Mas. Fulvus, subtus testaceus ; caput bisulcatum, fasligio piano sub- 

 rhomboidati ; prothorax subcarinatus, margine poslico producto 

 subanyulata ; prosterni spina robu^ta, tonga, subacuta ; pedes postici 

 lestacei ; aloe anticee cinerece, basi fulva, fasciis nonnullis indeter- 

 minatis pallide fuscescentibus ; alee postica diaphanee^ apice 

 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. inamcenus. Antennae slender. Prothorax with a 

 slight keel and with the usual transverse impressed lines; hind border
