restricted by Prout form a natural group, which embraces 

 centrophylla, Meyr., cala'ina, Turn., epiTnitra described below, 

 and orthodesma, Low. In both, cala'ina and orthodesma the 

 terminal joint of palpi in female is fully |, and the only 

 structural distinction appears to be the angling of the termen 

 of the hindwing on vein 4, which is insufficient. The genus, 

 as I conceive it, is large but not unmanageable, comprising 

 some 120 species. 



Gelasma I seres, n. sp.

Very like P. albicostata, which differs in the longer palpi 

 (IJ) and whitish cilia.
