very suffused transverse lines. The tip is divided by a dark dash extending 

 to the subterminal line, and the hind-wings are paler, either without or with much less distinct 

 markings ; and their inner margin extends far beyond the hinder angle of the fore-wings. The 

 antennae of the males are shortly pectinated, and occasionally furnished with short thick truncated 

 and ciliated processes ; the palpi usually extend considerably beyond the head. The hind
