Hah. Upper Amazons, Ega. 



Two specimens of this curiously-marked species are 

 contained in my collection, both belonging apparently to 

 the female sex. 



Chalcopliana hrevis, sp. n. 



Broadly ovate, fulvous, tlie terminal seven joints of the antennte 

 black, thorax finely and rather closely punctured, elytra greenish- 

 cupreous, without depression, closely and rather finely punctate- 

 striate. 



Length 6 millim. 



Mas. Of rather short and convex shape, the head closely punctured 

 at the vertex, with a distinct longitudinal groove, frontal callosities 

 bounded behind by a transverse groove, clypeus nearly impunctate, 

 labrum and palpi fulvous, antennae fulvous, the intermediate joints 

 more or less piceous ; thorax about one-half broader than long, rather 

 strongly narrowed anteriorl}^, the anterior angles produced, the sur- 

 face finely and irregularly punctured, the punctures of unequal size, 

 scutellum fulvous ; elytra without basal depression, very convex, of 

 a brassy greenish colour, finely punctured in closely ajjproached, 

 semi-regular rows, the sides (in the female) with an indication of a 

 short costa below the shoulders ; the epipleuraj, the underside and

Rab. Colombia. 



Allied to C. landolti, Lef., and G. 2^2cncticoUis, Lef., 

 likewise from Colombia, but the elytra in both sexes with- 

 out basal depression and costa; (in the female tliere is only 

 an indication of a short costa below the shoulders). C. 

 siiavis, Har., must be another closely allied species, but is 

 larger, and the antennae have only the basal two joints 

 fulvous, the rest black, the apex of the elytra is likewise 

 described as ferrusinous.
