194 THE ENTOMOLOGIST. 



Head sparingly, irregularly, but distinctly punctured, fulvous, the 

 vertex with a more or less distinct greenish black spot ; clypeus sub- 

 quadrate, finely punctured ; antennae scarcely extending to the middle 

 of the elytra, fuscous or black, the lower four joints fulvous, the 

 third and the following four joints elongate, equal, the terminal ones 

 shorter; thorax nearly twice as broad as long, the sides nearly straight, 

 oblique, the angles tuberculiform, the disc with a more or less distinct 

 lateral fovea, very sparingly and irregularly impressed with larger and 

 smaller punctures, dark fulvous, the sides marked with piceous, ill- 

 defined ; scutellum fulvous ; elytra reddish fulvous with metallic pale 

 green gloss, very elongate, the apex of each concave-emarginate, the 

 surface closely and very strongly punctured, the punctures near the 

 suture more or less geminate and separated by raised longitudinal 

 interspaces which assume the shape of strongly raised costfe at the 

 sides, of which two below the shoulders are very highly raised and 

 continued to the apex, the shoulders themselves are likewise strongly 

 raised and prominent, and have another short costa below near the 

 lateral margin ; breast and abdomen black ; legs fulvous ; prosternum 

 very deeply bilobed. 



Hah. — Bolivia. 



This is one of the most distinct species of the genus, which 

 may be best compared with C. quadricostata, Jac. (Biolog. Cent. 

 Amer.), on account of the emarginate elytral apex ; the present 

 insect is, however, very elongate, and has the entire under side 

 black, while the legs and tarsi are fulvous. The two specimens 

 contained in my collection are evidently females, and the other 

 sex is probably devoid of the elytral costfe. 



Chalcophana vmiDi-BASALis, n. sp. 



Elongate, pale fulvous; the antennas, tibiae, and tarsi black; thorax 

 sparingly punctured ; elytra strongly and closely punctate-striate, pale 

 fulvous, gradually shading into metallic green at the base. Length 

 3-4 lines. 



^ . Head rather strongly and closely punctured, dark fulvous ; 

 clypeus similarly sculptured ; labrum flavous ; antennae extending 

 beyond the middle of the elytra, black, robust, the third joint one half 

 longer than the second one, but much shorter than the fourth joint; 

 thorax twice as broad as long, the sides rounded, the angles tuberculate, 

 the surface with larger and smaller punctures, sparingly and irregularly 

 distributed ; elytra strongly punctured near the base, the punctures 

 gradually diminishing in size and arranged in closely approached rows, 

 the basal portion and the suture metallic green, the rest of the surface 

 pale fulvous, both colours gradually blendmg before the middle; under 

 side and the femora pale fulvous ; the tibia3 and tarsi nearly black. 



2 . Larger ; the elytra with two or three short costa3 at the sides 

 below the shoulders. 



Ilah. — Bolivia. 



In this species, of which I possess six specimens, the metallic 

 green colour of the elytra is confined to the base only, although
