rostscutellum snioofli, the sides aciculated-stiiatccl. Pro- 

 jileuro? rugose above, tlie rest stoutly obliquely striated, the 

 strisp intermixing more or less; the meso- and nieta- 

 pleuia" closely coarsely reticulated-punctured. Tibia; sparsely, 

 the tarsi closely spinose. Palpi and mandibles black, the 

 former covered witli white pubescence. Head, thorax, and 

 legs densely covered with white pubescence. The front is 

 deeply depressed from the eyes and is strongly, closely, 

 transversely striated. 



This sjiecies is not unlike C. luculentus, Cam. ; the two 

 may be separated thus : — 



Apical keel on metauotum interrupted in the middle ; 

 four anterior femora not lined with black ; the 

 three middle joints of hind tarsi not yellow .... hiculentus, Cam. 



Apical keel on metanotum complete ; the four ante- 

 rior femora broadly lined witli black; the three 

 middle joints of hind tarsi yellow Binyhami. 



C. Bingliami i.s a more slenderly built species than lucu- 

 lentus ; the front is more deeply depressed and is more 

 distinctly transversely striated; the scutellum is more promi- 

 nent and has the sculpture rougher and more irregular. 



The male of Binghami has the inner orbits more broadly 

 yellow than in the female; it differs further in the face 

 having in the middle of the top above a yellow mark, longer 

 than wide and narrowly projecting at the sides above ; the 

 clypeus and mandibles are for the greater part yellow, as are 

 also the greater part of the anterior coxee and trochanters ; 

 the middle coxa3 and trochanters are yellow on the outer side. 



C. luculentus has been taken by Col. Bingham at Darjiling, 

 7000 feet, in March.

Scutellum not much raised, quadrate, stoutly keeled 

 laterally to the top of the apical slope. Metanotum regularly 

 areolated ; the areola about two and a half times longer than 

 wide, rounded and slightly narrowed at the base, rounded 

 inwardly at the apex ; the lateral basal are?e confluent, the 

 petiolar area absent. Antennae distinctly dilated towards the 

 apex. Apex of clypeus broad, transverse. Apical tooth of 

 mandibles long, narrowed gradually towards the apex ; the 

 subapical tooth short, turned inwardly. Base of petiole 

 broader at the base than it is thick dorso-ventrally — broader
