thorax and elytra, the distinct costa on the latter near the 
margins, and the appendiculate not bilid claws ; the elytral 
punctures are not invisible near apex as Marshall states, but on 
the contrary quite distiuct. The sexes differ but little. 
Whether the metallic-green form with pubescence at the apex 
of the elytra and the reddish- cupreous underside is really a variety 
or a distinct species I cannot say. I cannot find any structural 
differences.

B . Dark blue or violaceous. Head rather remotely and 
strongly punctured, generally with a deep triangular cavity on the 
forehead ; clypeus separated by a deep transverse sulcus, liuely 
aud closely punctured, transverse; antennae bluish-black, reaching 
nearly to the middle of the elytra, basal six joints shining, the 
rest broadly dilated, opaque, third and fourth joints equal. Thorax 
about half as broad again as long, subquadrate, lateral margins 
very feebly rounded aud very slightly narrowed anteriorly ; 
surface very remotely and sparingly punctured, the punctures 
shallow, sides of thorax when seen from above rather strongly 
defiexed anteriorly. Scutellum smooth. Elytra parallel-sided 
and cylindrical with a deep transverse depression below the base, 
joined to another equally deep depression in front of the shoulders 
that extends to the basal margin ; surface rather finely, closely and 
regularly punctate-striate, punctures within the basal depressions 
stronger, the others much more distinctly marked than those on 
the thorax. Intermediate femora slightly dilated into a small tooth 
beneath. Claws appendiculate. 
5 . Elytra with an acute costa at the sides from before the 
middle to apex and a more obsolete and shorter costa near the 
lateral margins. 
Length 9-10 mm.

The above description is drawn up from the type of Eabricius 
in the Banksiau Collection in the British Museum. Marshall’s 
types of the synonyms as given above are likewise contained in 
the Museum collection and cannot be separated specifically ; but 
C. shepparcli, Baly, which is united by Marshall and Lefevre with 
C. nitidus , is in every respect a totally different species, while so 
far as the description of C. amoenus goes it agrees in every detail 
with Fabricius’s type.
