(?. Rufescent brown, femora and tibiae rufous ; pubescence of upperside 

 olivaceous copper}- brown ; rostrum sparsely grey ; a line dorsally on each side 

 of head bordering eye, continued obliquely across proaotnm to base, slightly 

 widening behind, and a triangular mesial spot from base to near middle of 

 pronotum clayish grey ; scutellum the same colour ; on elytrum a line beginning 

 with a transverse spot situated before middle of the lateral margin, running along 

 the seventh interspace to near apical declivity, turning towards suture, which it 

 does not quite reach, and extending forward, circumventing a brown sutural dot 

 before middle, then being widened and continued to base, and turning along basal 

 margin to shoulder, here produced a little backwards ; the area encircled by this 

 clayish grey line sparsely shaded with grey ; a small transverse subapical spot 

 clayish grey, base of suture not brown ; pygidium with a grey mesial line and a 

 grey border ; underside with clayish grey lateral stripe from head to fourth 

 abdominal segment, this stripe gradually fading away towards middle, which is 

 very thinly pubescent grey like legs. 



Rostrum very densely rugate-punctate, without carinae, apical sinus rounded. 

 Frons with sulcate mesial carina and some cariniform wrinkles. Antenna long, 

 reaching base of prothorax, segment 3 nearly three times as long as 2, 8 triangular, 

 twice as long as apically broad, club elongate, ',) more than twice as long as broad, 

 10 half as long again as broad, 11 a little longer than 10, truncate. Prothorax 

 half as broad again as long, conical, not depressed above, very densely punctate- 

 reticulate. Elytra slightly depressed above, finely punctate-striate, gradually 

 narrowed from before middle to near apex. Antecoxal portion of presternum a 

 little shorter than the coxa is broad. Mesosternal process convex, apex curved 

 Ijackwards, rounded. Abdomen irregularly impressed mesially, impression especially 

 deep on segments 4 and .5, 4 with an ochraceous tuft on each side of impression, 

 5 subtruncate. Foretarsns sliglitly dilated, first segment one-third the length of

 pronotum rather narrower, the pygidium more extended brown, and the brown 

 lateral spots on metasternum and first abdominal segment larger. Pronotum 

 mesially less depressed before carina. Elytra rather narrower, without any stripes 

 of large punctures, the sutural stripe alone being present, but impunctate 

 Pygidium of ? a little more pointed. Mesosternal process as mjiyxrattis, vertical, 

 concave before being curved back, almost apjiearing bituberculato. Metasternum
