AMERICAN COLEOPTERA. 189 



under the latter. The color above and beneath is entirely piceous, 

 and invariable as far as I have seen. 



Occurs from the New England States westward through Canada, 

 New York and Michigan. 



S. plenralis Lee., Proc. Acad. 1861, p. 343.— Form moderately elongate. 

 Head orbicular, piceous, surface moderately densely punctate, more sparsely 

 in front and less coarsely than the thorax. Eyes round, anteriorly subtruncate. 

 AntennsB a little longer than the head, rufo-ferruginous. Thorax piceous, a 

 little longer than wide and narrower than the head, sides posteriorly feebly 

 sinuate, base arcuate, apex truncate the angles distinct but obtuse, surface 

 densely punctured with a narrow smooth median line. Scutellum tomentose 

 with black pubescence. Elytra conjointly wider than long, broader than the 

 thorax, densely punctate, color varying from brownish to ferruginous and 

 sparsely clothed with short ferruginous pubescence. Abdomen piceous, finely 

 but not densely punctate, last four segments with coarse and deep punctures 

 irregularly scattered, surface sparsely clothed with brownish pubescence, serice- 

 ous along the anterior portions of the segments, beneath very sparsely punctate 

 and with inconspicuous pubescence. Metasternum coarsely punctured. Legs 

 usually pale rufous, coxae and femora sometimes piceous. Length .60 inch; 

 15 mm. 



In well preserved specimens the head and thorax are clothed with 

 very short brownish hair, which is apt to be entirely removed by the 

 usual methods of collecting. 



This species may be confounded with badtpes which differs in a 

 denser punctuation of head and thorax, a small golden spot of pubes- 

 cence at the middle of the anterior margin of each segment, and the 

 abdomen more punctured beneath with sericeous pubescence along the 

 anterior margin of each segment. 



Occurs in Utah, Oregon and Vancouver. 



S. sapliyi'iuus Lee, Proc. Acad. 1861, p. 342. — Form moderately elongate, 

 body beneath piceous, legs rufous, head, thorax and elytra blue, abdomen 

 piceous, segments 6—8 red. Head orbicular, densely punctured with very 

 feeble smooth line posteriorly. Eyes oblique, subtruncate in front. Antennae 

 rufous or rufo-piceous, attaining the middle of the thorax. Thorax a little 

 narrower than the head, longer than wide, slightly narrowed toward apex, 

 sides feebly arcuate, posteriorly sinuate, surface densely punctured with dis- 

 tinct smooth median line. Scutellum punctured, pubescent. Elytra as wide 

 or a little wider than the head, conjointly as wide as long, densely punctured, 

 punctures finer than those of the thorax, sparsely clothed with brownish 

 pubescence. Abdomen sparsely punctulate, clothed with brownish pubescence 

 and on the last three with reddish pubescence. Body beneath and abdomen 

 sparsely punctate, last three segments of latter red and with rufous pubescence. 

 Legs pale rufous. Length .40 — .60 inch ; 10 — 15 mm. 



A very pretty and distinct species, the larger specimens resem- 

 bling superficially rutilicauda which differs in the form of head
