so broad as the elytra, densely and coarsely punctured, a 

 little excavate, distinctly bisulcate, and with a narrow 

 central carina. Hind body slender; the basal segment 

 marginate, and the anterior portion of the next following 

 segment finely margined, the others immarginate ; the 

 segments rather closely punctured, the punctures on the 

 basal segment quite distinct, but becoming less deep on 

 the following segments,, so as to be obsolete on the penul- 

 timate segments; the segments bear also a fine, depressed, 

 scanty, ashy pubescence. The legs are long and slender, 

 the hind tarsi elongate and slendei", with the 4th joint 

 simple ; the coxa? are pitchy black, the femora are yellowish, 

 but somewhat infuscate towards the extremity, and the 

 tarsi become more obscure in colour towards the apex. 



In the male the 6th segment beneath is broadly but 

 faintly impressed along the middle ; the impressed part is 

 pubescent and densely punctured; the pubescence towards 

 the apex of the segment is dense at each side of the 

 impression, the hind margin scarcely emarginate ; the 

 following segment bears a narrow elongate notch. 



Ega ; two males. 



Obs. — This species is closely allied to S. inspector, but 

 is undoubtedly distinct ; the character of the sculpture is 

 very similar, but is less dense on the thoi'ax and elytra of 

 6". obductus ; and other less striking ditferences are con- 

 veyed by the two descriptions ; the tarsi of ^S". obductus 

 have the 4th joint slender and simple.
