 rhomboidali ; prothorax subcarinatus, margine poslico producto 

 subangulato ; proslerni spina robusta, longa, subacuta ; pedes postici

 cinerete. 



Male. Tawny, testaceous beneath. Head short; vertex with two 

 slender furrows between the eyes; tip flat, subrhomboidal ; front in 

 structure like that of C. inamoenus. Antennas slender. Prothorax with a
