A most beautiful species of this curious genus, distinguished from 
all others by the metallic uniform colour of the elytra. 
One example, from Pebas, Upper Amazons.

In the form of the head, gradually and rectilinearly narrowed 
behind the eyes, this species resembles C. Batesii, Chaud., but the 
thorax is much narrower, aud is distinguished by being broadest about 
the middle, and gradually narrowing both before and behind. The 
interstices of the elytra are rather convex, and the large setigerous 
punctures unusually well marked. It is, apparently, most closely 
allied to C. Drapiezii of Gory, in which, however, the head and thorax 
are of a reddish colour. 
Taken at Ega. 
CrENODACTYLA GLABRATA, n. sp.—O. Chevrolatii similis, capite 
post oculos thoraceque longioribus, prosterni episternis wmnpunctatis ; 
migerrima, nitida, thorace rufo impunctato, antennis (basi obscuris) 
femoribus basi, trochanteribus, metasternt medio tarsisque rufescentibus ; 
elytris fortiter punctato striatis, interstitiis subplanis. 
Long. 5 lin. 2 exempl. 
Distinguished from C. Chevrolatii by the more intense black colour 
of the head and elytra, besides its black legs and impunctate polished 
thorax and prothoracic episterna. 
Apparently not uncommon on the banks of the Ucayali, whence 
Mr. Edw. Bartlett brought a considerable number. 0. brasiliensis, 
Lucas, from the same locality, differs by its red legs and black knees.
