South American Eit7nolpidm. 497 



Chalcophana caruleipennis, sp. n. 



Fulvous, the antennte, apex of the tibise and the tarsi black, thorax 

 nearly impunctate, elytra strongly punctured in closely-approached 

 rows, metallic blue, the extreme apex fulvous. 



Fern. Elytra with deep basal depression, more finely punctured in 

 double rows, the sides with three costse, the inner and outer one 

 abbreviated anteriorly. 



Length 7-8 millim. 



Mas. Head nearly impunctate, the clypeus swollen, with a few 

 very minute punctures, antennae black, the lower three joints more 

 or less fulvous below (the last three joints wanting) ; thorax scarcely 

 twice as broad as long, the sides rounded, the angles dentiform but 

 scarcely produced, the surface with a few extremely fine punctures, 

 scutellum fulvous ; elytra with a distinct but not very deep depression 

 below the base, bounded laterally by a short costa which begins at 

 the shoulders, the surface rather strongly punctured in closely 

 approached and fairly regular rows which show a slight tendency to 

 run double, the punctures within the depression stronger than the 

 others, the ground colour a bluish-green as well as the epipleura% the 

 extreme apex fulvous ; below, the femora and the basal portion of 

 the tibiaa fulvous, the apex of the latter and the tarsi black, this 

 colour extending at the anterior tibial nearly to the base. 



Hah Colombia, S. Innes. 



The female of this species is larger and broader, the 

 thorax is twice as broad as long, and the anterior angles 

 are produced outwards, the elytra are geminate punctate- 

 striate with a deep basal depression and have four costee 

 at the sides ; of these, the longest and most strongly- 

 marked extends from the shoulders to the middle, two 

 others are placed near the sides at the lower portion, and 

 the fourth is placed at the middle and precedes the 

 humeral costa, it is very short, the epipleurse in the same 

 sex are likewise fulvous; but in everything else it agrees 

 with the male. 



Amongst the species which have similarly coloured tibia) 

 and tarsi may be mentioned G. consohrina, Har., G, effulgens, 

 Erichs., G. viridi'pennis, Germ., and G. limhalis, Har. Of 

 these the first named has distinctly geminate punctate 

 elytra, and the female has no elytral costge, the second has 

 no elytral fulvous apex, the third named is of different 

 coloration and has only the tarsi black ; G. limhalis differs 

 in having the sides of the thorax sub-angulate ; G. eximia,
