PTYCHOPODA VITTICOSTATA, new species. 



Superficially nnich like /*. griseocostata Warren, from which it maj^ 

 be distingiiished by the following points; the red coloring is paler; 

 the ochreous gray costal streak is much broader and reaches to apex 

 instead of stopping short at two-thirds of costa; there are clear traces 

 of red cross lines especially of a much outcurved postmedian and a 

 broad sul)marginal. The hindwing appears to be angled at vein C, 

 owing to the red marginal l)and running out into the ^^ellow fringe, 

 which is not the case in ginseocostata. Lastly the present species 

 expands 14 nun. onh% as against 17 mm. in the other.

Genus SCH ISTOCOLPI A, new genus. 



An oft'shoot from Dysephynt Warren, characterized by an abnormal 

 structure of the hindwing of the male. The hind margin of the wing 

 is deeply excised along vein 5 for half the length, the sides of the 

 incision fringed; this is concealed on the under side by a broad fringe 

 of long silky hairs, rising from the base of the joint stem of veins 6 

 and 7 and curving along vein (5 to the end of the incision on hind 

 margin, the hairs decreasing in length suddenly; the course of vein 6 

 is curved, not straight; the hind margin is, besides, incurved from vein 

 7 to 4, where it is bluntly prominent, so that the general outline of 

 the wing appears irregular. 



The antennie of the male, as in Dt/sej>hj/ra, are fasciculate-ciliate. 



Type. — Schi'stocolpia crmita, new species.
