Genus OIKETICUS Guilding 



The genus is found in the hotter parts of Amer-

 found in Central America. It is also represented 

 in southern Asia and in Australia. Three species 

 occur in the United States one in southern Cali-

 Grote, and the male is delineated in Fig. 208. 

 The wings are pale smoky brown, with darker 

 maculation at the end of the cell and just beyond in the primaries.
