beliind tlie neck than tliat of A. fofp, and anterior angles 

 more depressed, the lateral margin is in consequence less 

 visible above ; the scutellum obscurely ]junctulate ; the elytra 

 striate-yjunctate, interstices flat, with leather-like sculpture, 

 impunctate ; the antennae and legs black. Male : clypeus 

 with an outline nearly straight, ocular carina anteriorly spread 

 out over the base of the antenna, with two short, obtuse, and 

 somewhat tubercular horns over the eyes. The female has 

 a small carina over the anterior portion of the edge of the eye. 



This species is similar to A. fcigi^ but the convexity and 

 depression of the anterior angles of the thorax, the sculpture 

 of the elytra, and the colour of the antennte and legs are, 

 amongst others, good distinguishing characters.

Elongate, black, rather shining ; the head somewhat densely 

 punctured on the neck and anterior portion, more sparingly 

 between the eyes ; the thorax marginate at sides and base, 

 margin interrupted behind the neck, punctured rather more 

 finely than the head, with a feeble median longitudinal 

 impression (absent in some exani])les) ; the elytra striate- 

 punctate, interstices with a leather-like sculpture; the fore 

 tibiaa longer and more bent in the male than in the female ; 

 the metasternum free of pilosity in both sexes ; the antennw, 

 third joint somewhat longer than the fourth. 



This species differs from S. valfjipes, Mars., in the male 

 having a smooth metasternum and simple intermediate and 

 hind tibia? ; in both sexes the chief ditierences are the want 

 of a thoracic canaliculation and the third joint of the antenna 

 is shorter jmd stouter. A species from Mantchuria {S. vi/lo- 

 si'pes) noticed by Marscul has the metasternum furnished, like 

 S. volgipeSy with yellow hair.
