 with the usual bristles, except that at lower angles there are two stouter 

 ones, the lower smaller. Labial palpi nearly equaling the anterior 

 coxpe. 



Pronotum with a transverse row of ten or twelve bristles on the pos- 

 terior third, the hind margin with a ctenidium of about twenty stout 

 spines. The posterior row of bristles on meso and metanotum of ten 

 rather long ones, the anterior row of more numerous and smaller ones.

 abdomen each with twelve or fourteen larger bristles in the posterior 

 row, fewer smaller ones in the anterior row. Antepygidia bristles 

 three on each side, the middle one of each group largest, and reaching 

 over pygidium, the inner smallest. Middle abdominal sternites each 

 with a row of a])out eight stout bristles; posteriorly the sternites have 

 a second row of few bristles. Beneath the pygidium laterally occur 

 three large bristles. Hind margin of eighth segment laterally with 

 about six strong bristles around the lower angle. 



The style is about two times as long as wide at base, gradually nar-

 on lower margin just back of tip. Substylar flap obtuse at tip, near
