 pubescence, and also with fairly thickly-set pale yellow erect hairs.

 rounded but prominent ; mandibles with 6 teeth ; clypeus broad, 

 not carinate nor lobed, its anterior margin transverse, denticulate.

 with the pro- and mesonotum and the apical half more steeply 

 sloped, obliquely truncate ; legs comparatively long, the tibia? 

 compressed and longitudinally channeled. Node of pedicel very 

 thick, strongly biconvex and transverse above ; abdomen large and

M. Forel regards this and another form, which he has named 

 var. integer, as varieties of C. sericeus, Fabr. I have described 

 C. mendax from specimens in Mr. Wroughton's collection named, 

 I believe, by M. Forel, and it seems to me a good species. C. in- 

 teger, Forel, is unknown to me, but is described as very like 

 C. sericeus, except that the thorax is equally convex anteriorly and 

 posteriorly, with no emai-gination at the meso-metanotal suture. 

 It is variegated with brownish and ferruginous.
