third, fourth, sixth, eighth, and following joints clear pale testa- 
ceous. The disk of the thorax has several olive-brown spots. 
The elytra are of a reddish-tawny hue, with tawny-ashy pile ; 
they are spotted as in the typical O. cinerascens, but instead of 
a waved fascia behind the middle, they have simply a short 
oblique stripe on the disk of each. Body beneath and legs 
pale testaceous j knees, tips of tibiae, and middle of the tarsi 
dusky. 
O. cinerascens resembles much in markings a small allied 
species from Rio Janeiro, which is as yet unnamed in collec- 
tions *.
