an arcuate impression below the vertex, rather closely punctured, 

 and with the carina replaced by a non-elevated smooth line ; 

 vertex opaque, impunctate ; eyes small, ' emarginate ; mandibles 

 very prominent ; antennae brown-testaceous, normal. Prothorax 

 fully one-half longer than wide, constricted behind the middle, 

 thence ampliated, and widest behind the apex, the anterior angles 

 broadly rounded with the outer parts of the apical mai'gin, which is 

 almost bilobed, being separately rounded on either side with a very 

 shallow median indentation, hiud-angles broadly rounded, the base 

 truncate in the middle ; surface moderately convex from side to 

 side, depressed longitudinally and (in side view) appearing flat 

 from just before the base to the anterior fourth, where it becomes 

 declivous and convex, apical margin tubercnlate, the anterior half 

 asperate with rather coarse granules, and pilose with fine erect 

 hairs, posterior half moderately shining, more thinly hairy, weakly 

 punctured, the punctures closer in front than at the base, which is 

 somewhat calloseh^ thickened. Scutellnm minute. Elytra as wide 

 as the prothorax, but scarcely so long, subparallel sided, not 

 narrowed behind, and broadly rounded at the apex ; cylindrico- 

 convex to the middle, thence convexly declivous, coriaceous, finely 

 and confusedly punctured and moderately densely clothed with 

 fine hairs ; declivity rugulose, obsoletely striate, not margined 

 below. Coxae and underside, except the abdomen, darker, thinly 

 hairy ; the latter short. Legs ferruginous, the knees and tibiai 

 darker ; femora very stout, inflated ; tibia; rounded externally, the 

 anterior pair narrow, weakly armed, the remaining pairs dilated in 

 the middle, and more strongly serrate above ; tarsi very long, the 

 first three joints somewhat stout and compressed. 



Hab. Sumatra, from tobacco (Grouvelle). 



This form is one of the most singular among the many 

 remarkable male forms of the genus. The great length 

 of the prothorax, and its peculiar shape, are quite 

 characteristic ; its apical indentation is only such as 

 results from the conjunction of the two curves formed by 

 the independently rounded sides of the anterior margin, 

 and there is no dorsal sulcus leading to it. In spite of 

 its great length, the prothorax is not, as in many males, 

 produced into a peak in front of the head.
