Oval, very convex, shining, aeneous or greenish-aeneous 

 above, aeneo-piceous beneath, the antennas and legs in great 

 part piceous; somewhat thickly clothed with long, erect, 

 bristly, brownish hairs (all easily abraded), the under suiface 

 and legs also pubescent ; the head and prothorax rather

 Prothorax rapidly narrowing from the base forward, the sides

 Scutellum wanting. Elytra moderately long, rapidly, arcu-

Described Irom a perfect male captured by Mr/Cameron in 

 Dec. 1914. Two others, imperfect and abraded (? ??), 

 found in the Falklands in i860, and presented by Mr. Havers 

 to the British Museum in lb73, seem to belong to the same 

 species. The unique type of the genus, C. $olox x is a larger 

 and broader insect (length 3|, breadth 2\ mm.), and much
