latiori, sat crebre minus subtiliter nee profunde punctulato, 

 antice bisinuato, a basi antrorsura (superne viso) arcuatim 

 angustato, basi media sublobata, angulis anticis obtusis

 G. cupripennis) seriatim punctulatis, interstitiis planis (quam 

 cupripennis magis) subtiliter sparsius punctulatis ; prosterno 

 medio carinato ; metasterno et episternis sparsim subtilissime 

 punctulatis, illo ad latera oblique rugato ; abdomine fere ut 

 metasternum punctulato et distincte rugato ; femoribus anticis

This is a somewhat difficult species to place in my tabulation, 

 owing to its having slight (but only slight) indications of ocular 

 sulci and elytral interstices punctured somewhat less strongly 

 than in the allies of cupripennis, but decidedly more strongly 

 than in Icetiis, so that it appears somewhat interaiediate ; the 

 sides of its prothorax, moreover, viewed from above, are less 

 strongly arcuate than in most species in which the form of the 

 prothorax is what I have called "normal," so that it tends a 

 little towards the group with their prothorax trapezoidal. In 

 colouring and puncturation of the prothorax and elytral series it 

 resembles a very bright specimen of C. cicpripennis but its head 

 is evenly punctured, its prothorax more narrowed in front, its 

 eyes more approximate, its antennae shorter, its elytral interstices 

 more finely punctured, and the basal joint of its hind tarsi much 

 shorter. It also resembles fervens, Germ., but differs from that 

 species inter alia by its black head, prothorax and undersurface, its 

 more approximate eyes, much shorter antennae, and the much 

 shorter basal joint of its hind tarsi. The outline curve of its 

 elytra (viewed from the side) is moderately strong, with its 

 summit a little in front of the middle. It is not at all like 

 G. rugosipennis, MacL, next to which the exigencies of tabulation 

 require it to be placed.
