cent. Eyes obliquely oval, normal in size. Antennae piceous, attaining the 

 middle of the thorax. Thorax broader than the head, as broad as long, 

 slightly narrowed in front, sides feebly, base more broadly arcuate, surface 

 densely and rather coarsely punctured, a smooth median line posteriorly, very 

 inconspicuously pubescent. Scutellum velvety. Elytra not wider than the 

 thorax, as wide conjointly as long, surface subopaque, densely punctate-scabrous 

 clothed with brownish pubescence. Abdomen above sparsely punctate, moder- 

 ately shining, slightly iridescent, sparsely clothed with brownish pubescence, 

 with sparse golden pubescence forming an undulating band along the base 

 of each segment, broader at the sides, segments 2 — 6 with a double series of 

 elongate velvety spots; beneath piceous, shining, iridescent, sparsely punctate 

 with brownish pubescence, each segment more finely and densely punctate 

 along the basal margin and with sparse golden pubescence. Body beneath 

 rather sparsely punctate. Legs variable in color, often entirely yellow, usually 

 the femora are piceous, the upper and lower edges yellow, the tibise and tarsi 

 yellow. Length .60 — .64 inch; 15 — 16 mm. 



This is the species heretofore labelled in collections femoratus^ but 

 M. Fauvel informs me that the latter name should belong to the 

 species to which it is applied in the present paper. 



Occurs in the New England States, Canada and New York and 

 Michigan. 



S. exulans Erichs., Staph, p. 374. — Form moderately elongate, piceous, 

 head, thorax and elytra distinctly brassy. Head comparatively small, sub- 

 triangular, coarsely and moderately densely punctured with a smooth vertical 

 space of variable size. Eyes obliquely oval, subtruncate in front. Antennae 

 piceous, attaining the middle of the thorax. Thorax a little wider than the 

 head, slightly narrowed in front, as wide as long, sides feebly base more broadly 

 arcuate, surface moderately shining, coarsely and moderately densely punc- 

 tured, a smooth median line wider posteriorly, on each side small smooth 

 spaces of variable size. Scutellum velvety. Elytra a little wider than the 

 thorax, conjointly as wide as long, subopaque, surface densely punctured and 

 scabrous and sparsely clothed with pale brownish pubescence. Abdomen above 

 feebly shining sparsely punctulate, sparsely clothed with brownish pubescence 

 with a little golden pubescence at the sides and the apex of each segment, 

 2 — 5 with a double series of velvety spots sometimes visible on the sixth also; 

 abdomen beneath piceous, iridescent, sparsely punctate, sparsely clothed with 

 brownish pubescence intermixed with yellowish near the base and sides of 

 each segment. Body beneath rather finely but not densely punctate. Legs 

 piceous, femora fi«ely punctulate. Length .44 — .56 inch ; 11 — 14 mm. 



This species could hardly be confounded with any other from its 

 color and sculpture, it bears a certain amount of resemblance however 

 to comes in which the legs are always pale. 



Occurs from Canada to Georgia, but rare.

 Lee, New Species, 1863, p. 37. — Form moderately elongate, piceous black, 

 head and thorax slightly aeneous. Head subtriangular, comparatively small, 

 coarsely very sparsely punctured and with a large smooth vertical space, 

 slightly pubescent behind the eyes where the punctuation is dense. Eyes 

 obliquely oval. Antennae piceous attaining the middle of the thorax. Thorax
