CHALCOPHANA. 161 



narrow fulvous band extends across the elytra, as in the case of C. cincta. The 

 specimen figured is a female variety from La Parada, which I cannot distinguish 

 from the specimens from Chiriqui, although the thorax is much more closely 

 punctured. 



14. Chalcophana hybrida. 



Oblong, narrowed behind, rufous or fulvous; thorax distantly punctured; elytra metallic green, strongly 

 geminate punctate-striate, their margin and apex fulvous ; apex of the tibise and the tarsi black. 



$ . Larger, the elytra more finely punctured ; the sides with three more or less distinct costse. 



Length 2-3 lines. 



Head with a few very fine punctures and a more or less distinctly impressed longitudinal groove ; antennae 

 black, the first four joints fulvous ; thorax transverse, the anterior angles produced into a short tooth ; 

 surface very remotely but distinctly punctured ; elytra with a distinct transverse depression below the 

 base, strongly and closely subgeminate punctate, the interstices not subrugose at the anterior portion, 

 metallic green, the lateral margin and the apex narrowly fulvous. 



Hab. Guatemala, Capetillo (Champion). 



Again similarly coloured to C. germari and the allied species, but evidently a distinct 

 one, as the following differences will suffice to show : — The present species, if the males 

 are compared with those of C. germari, is of a more pointed shape posteriorly, nar- 

 rower and less convex ; the antennae are more slender, and their terminal joints less 

 robust and shortened ; the thorax is more sparingly and less deeply punctured, and the 

 elytra less coarsely punctate, the interstices smooth and not subrugose anteriorly. The 

 female may be distinguished from that of C. germari by the shining and very sparingly 

 punctured thorax, the more finely geminate punctate-striate elytra, and the costse of the 

 latter running in a curved line, and not in a straight one as in the former insect. It is 

 absolutely necessary in the descriptions of these closely allied insects to mention the 

 differences between the sexes, or, where both are not known, to indicate the sex 

 before one. V. Harold has omitted this in several instances ; and I am in these cases 

 not sure with which of his species those described here are to be compared. The present 

 species was received in abundance from Capetillo only. 



15. Chalcophana obscura. 



Ovate, short, obscure piceous or dark brown below ; head and thorax brown or piceous, distinctly punctured ; 

 elytra dark violaceous blue, finely subgeminate punctate-striate. 



Length 3 lines. 



Head with a few fine punctures at the vertex and an obsolete depression between the eyes ; clypeus triangular, 

 distinctly limited behind by two smooth raised spaces ; antennae bluish black, the first three joints obscure 

 piceous or brown ; thorax not more than twice as broad as long, piceous or dark brown, its surface very 

 irregularly covered with small and larger punctures; scutellum black; elytra somewhat irregularly 

 geminate punctate-striate, the punctures much more finely impressed and more regularly arranged in 

 double lines near the apex than at the base ; underside and legs brown or piceous, with a more or less 

 distinct purplish reflection. Female unknown.
