AMERICAN COLEOPTERA. 193 



late, with brownish pubescence. Body beneath moderately densely punctulate. 

 Legs piceous, femora densely punctate, tarsi usually paler. Length .60 inch; 

 15 mm. 



The abdomen above in the majority of specimens is unicolorous, 

 sometimes however the tip is slightly paler; beneath the fifth and 

 sixth ventrals are often reddish brown. The species is very closely 

 allied to mi/sficus, but the latter has no smooth median thoracic line 

 while the present has. In well preserved specimens the pubescence 

 on the elytra is slightly variegated, somewhat holosericeous. 



Occurs from Sitkha to California and Arizona. 



S. femoratus Fab., Syst. El. ii, p. 394; Erichs. Staph. 393; varipes Saclise, 

 Stettin Zeitschr. 1852, p. 126.— Moderately elongate, piceous, head, thorax and 

 elytra slightly aeneous, last ventral segment and upper side of femora pale 

 yellowish. Head rather small, subtriangular, coarsely densely punctured, 

 sparsely pubescent, vertex flat. Eyes larger than usual, occupying two-thirds 

 the length of the head, oval, truncate in front. Antennae nearly reaching the 

 middle of the thorax, piceous, basal joint margined with testaceous. Thorax 

 a little wider than the head, a very little longer than wide, sides very feebly 

 arcuate, base broadly so, surface punctured similarly to the head, with a 

 smooth line posteriorly, sparsely clothed with brownish pubescence. Scu- 

 tellum velvety. Elytra a very little wider than the thorax, slightly longer 

 than wide, densely finely punctate-scabrous, subopaque, sparsely clothed with 

 brownish pubescence. Abdomen finely sparsely punctate, and sparsely clothed 

 with brownish hair, segments 2 — 6 with a feebly marked double series of 

 velvety spots, last segment yellowish testaceous; beneath iridescent, moder- 

 ately densely punctate, sparsely clothed with pale brownish pubescence. 

 Body moderately densely punctate. Femora punctate, pale yellowish above, 

 piceous beneath, tibise and tarsi piceous. Length .60 inch; 15 mm. 



This species bears a certain resemblance to exu/ans but differs in 

 sculpture, color of abdomen and legs. It differs abundantly from all 

 our species in the size of the eyes as compared with the length of 

 the head. 



Occurs in the Southern States but appears to be rare, the only 

 perfect specimen before me was given me by Mr. E. P. Austin, who 

 received it from Georgia. 



S. tomenfosus Grav., Micr. p. 161; Erichs. Staph, p. 389.— Moderately 

 elongate, black, opaque. Head subtriangular, very densely punctured and 

 with short black pubescence. Eyes obliquely oval, subtruncate in front. 

 Antennae a little longer than the head, black. Thorax as wide as the head, 

 a little longer than wide, sides nearly straight or very feebly arcuate, base 

 broadly arcuate, surface very densely punctured with feeble trace of a smoother 

 line posteriorly, clothed with short black pubescence. Scutellum velvety. 

 Elytra a little wider than the thorax, as wide conjointly as long, very densely 

 punctured and with short black pubescence. Abdomen above finely and 

 moderately densely punctulate and with short black pubescence, segments 

 2_6 with a double row of velvety spots; beneath rather sparsely punctate, 

 the first segment a little more densely, segments 2 — 6 a little more closely
