One male. Very near C. cirratus and C. rufocinctus, bnt with a smaller tuft of 

 hairs on the hind tibiae ( 6 ), the pro thorax parallel-sided at the base and with a

, sparsely punctured basal depression, the rufous markings differently shaped.

<?. Elongate-oval, broad, rather convex, opaque above, somewhat shining and pruinose beneath; black, the 

 prothorax in great part (the two large, coalescent spots at the base, the lanciform median spot, and 

 the short tubulate anterior lobe, black), and the elytra with the base very narrowly and an outwardly- 

 dilated submedian fascia (these markings connected along the outer margin), rufous. Eostrum very 

 stout, curved, about two-thirds the length of the prothorax, with a few minute scattered punctures, 



■ 



smooth at the tip, sulcate beneath, the basal portion also sharply sulcate above to the deep oblong frontal 



, Prothorax a little broader than long, rounded at the sides, gradually narrowed to the coarsely- 

 punctured tubulate anterior portion, bisinuate at the base, the disc excavate and coarsely punctate in 



the middle posteriorly and also with a few scattered punctures along the centre. Scutellum elongate- 

 triangular, somewhat concave. Elytra wider than the prothorax, oblong-cordate ; deeply striate, the 

 striae with rather fine scattered punctures, the interstices smooth and convex. Pygidium slightly 

 flattened, sparsely punctate and fulvo-pilose, the hairs tending to form a median crest and a fringe along 



■ 



the apical margin. Beneath closely punctate, the broad ventral excavation included, the fifth segment 

 with a large space at the apex set with long erect fulvous hairs. Eemora and tibiae ciliate, the tibiae 

 sinuate within, the posterior pair with an oblique matted tuft of much longer and coarser hairs at the 

 middle. 



Length 21*, breadth 8i millim.

One specimen. Larger and broader than C. rufocinctus, the basal depression of the 

 prothorax shallower and less coarsely punctate, the strise more finely punctate, the 

 markings of the upper surface differently shaped. The male-characters are similar. 



T ^e ventral depression is closely punctate, as in one of the five examples here referred

cJ . Yentral excavation broad and shallow ; fifth, segment with a large rounded space thickly clothed with 

 long, coarse, erect, fulvous hairs; pygidium fulvo-pilose and subcristate at the tip; femora strongly 



towards the base beneath ; tibiae sinuate and set with short, curled, fulvous hairs along their 





inner edge.

9 • Rostrum a little more slender ; ventral excavation shallower ; fifth segment with two small tufts of 



^r^ 



fulvous hair at the apex : anterior and intermediate femora with a small tuft of long fulvous hairs at the 

 base, similar to that on the coxae.
