COLASPOSOMA.

<d • Head closely and rather strongly punctured ; clypeus 
strongly rugose at base, with an elongate tubercle at the middle of 
the latter ; surface strongly rugosely punctured ; antennae with dis- 
tinctly thickened terminal joints, basal joint metallic, following four 
or hve joints dark fulvous, rest blackish, terminal joint elongate, 
third rather longer than the fourth. Thorax more than twice as 
broad as long, scarcely narrowed anteriorly, sides rounded ; surface 
finely and closely punctured, punctures slightly larger and partly 
confluent at the sides, those on the disc finer than the punctures 
on the head. Scutellum very broad, half as broad again as long. 
Elytra about two and a half times longer than the thorax, with a 
distinct but short depression below the base, interior of depression 
strongly punctured, rest of surface very finely punctured in irre- 
gular rows, these rather distantly placed at base but closer and 
irregular towards apex. The male organ is strongly curved, very 
gradually narrowed anteriorly, the upper cavity is elongate and 
bounded by an acute ridge or edge. 
5 . The elytra more closely and strongly punctured although 
comparatively finely so, but the punctures are larger than those 
on the thorax ; the rugosities at the sides of the elytra are scarcely 
more strongly developed than those in the male.

Hob. Bengal ; Pondicherry ; Bangalore ; Assam ; Burma ; 
Ceylon ; Sumatra. 
Specimens from Ceylon are generally metallic cupreous in colour. 
The species seems closely allied to C. splenclidum, Eabr., which is 
a doubtful species, but according to Baly an insect of 7 mm. in 
length. This author in his description of Eabricius’s supposed 
species makes no mention of the sex he had before him, without 
which no recognition of a species in this genus is certain. One 
of the principal characters of distinction is the black abdomen. I 
cannot find sufficient differences between the type from Sumatra 
and the Indian specimens to warrant their separation.

Metallic green or blue ; antennae, palpi and tarsi black. 
. Head finely and remotely punctured, finely strigose above 
the eves : clypeus with a deep fovea at base ; basal joint of antennae 
metallic blue or green, terminal five joints slightly thickened, louger 
than broad, third aud fourth equal. Thorax more than twice as 
broad as long, sides strongly rounded, disc evenly and finely punc- 
tured. Elytra with short depression below base, rugose within
