130 NORTH AMERICAN 



times as wide as the eve; deeply, coarsely, and rather closely punctate ; 

 longitudinal elevation very prominent; antennae slender, equal in length 

 to the width of head, uniformly fusco-testaceous, club well developed; third 

 joint but very slightly longer than the fourth; joints of club gradually in- 

 creasing in length and thickness, last joint acuminate at tip ; entire antenna 

 bristling with long setae ; eyes coarsely setose ; palpi uniformly flavo-testa- 

 cetms. Prothorax widest just before the middle ; sides thence moderately 

 convergent posteriorly and feebly sinuate ; length slightly greater than the 

 breadth ; anterior and posterior margins equal and arcuate; surface coarsely 

 and irregularly punctate and tuberculate : interspaces polished. Elytra at 

 base very slightly narrower than the head ; sides very moderately divergent 

 posteriorly and arcuate ; together broadly and very feebly emarginate behind ; 

 suture one-fifth as long again as the pronotum ; surface coarsely and irregu- 

 larly punctate ; punctures impressed; interspaces highly polished ; on each 

 elytron there are three tuberculiform elevations. Abdominal segments 

 decreasing very moderately in width, first nearly as wide as the adjoining 

 elytra; border prominent; surface shining and rather coarsely punctate, 

 transverse carinae not cusped. Legs short, fusco-testaceous, hirsute; tarsi 

 very pale in color ; first joint of the posterior equal in length to twice the 

 second, second equal to the third. Under surface of the abdomen blackish- 

 piceous, coarsely and distantly punctate, bristling with long erect setae. 



Male. — Posterior edge of the sixth ventral segment broadly and trans- 

 versely truncate ; seventh deeply emarginate at apex. 



Fondle. — Sixth segment broadly and triangularly produced posteriorly, 

 with the apex rounded. 



Length 2.3—2.6 mm. 



Florida; Sand Point, 5; Enterprise, 1. 



This species may be very readily recognized by the irregularities 

 of the surface, there being ten very apparent tuberculations — four on 

 the pronotum and six on the elytra — as well as by its very bristling 

 and hirsute appearance. 



110. S. iiulist iiic-tiis n. sp. (Schwarz MS.). — Form moderately slender. 

 Pubescence rather short and close, cinereous in color throughout. Head 

 moderate, twice as wide as long ; interocular surface about two and one-half 

 times as wide as the eye, very feebly excavated and closely punctate ; punc- 

 tures variolate ; longitudinal elevation scarcely evident; ocular lines meeting 

 at one and one-half lengths in advance ; antennae nearly black, moderately 

 robust and rather finely setose, club moderate, third joint one-third as long 

 again as the fourth, joints of club gradually increasing in thickness and 

 length ; maxillary palpi reddish-brown, first joint a little paler. Prothorax 

 widest at one-third its length from the anterior margin, where it is four-fifths 

 as wide as the head ; sides thence rather rapidly convergent and almost 

 straight ; length one-fifth greater than the breadth ; anterior margin slightly 

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

 versely impressed near the anterior and posterior margins, very closely 

 punctate; punctures variolately impressed; interspaces narrower than the
