CHALCOPHANA. 163 



scutellum rufous ; elytra dark violaceous blue, the apex only narrowly rufous, the sides with three or four 

 more or less distinct costse and a rather deep depression below the base ; the interstices finely geminate 

 punctate-striate, simply punctate -striate towards the apex. 



Hab. Guatemala, Zapote, El Tumbador {Champion). 



Of this species four female specimens were obtained by Mr. Champion. On account 

 of the colour of the elytra the insect can only be compared to C. wagneri, from 

 which it is distinguished by its narrower shape, the colour of its antennae and legs, 

 and the closely and finely punctured thorax.

Since the publication of my species I have received sufficient material to come to 

 the conclusion that the latter is identical with v. Harold's insect. The size is given by 

 this author as nine millimetres ; my insects vary from two to three lines only ; specimens 

 of such large size as v. Harold gives I have not seen. The species is entirely of reddish- 

 brown colour ; and the elytra are costate throughout, less distinctly so in the male than 

 in the female ; the thorax is nearly impunctate on the disk. The specimens from Chiriqui 

 are partly almost black below, and the first four joints of the antennae are rufous, instead 

 of three joints as given by v. Harold; but in all other respects they agree with the 

 description, which seems to me to be that of the female. Male specimens which I take 

 to belong to this species are smaller; the head has a distinct elongate triangular 

 depression between the eyes ; and the punctuation of the elytra is,- except at the middle, 

 nearly simply punctate-striate, the sides have only one or two ill-defined costse ; and 

 the interspaces there are coarsely and irregularly punctate. 



19. Chalcophana rufipennis. (Tab. VIII. fig. 17.) 



Chalcophana rufipennis, Jacoby, P. Z. S. 1878, p. 144 \ 



Hab. Costa Eica, Volcan de Irazu 1 (Rogers) ; Panama, Volcan de Chiriqui, 2000 to 

 3000 feet (Champion). 



This very distinct species is at once separated from the two preceding ones by its 

 black underside and the light flavous legs and antennae ; the elytra are more or less 

 rufous and closely punctate-striate, with three lateral costae. The male is unknown ; but 

 a single female specimen has lately been received from Chiriqui, which is much 

 larger than the Costa-Eica insect, and differs in the colour of the antennas and legs, 

 which are fulvous instead of light flavous ; but it agrees in all other respects.
