COLASPOSOMA.

but the rugosities are confined to the depression and do not extend 
lower down ; in nearly all specimens the basal joints of the 
antennas are purplish. 
Length 5|-7 mm. 
Bab. Southern India : Nilgiris ; Pondicherry; Travancore. 
Differs from C. robustum , Jae. in its smaller size, stronger and 
more close puncturation of the head, the short, thick, terminal 
joints of the antennas, and the larger non-aciculate punctures of 
the elytra and thorax. Male organ strongly curved, somewhat 
suddenly narrowed anteriorly, apex acute, upper cavity ovate, 
bounded in front by a narrow smooth space.

Greenish-cupreous ; antennas and labrum fulvous ; abdomen 
black. 
<4 . Head remotely and rather finely punctured ; clypeus scarcely 
separated from the face; antennae with the terminal joints dis- 
tinctly thickened, the latter black or fulvous, basal joints always 
fulvous. Thorax rather more than twice as broad as long, not 
narrowed anteriorly, lateral margins narrowly refiexed, punctures 
like those on the head and similarly arranged except at the sides, 
where the puncturation is closer. Scutellum finely punctured. 
Elytra rather more strongly punctured than the thorax, punctu- 
ration arranged in close rather regular rows, basal depression 
generally obsolete. Breast metallic greenish ; legs more or less 
feneous ; femora sometimes fulvous at base. 
$ . Elytra with feeble basal depression, lateral interstices only 
slightly rugose, extending beyond the middle, more strongly 
marked near the margins. 
Length 4-5 mm. 
Sab. Bengal ; Malacca. 
A female specimen, kindly sent me by M. Clavareau and named 
by Lefevre, proves his species to be identical with my C . planifrons. 
The author's description applies equally well to many others, as 
no details of distinction are given. The present species is charac- 
terized by the remote puncturation of the head, the comparative 
strong punctures of the thorax, which have the interstices much 
wider than the punctures and the all but complete absence in the 
male of an elytral depression. 
The species is extremely close to C. asperatum , Lefev., and can 
scarcely be distinguished from it, although the author describes 
the head of the last-named species as “ densely punctured ” and 
of C. serratulum as finely and remotely so, but there is scarcely 
any difference in this respect in the specimens determined bv 
Lefevre and contained in my collection.
