 lineis duabus longitudinalibus in interstitiis 3 et 7 postice ssepissime conjimctis ; prosterno

Colour shining black, with bands and stripes of white scaling ; prothorax with an 

 oblique lateral stripe from below the posterior angle almost to the front margin ; 

 elytra with a common backwardly curved narrow band near the base extending to 

 the sixth stria on each side, a reversely curved and slightly broader band behind the 

 middle, narrowly interrupted on the suture and reaching the margin a little in front 

 of the middle, and behind this two longitudinal stripes on the 3rd and 7th intervals 

 respectively, which generally unite at the apex ; the centre of the prosternum, the 

 epimera of the mesosternum, a large lateral triangular patch on the metasternum, and 

 the sides and apical margin of the 2nd, 3rd, and 4th ventral segments with dense 

 whitish scaling. 



Head bare, closely punctate, and with a deep frontal fovea. Rostrum extremely 

 long and slender in the $ , only slightly curved, a little widened at the insertion 

 of the antennae and again at the apex, with fine separate punctures at the base ; in 

 the c? , a little shorter and stouter, more coarsely and confluently punctate, and with 

 a short central stria between the antennae. Antennce with joint 1 of the funicle much 

 longer and stouter than 2, and 3 evidently longer than 4. Frothoracc a little broader 

 than long, broadest at the base and gradually narrowed to beyond the middle, then 

 very strongly constricted and subtubulate at the apex, the ocular lobes moderately 

 developed; the upper surface with close punctures of varying sizes and subcon fluent 

 towards the base, no central furrow or carina. Scutelluvi obovate, convex, and not 

 quite enclosed by the base of the elytra. Elytra with the shoulders only slightly 

 projecting and obliquely rounded, the sides subparallel to beyond the middle, 

 distinctly impressed transversely at the base, with shallow punctate stria?, the intervals
