the base than the thorax, not deeply but distinctly transversely 
depressed below the base, punctured in very closely approximate 
rows, the punctures rather stronger than those on the thorax. 
Length 7-8 mm. 
Hob. Burma ; Malay Peninsula 
A handsome and easily recognized species closely resembling in 
coloration Colasposoma pretiosum , Baly, from which the much 
more subcylindrical thorax and the structural characters of Chry- 
sochus at once separate it. 
886. Chrysochus moulioti, Baly, Joum. Eat. ii, 1864, p. 223. 
Violaceous or green ; a trigonal patch before the middle of the 
elytra and the lateral margins purplish ; labrum and basal joints 
of antennae fulvous. 
Subquadrate-ovate. Head rather closely and strongly punctured, 
strigose above the eyes, a deep central elongate cavity between 
the eyes ; antennae extending below the base of the elvtra, basal 
joint metallic blue or green, following three joints fulvous, the 
rest black, slightly widened, longer than broad, third joint longer 
than the second. Thorax twice as broad as long, transversely 
subquadrate, lateral margins straight at base, feebly rounded in 
front, the surface closely punctured like the head. Seutellum 
subquadrafce, sparingly punctured. Elytra with a very shallow 
depression below the base, very closely punctured in somewhat 
regular rows, punctures of the same size as those on the thorax, 
sometimes finer on the posterior portions of the elytra, the 
interior of the depression slightly more strongly punctured and 
with a purplish transverse, trigonal patch, not quite extending to 
the suture. Underside and legs blue or green. Prosternum very 
broad. Claws bifid. 
Length 9-91 mm. 
Hah. Burma : Tbarawaddy ; Siam : Tonkin. 
The purplish elytral patch can only be distinctly seen in the 
green specimens ; in those of violaceous tint is is only just indicated 
by a slightly darker colour of the corresponding part of the 
eiytra. In spite of some slight differences in the puncturation I 
cannot separate the Burmese specimens from those from Siam. 
Group END 0 CEPHAL1NI. 
Oblong or subovate, glabrous above ; antennaj filiform or with 
widened terminal joints ; eyes not surrounded by sulci. Thorax 
transverse with distinct lateral margins ; tibiae not emarginate at 
apex. Claws appendiculate. Prosternum oblong ; anterior margin 
of thoracic episternum convex. 
Three genera of this group occur in India, to which, though 
widely divergent in general appearance, the above structural 
details apply.
