According to literature and a specimen compared witli the type 

 by Dr. McDunough the type form is very similar to P. ornkhogalli 

 but shows a slightly paler central area on the primaries and a trace of 

 a discal spot on the secondaries. 



A form of this, exactly corresponding to eudiopta occurs with the 

 typical form and as the species is of economic importance, a name 

 may prove of some value. To this parallel development to eudiopta 

 the authors apply the name 



Prodenia praefica form eudioptoides nov. 



Practically identical in superficial appearance to P. ornilhogaUi form 

 eudiopta Gn. but obviouslj' a form of P. praefica by the heavier build and the 

 clasper of the male genitalia; discussed above.

 same blackish-brown of the patagia as to appear dark with a contrasting inner 

 margin; basal line obscured; t. a. line single with a few pale scales basad, waved, 

 slightly rounded out to vein 1 where it is bent inward to a point, thence oblique 

 outwardly to inner margin where it is most strongly marked; orbicular obso- 

 lescent; reniform obsolescent, with dark center, edged with some pale scaling; 

 t. p. line single with some pale scaling distad, outwardly oblique from costa, 

 waved and bent outward around the reniform, bent inwardly about on vein 5, 

 waved to near vein 1 where it is produced to a point, thence as a heavy crescent 

 to inner margin ; three pale dots present on costa between t. p. and s. t. lines ; 

 s. t. obscurely marked by pale scaling ; a series of light points present on the 

 ends of the veins, the space between being occupied by dark dots; fringe long 

 and mottled. Secondaries hyaline, heavily suffused with fuscous from near 

 middle to outer margin, the veins darker; fringe pale fuscous with a trace of
