obtuse elevations. Scutellum depressed and smooth in tlie middle, finely 

 punctate and pubescent at the sides. Elytra very slightly narrowed pos- 

 teriorly, nearly five times the length of thorax, evidently broader than 

 it is at the base, apices, conjointly, rounded ; their punctures are reddish, 

 evenly distributed but not seriate, they are not very coarse or close and 

 are much finer at the apices ; each elytron is indistinctly bicostate, the 

 suture is sharply marked nearly to the extremity. 



Antennae finely pubescent, their basal half with longer pale hairs ; 

 1st joint punctate, 3rd and 4th of about equal length, the 10th reaches the 

 extremity of the elytra. 



Underside fuscous, with slender grey pubescence. Prosternum finely 

 transversely rugose and punctate ; 5th ventral segment ciliate and, as well 

 as the short 6th, truncate at the apex. Palpi short and quite pallid. 



The thoracic sculpture, sharjjly defined elytral suture, and dark head 

 and thorax are good distinguishing characters.

Variegate, slightly nitid ; the sides of thorax, the shoulders, a broad 

 space extending from the side of each elytron to the suture and along it to 

 the apex more or less dark fuscous ; the sides of the posterior declivity, a 

 broad oblique space across each elytron before the middle, and an irregular 

 area between the middle and each side of the thorax obscure f usco-testaceous, 

 and clothed with depressed short greyish hairs, the darker areas, including 

 the middle of thorax, with infuscate pubescence ; these dark and pale 

 spaces are not always sharply defined and are more or less spotted. 



Thorax as long as broad, with nearly straight sides for two-thirds of the 

 length, narrowed near the base, with a transverse impression near the front ; 

 disc a little uneven, with a pair of slight elevations near the middle, and a 

 small almost white crest at each side towards the base ; there are only a 

 few coarse punctures above, but they become more numerous at the sides. 

 Scutellum triangular, infuscate. Elytra oviform, of the same width at the 

 base as the thorax, quite twice its length, the greatest breadth near the 

 middle ; on each there is a small, yet distinct, dark crest rather farther 

 from the base than it is from the suture, and a smaller pair on the hind margin 

 of the pale area ; the punctation is moderately coarse but not close on the 

 basal half, finer and subseriate towards the extremity, and soriiewhat oblique 

 near the sides. 



Femora clavate, shining, pale brown, witli some very fine greyish 

 pubescence. Tibiae testaceous, with 2 fuscous spots, the base reddish, 

 their pubescence most distinct near the extremity. 



Antennae testaceous, but with nearly the whole of the 3rd joint and the 

 apex of joints 4-11 fuscous, the 2nd rufescent, the 4th is almost as long as 

 the 3rd. 



The nearest species is S. picticGrnis. Ihe shape and sculpture of the 

 thorax, broad scutellum, and general coloration are, however, different.
