of the antennae, and the tibiae and tarsi of the legs on the outer 

 side yellowish red ; head, thorax and abdomen with sparse, very 

 short, white bristly hairs ; head and thorax coarsely striate, 

 the striae running into irregular reticulations in parts ; abdomen 

 more finely and regularly striate, the striae shallow ; the margins 

 of the head and thorax studded with minute irregular denticula- 

 tions. Head, along the occipital margin, as broad as long, the 

 sides of the head on the anterior third rounded, straightening 

 posteriorly ; the occiput slightly but widely emarginate, with the 

 lateral angles produced, dentate, a small tooth not very prominent 

 below the eye on each side of the head ; mandibles and clypeus as 

 in C. granulatus. Thorax : the pro-mesonotal shield very convex, 

 the sides straight, narrowing and rounded abruptly, posteriorly, 

 the anterior lateral angles not prominent ; meso-metanotal suture 

 not distinct ; the basal portion of the metanotum broader than 

 long ; the lateral metanotal spines somewhat short, horizontal, 

 directed backwards and slightly divergent ; sides and apical 

 portion of metanotum vertical, the latter slightly concave, 

 obscurely transversely striate. Pedicel short ; the nodes subequal, 

 somewhat globose, more coarsely and roughly sculptured than the 

 thorax or abdomen ; abdomen short, broadly oval, convex.

. Intense black ; the apex of the scape, the tibiae and tarsi of 

 the legs orange-red ; pilosity rather long, whitish in colour ; head, 

 thorax and pedicel very coarsely sculptured (more coarsely than in 

 any other species of the genus known to me) and rugose ; the 

 head and thorax covered with reticulations, which are raised and 

 tuberculous. Head as in U.granulatou, but proportionately larger, 

 with the tooth on the lateral margin of the head below the eye and 

 the spinous process on the posterior lateral margin of the head 

 larger arid more produced. Thorax with the sutures obsolete, and 

 the lateral spines on the posterior angles of the basal portion of the 

 metanotum modified into slightly produced rounded projecting 

 laminae. Pedicel with the nodes remarkably rugose; the 1st node 

 the longer, and longer than broad ; the 2nd node oval, truncated 

 in front and posteriorly ; abdomen as in C. granulatus. 



Length, $ 5'5 to nearly mm.
