so closely punctured as the thorax, the punctures arranged in 
irregular rows ; the interstices also very minutely punctured, 
transversely rugose at the sides, the rugosities assuming the 
shape of tubercles behind the middle near the lateral margin ( $ ). 
Underside and legs piceous, with a slight metallic gloss. 
Length 4-5 mm.

Very closely allied in sculpture to C. albovillosum, Duv., but 
without any pubescence and the punctures on the thorax and 
elytra still more numerous, finer and more evenly distributed ; 
the colour of the antennae also differs ; the scutellum is much 
smaller and scarcely punctured. The difference in the width of 
the thorax in the sexes is very great : in both this part has 
a distinct reflexed lateral margin, the latter is also subangulate 
behind the middle. 
As regards the male, the species is very difficult to distinguish 
from C. asperatum , Lefev., and may possibly be identical with 
it, but Lefevre’s description is too general for a more certain 
identification. 
Elytra strongly depressed below base. 
784. Colasposoma bicoloratum, sp. n. 
Dark violaceous ; elytra cupreous. 
Head closely punctured and strigose above the eyes ; base of 
clypeus rugose, with the usual tubercle ; labrurn black ; antennae 
long and slender, basal six joints purplish, rest black, terminal 
joints elongate, only slightly thickened. Thorax more than 
twice as broad as long, sides very strongly rounded, punctures 
finer than those on the head, very closely placed and evenly 
distributed, not deeper and more distantly arranged at the sides. 
Scutellum purplish-blue, with a few punctures. Elytra wider at 
base than the thorax, punctures as fine as those on the thorax, 
arranged in rows ; sides below shoulders with a distinct transverse 
depression, more deeply punctured aud rugose. Legs violaceous 
blue; anterior tibiie of male strongly widened at the apex. 
Length 8 mm.

Oloselv allied in coloration to C. pretiosum, Baly, but the 
sculpture quite different, that of the thorax less closely placed, of 
the elytra arranged in rows, much finer ; the interstices not finely 
rugose.
