narrowed on the inner side and the whole of the fifth 

 segment, yellow. Legs covered with a whitish pubescence ; 

 clear yellow ; the coxae and femora to near the apex, and a 

 line on the tibiae, black ; the outer spur of hind tibiae nearly 

 as long as the metatarsus, broadly dilated. The recurrent 

 nervure is received in the middle of the radial cellule. 



May be known from C. buddha by there being no 

 shining fovea along the inner orbits of the eyes ; by the 

 scutellum being longitudinally striolated ; by the petiole 

 and second abdominal segment being marked with yellow, 

 and by the fuscous wings. Length 8 mm.

Head shining, finely punctured, less strongly on the 

 vertex than on the front ; there is a minute furrow between

 black at extreme apex. Thorax shining, more strongly 

 punctured than the front, shining ; shortly pilose ; the 

 sternum densely covered with short pale pubescence ; meso- 

 pleural furrow wide, crenulated ; there is a small round 

 fovea on the posterior lower edge of the mesopleurae. 

 Pronotum above distinctly raised, transverse, the sides of 

 the raised part oblique ; the hinder part of the prothorax 

 separated by a wide and deep depression from the anterior. 

 Scutellum finely punctured, the sides narrowed behind, 

 margined ; the basal depression crenulated. Median seg-
