Sphenophorus hebetatus, Gyll. in Schonh. Gen. Cure. iv. p. 919 x ; Boh. op. cit. viii. 2, p. 243 \ 



Elongate-oval, densely olivaceo- or brownish-grey-pruinose (when fresh), black, the prothorax sometimes 

 ferruginous, except down the middle and along the sides, or with an oblique rufous stripe on each side 

 anteriorly ; the elytra ferruginous, with a common large transverse patch before the middle, a patch below 

 the shoulder, and rather more than the apical third black, the ferruginous portion sometimes reduced to a 

 large laterally-dilated C-shaped patch on the disc of each elytron or altogether wanting ; the legs and 

 under surface sometimes rufo-maculate. Rostrum arcuate, fully as long as the prothorax, rather 

 slender, compressed, closely punctured at the base, obsoletely punctate in its outer half, the abruptly- 

 widened basal portion striato-punctate and canaliculate ; that of the $ with the long apical portion 

 more slender, subcylindrical, and almost smooth. Prothorax flattened on the disc, sparsely, rather 

 coarsely punctate, feebly bisinuate at the base. Scutellum elongate-triangular, flat. Elytra finely 

 punctate-striate, the interstices somewhat convex, uniseriate-punctate. Pygidium cristate. Beneath 

 coarsely punctate ; metasternum and first two ventral segments broadly excavate down the middle in 

 the 6 , flattened in the $ . Anterior and intermediate coxae each with a small tuft of fulvous hairs. 

 Femora finely pubescent beneath. Tibiae with a dense fringe of very short hairs within. Third tarsal 

 joint comparatively small, about twice as wide as the apex of the second.

The markings of the elytra in this insect are almost hidden by the dense brownish-grey

. ■ ■ 







Elongate, subfusiform, rather narrow, flattened, alutaeeous, and opaque above ; ferruginous, the prothorax 

 with an incomplete median vitta, a small oblong streak near the outer margin towards the base, and a 

 stripe on the flanks, black ; the elytra each with an oblique subtriangular spot near the suture before 

 the middle and an interrupted submarginal stripe (formed by three oblong streaks, the subapical one 

 indistinct) black; the scutellum, knees, and under surface black, the sides of the meso- and metasternum 

 and of tjie abdomen rufo-maculate. Eostrum moderately stout, strongly arcuate, a little shorter than 

 the prothorax, the widened basal portion closely punctate, the apical portion somewhat compressed and 

 almost smooth. Prothorax a little longer than broad, obliquely narrowed anteriorly, the sides parallel 

 behind, the base subtruncate ; rather closely, irregularly punctate (the punctures here and there much 

 coarser and clustered into denser patches), the disc depressed in the middle near the base. Scutellum 

 elongate-triangular, slightly hollowed down the centre. Elytra oblong-subcordate, finely punctate-striate, 

 the interstices almost impunctate. Pygidium finely punctured, with two small tufts of fulvous hair at 

 the tip. Beneath shallowly punctate, the interspaces alutaeeous. 



Length 10-101, breadth 3^-3^ miilim. ( $ .)
