longer than broad, plainly narrowing laterally from the median part 

 to the apex, hut nearly straight from the middle to the base the 

 angle of which is very sharp, closely rugose punctate and covered 

 with a long, sub-erect, very dense flavescent pubescence ; scutellum 

 deeply and somewhat roughly punctate ; elytra one-fifth longer than 

 broad, hardly narrower at apex than at base, somewhat convex in 

 the anterior dorsal part, but not so in the posterior, and having 

 a distinctly raised, rounded, supra-marginal ridge on which the 

 fuscous band runs, and reaching from the humeral callus to the 

 apex ; on the surface are sparsely scattered, very shallow, and 

 extremely fine punctures ; pygidium finely shagreened and clothed 

 with long hairs ; abdomen punctulate ; pectus shagreened, the whole 

 under side and legs very hairy, the hairs sub-flavescent ; intermediate 

 tibia? slightly arcuate, anterior tibiae with two distinct apical outer 

 teeth and a sinuation above the second tooth. 



Female : Clypeus more arcuate laterally from the base to the 

 apex the anterior part of which is thus narrower than in the male, 

 but is equally deeply emarginate, the sculpture is nearly the same, 

 but the head is not thickly pubescent in my examples, nor is the 

 prothorax which bears only a few scattered hairs, and is much more 

 broadly and more deeply punctate instead of being shagreened ; the 

 elytra are more convex, plainly ampliate behind, and coarsely 

 punctate, especially in the median part, the pubescence of the 

 pygidium and also of the under side is shorter ; the anterior tibiae 

 are plainly tri-dentate outwardly, and the lower spur of the hind 

 tarsi, more compressed and blunter at tip than the upper. 



Length 13-17| mm. ; width 8-9 mm.

Metallic green, with the elytra greenish flavescent or flavescent 

 and very narrowly marginated with black, suture with a bright 

 green band ; legs bluish-black. This species so closely resembles 

 S. rittatus in general appearance, as well as in colouration, that it 

 might be easily taken for the same, but it is smaller; the elytra 

 have no traces of the supra-lateral infusoate band; the antennae 

 including the club are rufescent instead of being black or deeply 

 infuscate ; the head and prothorax of the female are as densely 

 hairy as those of the male, but in the latter the punctures are 

 slightly more asperous, the body is narrower and less ampliated 

 behind in the female; the elytra of the male are more distinctly
