S melanarius, Steph. (cmerascens, Er., gracilenfus, Fairm., nigri- 



paljns, Thorns.). Black, rather dull, somewhat parallel-sided, witli the 

 hmd body rather convex and very slightly narrowed behind ; head evi-

 between them being broad and not raised in a keel ; antennjB rather 

 short, black, palpi Idack with first joint pitchy testaceous ; thorax and 

 elytra strongly and thickly punctured, the punctuation of the latter 

 being somewhat less close ; thorax longer than broad M-ith no trace of 

 dorsal channel ; elytra rather longer than thorax ; hind body shinin" 

 finely and rather diffusely punctured; legs bl.ck. L. 3 mm. 



Male with the seventh ventral segment of hind body feebly emarginate 

 at apex, and the hind body a little more narrowed behind than in 

 female. 



This species closely resembles S. morio, but differs in several im- 

 portant particulars ; from S. canaliculatus it may be at once .separated 

 by the absence of a dorsal channel on thorax- and from bupthalmus it 

 may be distinguished by its narrower tliorax, less strongly and rugosely 

 punctured elytra, and by the finer and more remote punctuation of the 

 hmd body ; it is, moreover, more slender and parallel-sided.

S. incanus, Er. This species is allied to the preceding, and also to 

 S. morio and ,S'. atmtulus; it is, however, narrower than any of them and 

 the colour is more leaden-grey, the insect being more distinctly clothed 

 with whitish pubescence; the f oreh( ad has tM'o broad deep furrows, the 

 space between them being strongly convex and as high as the outer sides 

 of the furrows ; the thorax and elytra are thickly and rather finely punc- 

 tured ; the elytra are plainly longer than the thorax, and are furnished 

 with one or two obscure depressions at base; the hind body is .spariu-lv
