obsolete at apex ; interstices feebly convex, finely but distinctly 
punctured ; shoulders with an ovate spot, another larger, triangular 
spot touching base, near scutellum ; posterior band nearly touching 
lateral margins and slightly curved upwards there, apparently 
consisting of two united spots. Pygidiutn finely and closely 
punctured ; prosternum with anterior margin produced at middle, 
posterior angles produced into long points.” ( Suffricin .) 
Length 3 mm. 
Hab. Southern India. 
In colour similar to 0. vahli , but with differently sculptured 
elytra and long, pointed, posterior angles to the prosternum. 
Genus PACHYBRACHYS. 
Pachybrachys, Suffrian, Monogr., Linn. Ent. iii, 1848, p. Ill; Chapuis , 
Gen. Coleopt. x, 1874, p. 168. 
Type, P. hieroglyjphicus, Laich., from Europe. 
Range. All parts of the globe, principally developed in North 
and South America. 
Cylindrical, only moderately convex. Antennae filiform, terminal 
joints very feebly widened. Thorax transverse, sides with a sub- 
marginal fine groove, anterior angles shortly dentate, posterior 
obtuse ; posterior margin with a narrow acute ridge, which is raised 
in front of scutellum. Scutellum divided into an anterior sub- 
quadrate and a posterior triangular portion. Elytra rather raised 
at base and round scutellum ; epipleurae invisible from above ; 
surface generally partly punctured in rows, rarely irregularly, with 
more or less prominent elongate pale costae or spots, the punctures 
dark. Prosternum not produced anteriorly for the reception of 
the parts of the mouth, the disc longitudinally concave, posterior 
margin produced into a more or less prominent lobe. 
The species of this genus can be distinguished from Crypto- 
cephalus proper by the different shape of the thorax and elytra, 
and the sculpture of the latter ; the thorax is much more 
transverse and less subcylindrical, and its angles are more pro- 
minent, not closely approximate to base of elytra. Only two 
Indian species are known.
