COLEOPTERA. 135 



114. S. curttis n. sp. — Form rather robust. Pubescence somewhat 

 sparse, very fine, moderately long, cinereous, semi-recumbent on the abdo- 

 men. Head small, twice as wide as long; interocular surface slightly con- 

 vex ; coarsely, closely, and variolately punctate ; nearly three times as wide as 

 the eye; longitudinal elevation distinct; ocular lines meeting at two lengths 

 in advance ; antennae much longer than the width of head, rather slender, 

 dark, piceous-black, very slightly paler toward tip, club large ; third joint 

 one-third as long again as the fourth, fourth and fifth equal ; joints of club 

 gradually increasing in size, eleventh nearly as long as the ninth and tenth 

 together, acuminate at tip ; maxillary palpi dark blackish-fuscous, first joint 

 very slightly paler. Prothorax robust, widest slightly before the middle, 

 where it is seven-eighths as wide as the head, and but very slightly narrower 

 than long; sides thence moderately convergent posteriorly and very feebly 

 sinuate ; anterior and posterior margins about equal in length, equally 

 arcuate; surface evenly convex, very closely and rather coarsely punctate: 

 punctures variolate, irregular in outline, three to four times as wide as the 

 interspaces. Elytra at base notably wider than the head ; sides slightly 

 divergent posteriorly and evenly arcuate ; suture nearly one-third as long 

 again as the pronotum ; together broadly and feebly emarginate behind; 

 surface strongly and rather evenly convex, rather coarsely and evenly punc- 

 tate ; punctures rounded and sub- variolate, very slightly broader than the 

 interspaces, which are polished. Abdominal segments decreasing evenly 

 and rapidly in width; border narrow ; surface very convex, shining, rather 

 coarsely punctulate ; transverse carinae 4-cuspid, cusps very fine and short. 

 Under surface of the abdomen shining, finely punctulate ; pubescence increas- 

 ing rapidly in length and thickness toward the tip, where it is close, long, 

 recumbent, and fusco-cinereous. Legs slender, piceous-black ; first joint of 

 the posterior tarsi one-fourth as long again as the second, second equal to the 

 third. 



Mule. — Unknown. 



Female. — Posterior edge of the sixth ventral segment very broadly and 

 feebly arcuate throughout its width. 

 Length 2.0 mm. 



"White Fish Point, Northern Michigan, 1. 



A species very readily recognized by the short first joint of the 

 posterior tarsi. 



115. S. alacer n. sp. — Form slender. Pubescence rather short and 

 sparse, sub-recumbent, fine, pale piceo-cinereous. Head robust, moderate, 

 much less than twice as wide as long; interocular surface nearly twice as 

 wide as the eye, deeply excavated; longitudinal elevation in the form of a 

 very narrow, acute ridge, rising abruptly from the bottom; supra-antennal 

 tuberculations elongate, separated from the eye by shallow sulcations ; 

 punctures longitudinally coalescent, very unevenly distributed ; interspaces 

 polished and Hat ; ocular lines meeting at slightly more than one length in 

 advance; antennae much longer than the width of head, slender, piceous- 

 brown throughout, club slender; third joint slightly more than one-third 

 longer than the fourth, fourth and fifth sub-equal, sixth much longer and
