submarginal one not reaching the apex. Epipleiira partly dark. 

 Body beneath pale, femora pale with narrow dark stripe, hind femora 

 dark at apex, tibiae and tarsi dark. Length 7 to 8.6 mm., width 3.8 

 to 4.5 mm. 



Type: In BM, from Perii. 



Other localities: Peru: Ciimbare, four specimens, Reyes, one 

 specimen, all in MCZ (Bowditch collection); Rio Huallaga, Rio 

 Morona, Rio Santiago, and Iquitos, five specimens, all collected by 

 H. Bassler, in AMNH. 



Remarks: As in the case of D. nigrojascia.ta (Jacoby) this species 

 clearly belongs in the genus Disonycha by reason of ha\dng eyes 

 only slightly emarginate and not truly reniform, in this respect not 

 being any difi'erent from others of the genus. It differs from D. 

 nigrofasciata in having a paler head and not bicolored antennae.

Type: Female, in BM, from "St. Paulo"; paratype, female, USNM 

 61829, without locality label. 



Remarks: Only two specimens, both females, are at hand, but 

 these seem quite distinct from the rest of the nigrofasciata gi-oup. 

 They have in common with the others the large size, short, wide pro- 

 thorax, broad elytra, and the coloration of the legs, but differ from
