equal in length, the latter much the thicker, eighth slightly longer than 

 wide, slightly cordate, and just perceptibly narrower than the seventh, joints 

 of club increasing in length, ninth small, tenth much the broadest : maxil- 

 lary palpi dark piceous-brown, first joint dark piceo-testaceous. Prothorax 

 arcuately, evenly, and very gradually increasing in width to the middle, 

 where it is seven-eighths as wide as the head and distinctly narrower than 

 long; sides thence feebly convergent posteriorly and feebly sinuate ; anterior 

 margin slightly longer than the posterior, equally arcuate ; surface trans- 

 versely and feebly impressed just behind the apex, finely, extremely closely, 

 confusedly, and very deeply sculptured, interspaces acute and lustreless; 

 canaliculation narrow, slight, beginning at the middle, nearly one-third as 

 long as the pronotum. Elytra at base slightly wider than the; head ; sides 

 feebly divergent posteriorly, longer than the width at base, and nearly 

 straight, except toward the apices where they are feebly arcuate ; together 

 very narrowly and strongly emarginate behind ; suture nearly one-third as 

 long again as the pronotum; surface rather finely, very deeply, extremely 

 closely, and irregularly channeled, interspaces acute. Abdominal segments 

 decreasing uniformly and rather rapidly in width, first slightly narrower 

 than the contiguous elytra ; surface very coarsely, feebly, closely, and evenly 

 punctulate ; transverse carinae not cusped, sometimes sex- or poly-dentate, 

 teeth small and acute. Legs long and slender, piceous- black, tarsi very 

 long and slender, paler ; first joint of posterior tarsi three-fourths as long 

 again as the second, longer than the fifth, joints two to four uniformly and 

 rapidly decreasing in length, tilth as long as the third and fourth together. 



Mali-. — Fifth ventral segment very feebly emarginate in tin.' middle, curve 

 just perceptible and very short ; sixth segment truncate at tip. 



Female. — Sixth segment narrowly, strongly, and triangularly produced at 

 apex. 



Length 3.2-3.6 mm.

55. S. maritiimis Mots. — Form moderately robust. Pubescence ex- 

 cessively sparse, rather long, recumbent, fine, and cinereous. Head rather 

 large, twice as wide as long ; interocular surface nearly fiat, sub-equally 

 trilobed by the rather conspicuous sulcations ; sparsely, finely, and very 

 irregularly punctate ; longitudinal elevation moderate, almost impunctate, 

 evenly convex ; ocular lines meeting at one length ; antennae as long as the 

 width of head, rather slender, black, last four joints much paler, club distinct ; 

 third joint one-half as long again as the fourth, fourth slightly longer than 

 fifth, sixth much shorter, joints of club increasing in length; maxillary 

 palpi pale flavo-testaceons throughout, third joint scarcely longer than the 

 second. Prothorax robust, sides strongly divergent and nearly straight to a 

 point one-third the entire length from the anterior margin, where the width 

 is nearly equal to the length, the sides thence converge rather rapidly, and 

 are almost straight ; anterior margin much shorter than the posterior, nearly 

 equally arcuate ; surface coarsely and moderately closely punctate, punctures 

 feebly impressed, in t ers j >ac< 's very convex, polished ; canaliculation roundly
