Black ; abdomen immaculate ; palpi pale ; mandibles testaceous 

 in tlie middle ; coxae and upper trochanters black ; legs rufo- 

 testaceous, fore femora at the base, 4 posterior entirely except the 

 apex, and apical half of hind tibia;, black, these last with an obso-

 "Wings subfumato-hyaline, darker towards the ajDex, stigma and 

 nervures fuscous, costa, parastigma, praebrachial nervure, and 

 sqtiamulae testaceous ; radial areolet broader than the stigma, 3d 

 abscissa of the radius straight, radius of the hind wings straight, 

 except its basal curvature. Body not shining, thinly beset with 

 whitish hairs, which become thicker on the face, so as almost to 

 conceal the surface, and form 2 tufts at the angles of the meta- 

 thorax. Head minutely subrugulose, almost coriaceous; vertex 

 transverse, contracted behind the eyes ; cheeks not dilated ; fi'ontal 

 fovea ample, shallow, not shining, nor geminated. Antenna; S'

Very like C. cornilus, sp. 6, but differing in the 

 antennae, the pubescence of the face, the testaceous
