cephalic horn is short tmd vertical, the shape of the prothorax is the 

 same, and the granules are equally closely packed ; the geminate 

 striae of the elytra, however, are not so deeply punctate, and in the 

 intervals the minute tubercles of the double series are set more 

 closely to one another. It is very probable that in some examples 

 the three apical testaceous patches on the elytra coalesce and form 

 an apical band.

Bronze black, dark bronze, or bronze, moderately shining, antennae 

 flavescent; clypeus semicircular, slightly blunted at tip, but not 

 emarginate, transversely plicate, vertex smooth, frontal carina very 

 distinct ; prothorax not much convex, moderately ampliate laterally 

 and with the median part of the base rounded, covered with equally 

 distant punctures set moderately close to one another, and having in 

 the posterior part a slight longitudinal impressed line ; elytra some- 

 what elongate and not very ovate, finely geminato-striate, wdth the 

 intervals slightly raised near the base, and filled with three series of 

 briefly setigerous punctures, second interval very slightly broader 

 than the third ; pygidium closely punctate, not very pubescent, sub- 

 aculeate at tip, smooth in the centre, and having a median longi- 

 tudinal impressed line. 



Male : Cephalic horn short, conical in the great development, or 

 flattened, triangular, not as high as the anterior truncate part of the 

 prothorax which is not excavate but bears two small, closely set 

 median tubercles at the top ; inner part of anterior tibiae briefly 

 spinose at tip. In the small development the cephalic horn and the 

 thoracic tubercles are rudimentary. 



Female : Vertex witli a median, transverse ridge, anterior part of 

 prothorax sloping normally, but having close to the anterior margin 

 a short, slightly raised, transverse carina which, however, is often 

 indistinct. 



Length, 6-7 mm. ; width 3^-4 mm.
