of basal angles ; scutellum only moderately long, very sharp ; elytra

 intermediate coxae separated by a narrow, round mesosternal keel ; 

 prosternum with a minute porrect process with a few setae ; anterior

Black, not glossy, generally covered with an earthy indumentum, 

 every puncture on the upper and under sides emits a minute, 

 luteous hair ; head and clypeus with round, contiguous punctures ; 

 the prothorax, which would be orbicular but for a tendency to be 

 slightly bluntly angular in the median part, is covered with similar 

 but slightly larger punctures, in the centre of the disk are two small, 

 spot-like smooth areas, and a shallow, very short, median longi- 

 tudinal line above the base which is arcuately rounded ; scutellum 

 punctate ; elytra broader than the prothorax, sinuate laterally and 

 having on each side two broad longitudinal impressions, so shallow, 

 however, that the intervening space is not raised enough to be con- 

 sidered as a costule, and a supra-lateral one which is deeper in the 

 posterior part, the dorsal part is covered with very elongated, cicatri- 

 cose punctures the sharp walls of which form an irregular, interrupted 

 strigillation ; pygidium, under side, and legs roughly punctate. 



Feeds on low plants that have been attacked by Coccidce or Aphides 

 (G. A. K. Marshall). 



Length 9-10 mm. ; width 4-4f mm.

Mentum proper short, deeply excavated on each side, ligular part 

 broadly arcuately dilated, separated from the mentum by a trans- 

 verse smooth keel overhanging the two basal cavities of the mentum 

 proper, and triangular and setulose in the centre, strongly sloping 

 thence to the anterior part the margin of which is plainly renexed in 

 the centre, the palpal cavities are very much reduced, angular at the
