Subfamily OENOCHROMINAE 

 1. Dichromodes exocha sp. nov. 



S, 27 mm. Head whitish grey, irrorated and dotted with dark fuscons. 

 Palpus rather more than twice as long as diameter of eye ; above mixed whitish 

 grey and dark fuscous, sides blackish fuscous, first joint beneath sharply whitish. 

 Antennal pectinations about three times diameter of shaft. Thorax and abdomen 

 whitish grey, mixed with fuscous ; forefemur fuscous on inner side, foretibia and 

 tarsus fuscous except at extremities of joints; hindtibia slender. 



Forewing shaped about as in stilbiata Guen. ; whitish grey, rather glossy, the 

 markings blackish fuscous ; a fine, slightly curved line near the base ; a thicker 

 but less dark line shortly beyond ; a strong, fairly straight line from before 

 one-fourth costa to beyond one-fourth hindmargin, accompanied distally by a 

 dark shade which narrows to a point on costa; a rather narrow median band, 

 its proximal edge indented on the veins, its distal with a moderate double pro- 

 jection in the middle and curving distad at hindmargin ; an elongate-oval black 

 cell-mark in this band (distally to its middle) ; a fine, slightly sinuous brown 

 line nearly 3 mm. from termen, separated by a whitish grey line from a sharp 

 blackish subterminal band, narrower and better-defined than that of stilbiata 

 swollen near costa and again at hindmargin, and with a double distal projectiou 

 at R'-M 1 , reaching about halfway to termen ; terminal line very slender or 

 obsolescent, but with very sharp triangular black dots (almost wedges) between 



the veins; fringe weakly dark-spotted opposite the veins. Hindwing fuscous, 



slightly paler at costa ; faint traces of a sinuous pale postmedian line, best 

 expressed at abdominal margin, where it is followed (towards tornus) by weak 

 beginnings of alternately dark and pale lines. 



Forewing beneath pale fuscous, with a darker submarginal band, its distal 

 edge (especially anteriorly) darkest ; a slight pale shade proximally to this band. 

 Hindwing beneath slightly more irrorated with whitish grey, the subterminal 

 band and its proximal pale shade better expressed.
