COLEOPTERA. Ill 



87. S. Illilleporus n. sp. (Fauvel MS.). — Form moderately robust, 

 males more slender. Pubescence very long, erect, moderately dense, dark 

 cinereous. Head very small, twice as wide as long ; interocular surface 

 very sligbtly convex, equally trilobed by the conspicuous sulcations ; interme- 

 diate surface evenly convex ; punctures large, round, impressed, and close; 

 interspaces very convex and highly polished ; ocular lines meeting at three 

 or four lengths in advance; antennae slender, much longer than the width 

 of head, coarsely setose, base black, remainder piceous, club distinct; joints 

 three to six sub-equal, sixth very slightly longer than the seventh, eighth 

 elongated slightly, joints of club increasing in length, last two very robust ; 

 maxillary palpi piceous, first joint paler. Prothorax widest slightly before 

 the middle, where it is from one-sixth to one-seventh narrower than long ; 

 sides thence just perceptibly convergent posteriorly and deeply sinuate; 

 anterior margin very slightly longer and more arcuate than the posterior ; 

 surface flat above, abruptly declivous at the sides ; deeply, closely, and 

 irregularly punctate ; interspaces very convex, highly polished : canalicula- 

 tion as in vinnulus. Elytra at base wider than the head ; sides very feebly 

 divergent posteriorly, rather strongly arcuate, and very slightly longer than 

 the basal width ; together broadly and just perceptibly emarginate behind ; 

 suture one sixth as long again as the pronotum ; surface convex, impressed 

 along the suture and near the outer apical angles, coarsely, rather closely, 

 and somewhat irregularly punctate ; punctures round, deeply impressed, 

 and varying in size ; interspaces convex and highly polished. Abdominal 

 segments decreasing uniformly in width, rapidly in the males, slowly in the 

 females ; first narrower than the contiguous elytra ; surface convex, coarsely 

 and closely punctulate at the sides, impunctate and highly polished along 

 the middle ; transverse carinae 4-cuspid, cusps approximate, long, acicular, 

 prominent ; under surface coarsely punctulate at base, becoming very finely 

 and closely so at tip ; clothed rather sparsely with long semi-erect setae. 

 Legs short, moderately slender, black ; tarsi slightly paler ; first joint of 

 posterior tarsi one-half to two-thirds as long again as the second, second 

 longer than the third, third and fourth sub-equal. 



Male. — Posterior edge of the fifth ventral segment transverse in some 

 specimens, just perceptibly sinuate in others, surface neither impressed nor 

 flattened ; sixth segment sinuate at apex, sinus much broader than the 

 apices, evenly rounding, five times as wide as deep ; seventh deeply emargi- 

 nate at tip, bottom of emargination transverse, teeth very long and slender. 



Female, — Sixth segment very broadly angulate at tip; seventh sometimes 

 irregularly and deeply serrate at tip. 



Length, males, 3.0 mm. ; females, 4.0 mm.

Resembles vinnulus, but differs in the pubescence, in the coarser 

 and closer elytral punctuation, and in the sexual characters. 



A specimen of this species affords one of the few instances which 

 I have observed, in which the lingula with the paraglossae has been 

 protruded ; it seems to be an exceedingly rare phenomenon in the 

 American representatives of the genus.
