the antennae with a few short spines behind ; first joint equal in 

 length to the third. Front angles of the pronotum project 

 forward rather strongly. First joint of front tarsus as long as 

 the second and third united.

Extremely variable in regard to size, and varies in colour from 

 reddish brown to dark brown, but with the elytra always of a 

 much lighter tint either reddish brown or tan-coloured. 



c?. Head very finely granulate and opaque, impressed with a 

 median groove that extends from the clypeus upwards between the 

 antennal tubers and the eyes, and thence is continued along the 

 vertex as a very fine linear groove or carina. Prothorax with its 

 sides slightly converging in front up to the base of the anterior 

 projections, furnished each with a series of short spines ; notum 

 very closely punctulate and opaque, but marked with certain well- 

 defined shining areas which are slightly raised and sparsely 

 punctate ; two of these near the middle are triangular in form 

 and conjoined at their inner angles, a third, narrow and transverse, 

 placed just in front of the base and two much smaller areas near 

 each side, the inner one irregular in form, the outer forming a 

 narrow oblique ridge ; a median polished line runs from the 

 basal band up to the junction of the two triangular areas and 

 for a short distance beyond. Scutellum closely punctulate and 

 opaque. Elytra about twice as long as their conjoint width ; these 

 present a finely granular and dull appearance except around the 

 base and for a short distance backwards along the suture. Body 

 very finely and closely punctulate beneath, except on a median 

 triangular area of the metasternum, on a transverse strip at 

 the hind border of each of the first four abdominal segments and 

 on the middle of the fifth segment, these parts being glossy. 

 Femora and tibiae spinulose along their dorsal and ventral faces, 

 the front femora asperate or rugulose on their front and hind 

 faces. Last ventral segment with rounded hind border fringed 

 with tawny hairs. 



$ . Antennae not reaching beyond the middle of the elytra. 

 Prothorax with its sides somewhat more strongly convergent in 

 front and more strongly spined; notum more irregularly and 

 much less closely punctulate, the punctures coarser towards the 

 sides and the slightly raised shining spaces, corresponding with 

 those of the male, ill-defined. Body beneath less closely and 

 evenly punctulate, the glossy area of the metasternum less well- 

 defined ; abdomen more or less glossy except near the sides ; last 

 ventral segment with a sinuate notch in the middle of hind 

 margin. Legs shorter and more slender ; front femora spinulose 

 as in the male, but not asperate. 

 Length 40-96 ; breadth 12-30 mm.
