strie effaced before reaching the apex, which is pretty thickly finely punctate; the inter- 
stices for the most part impunctate, but some with a few straggling, almost imperceptible 
irregular punctures; exterior apical angles rounded, sutural angles right-angled. Abdo- 
men more finely and closely punctate than the rest of the body, with large depressions 
on each side of the last three segments both above and below ; dorsal exposed portion of 
the abdomen about the length of the elytra. Underside finely punctate and slightly 
pubescent. Legs punctate. 
From Madagascar.

Very nearly allied to C. castaneus. It is, however, larger and throughout rather more 
coarsely punctate. The labrum is different—larger, more prominent, and prolonged 
instead of transverse, and is dull and more punctate; it has only a trace of the longi- 
tudinal smooth line diverging in front which we find in C. castaneus. The mandibles 
are larger, stronger, and more strongly toothed at the tip. "The head is much broader in 
front and more deeply punctate. The thorax is differently shaped: instead of being 
subquadrate it is subcordate, broadest in front, and the posterior angles more obtuse and 
reflexed. The scutellum is a little more punctate. The apex of the elytra has a narrow 
black margin. The head and thorax are very much enlarged and widened in the males. 
In other respects it is the same as C. castaneus. 
From Madagascar.

Habitat in Madagascaria. 
Elongate, narrow, slightly punctate and finely pubescent, nigro-piceous. Head, thorax, 
and scutellum somewhat shining, elytra and abdomen subopaque, the margins sub- 
ciliated. Head broad, finely punctate, with the epistome marked off by a semicircular 
line. Labrum small, rather projecting, flat, opaque, punctate. Thorax broadest in front, 
bisinuate in front, scarcely sinuate behind, depressed on the sides and at the posterior
