CCENOCHILUS CALCARATUS, Westw., 



Thesaur. Entomol., p. 39, pi. xii., fig. 3. 

 Male : Piceous black, sometimes piceous red, moderately shiny on 

 the upper side ; clypeus and head sub-foveolate punctate, the punc- 

 tures almost contiguous and each bearing a minute, greyish hair, 

 anterior margin of clypeus fairly deeply sinuate ; prothorax nearly 

 orbicular, covered with closely set, round, fairly deep punctures 

 separated by a smooth interval narrower than their own diameter in 

 the anterior part, but nearly equal in the posterior where there is a 

 short, median, very shallow longitudinal impressed line and two 

 narrow, transverse impressions alongside the basal margin ; scutellum 

 irregularly punctate, sub-tectiform in the posterior part ; elytra not 

 broader at the base than across the median part of the prothorax, 

 nearly parallel, very elongated, the suture is sub-carinate, and there 

 are on each side two somewhat wide, little raised, yet distinct costae 

 separated by a somewhat broad stria, and two more, one reaching 

 from near the humeral callus to about one-fourth of the length, and 

 the other, which is nearly equally long, is situated above the lateral, 

 the surface is covered with elongated, moderately closely set but 

 non-contiguous, and non-cicatricose punctures ; pygidium vertical, 

 finely aciculated and very briefly pubescent, except along the margin 

 where the hairs are long and fulvous ; abdomen freely punctate ; 

 pectus and inner part of femora densely pubescent ; inner part of 

 tibiye also pubescent, hind ones short, and with the terminal inner 

 part produced into a long, subarcuate tooth directed inwardly, broad 

 at base and sharp at apex, and longer and much more robust than 

 the inner spur which is also very long.
