?. Black ; very s])arsely irrorated witli grey above, densely grey beneath ; 

 tibiae with grey ring in middle and at apex ; claw-segment rufons ; two minute 

 dots on head close to eye and a larger mesial spot at apex of ])ronotum greyish 

 white ; three dots behind carina, and scutellnm sparsely grey ; elytrum with the 

 sntnral interspace tesselated with black and clayish grey from before middle to 

 apical declivity, second and ' third interspaces ochraceons to tlie same extent, 

 third with a black tubercle in middle and t-ome dark dots, fourth and fifth 

 with a small greyish ochraceons spot before apical declivity ; the patch thus 

 formed stopping behind the subbasal callosity, which is strongly elevate, tuberculi- 

 form, clothed with black hairs on the top. Antenna rufous brown, segment 8 

 much shorter than 7, but a little broader at apex, club loose, H and 10 triangular, 

 truncate, oue-fourth longer than broad, 10 slightly rounded at the sides, as 

 long as broad, 11 pale at apex, ovate, nearly as long as 0, a little longer 

 than broad. Pronotum witli central tubercle situated in a rather deep depression, 

 sides of disc elevate ; carina subbasal, angle less than 90', lateral carina not 

 reaching middle. Elytra transversely depressed between subbasal callosity and 

 median tubercle, fifth interspace snbtuberculate before apical declivity and feebly 

 elevate also in middle, where it is black.

 close to eye, a mesial apical spot and three basal dots on pronotum, scutellnm

 reaching from scutellnm to apical declivity, narrowed in front, its oblique anterior 

 edge running across the inner side of the subbasal callosity, rounded-truncate 

 behind, expanded between the sixth stripes of punctures, suture densely tesselated 

 with black, third interspace with an elongate raised lilack sjwt before middle
