116 NORTH AMERICAN 



The above description seems to agree in all essential points with 

 that given by Erichson for the European canaliculatus, but having 

 no specimens of the latter for comparison, I cannot state that the 

 identification is conclusive. 



92. S. Carolina? n. sp. — Form rather slender. Pubescence moderately- 

 close, extremely long, coarse, erect, pale fuscous in color. Head rather 

 small, not twice as wide as long ; interoenlar surface flat, coarsely and closely 

 punctate, two and one-half times as wide as the eye ; longitudinal elevation 

 very slight but rather abruptly limited at the sides ; antennae slender, very 

 slightly longer than the width of head, fuscous, coarsely setose, club dis- 

 tinct ; third joint one-third as long again as the fourth, joints six and seven 

 equal in length, ten and eleven equal in thickness, and notably longer than 

 the ninth, eleventh much longer than the tenth, acuminate at tip ; maxillary 

 palpi liavo-testaceous, slightly darker toward the tip. Prothorax widest 

 before the middle, where it is four-fifths as wide as the head, and one-sixth 

 narrower than long, sides thence gently convergent posteriorly, and nearly 

 straight : surface having an irregular longitudinal elevation at each side. 

 and a slight transverse depression just behind the anterior margin, coarsely 

 and somewhat irregularly punctate; punctures deeply impressed; inter- 

 spaces generally equal to about one-half their width, highly polished. 

 Elytra at base just perceptibly widen than the head ; sides almost parallel, 

 rather strongly arcuate toward the apices ; together broadly and very feebly 

 ejnarginate behind ; suture about one-sixth as long again as the pronotum ; 



' surface of each slightly swollen at the base near the middle ; coarsely, some- 

 what regularly punctate ; punctures deeply impressed ; interspaces one-half 

 as wide, highly polished. Abdominal segments decreasing extremely gradu- 

 ally in width, first nearly as wide as the elytra, border moderately prominent ; 

 surface convex, highly polished, coarsely punctulate ; transverse carinae 

 obscurely cusped and finely serrulate, cusps very short, rounded at tip. 

 Legs rather short and stout, rufo-testaceous, tarsi paler ; first joint of 

 posterior two-thirds as long again as the second, next three joints gradually 

 decreasing in length. Under surface of the abdomen more finely punctulate, 

 black, terminal segments paler. 



Male. — Posterior edge of the sixth ventral segment broadly emarginate, 

 emargination evenly rounded, eight times as wide as deep ; seventh deeply 

 emarginate at apex, with the sides produced denticulately. 



Female. — Sixth segment broadly rounded behind. 



Length 2.S-3.0 mm. 



Southern States, 3; Selma, Alabama, 1; Tallahassee, Florida, 1. 

 The coarsely herissate vestiture of this species renders it very dis- 

 tinct. 



93. S. ageilS n. sp. — Form rather robust. Pubescence somewhat short, 

 cinereous, evenly distributed, sub-recumbent, fine, and rather close. Head 

 moderate, twice as wide as long ; interocular surface more than twice as wide 

 as the eye, feebly convex ; sulcations almost obsolete ; punctures very deep,
