apicali, metatarsisque intermediis posticisque, apice excepto, albo- 
flavidis ; alis hyalinis, venis fuscis ; mesonoto antice transverse 
striato, postice punctato. 
Long. 11 mm. 
9. Clypeus with a median carina, bluntly pointed at the 
apex, and clothed with close silver pubescence; mandibles 
tridentate, the middle tooth much longer than either the 
upper or lower. Eyes separated at the base of the clypeus 
by a distance equal to about one-third of the length of the 
scape, the facets in front very large. Head rather broader 
than the thorax, shining, minutely punctured, more closely 
on the front than on the vertex. Ocelli in a broad triangle ; 
the posterior pair much further from each other than from 
the anterior one, a little further from the eyes than from each 
other, and at least half as far again from the hind margin of 
the head as from each other. Pronotum transverse, almost 
smooth ; mesonotum closely transversely striated on the ante- 
rior half ; the posterior half finely punctured, with oblique 
strize on the sides. Scutellum and pleure finely punctured ; 
basal area of the median segment longitudinally striated. 
Abdomen shining, minutely punctured, pygidial area long 
and narrow. First and second abscisse of the radius sub- 
equal; recurrent nervure received shortly before the apex of 
the cubital cell.

This belongs to the group of C. fossorius, L., and C. chry- 
sites, Kohl, but is very distinct in the beautiful steel-blue 
colour, the less robust form, and the reduced size and pale 
colour of the markings. The sculpture of the mesonotum is 
similar to that of C. chrysites, but is stronger than in that 
species. Superficially this species resembles Gorytes ceru- 
lescens, Turn., the colouring in both species being unique in 
the genus.
