 Le?^^ ^P^*^'^^ somewhat reminds one of the " Botys egenalis " of 



109. ASOPIA HIPPONALTS. 



Asopia hipponalis. Walker, Cat. Lep. Het. xvii. p. 3/4 (1859). 

 One specimen of this Australian species.

 One specimen.

112. DiASEMIA GEOMETRALIS. 



Lepyrodes geotnetralis, Guenee, Delt. et Pyral. p. 278 (1854). 



Two specimens. Notwithstanding the arrangement of their spots, 

 the form of their wings seems rather that of Diasemia thau 

 Ijepyrodes. 



113. Stenia, sp. 



Three specimens, all far too much rubbed for description. 



The following species may be referred to Stenia— Catadysta 1 

 ^/«<aZi.9 of Walker, from Ceylon, and C.fraterm, Butl., from Natal, 

 both of which are nearly allied to C. ornatalis of Europe.
