Coleopterological Notices, III. 75 



But one species has been described from our fauna, although two 

 are said to be known from Texas. 



Ii. piliferus Champ.— Biol. Cent.-Amer., Coleopt., IV, Pt. i, Nov. 1888, 

 p. 462. 



I have not seen any representative of this species. It is proba- 

 ble, however, from the remarks made by Mr. Champion, that it 

 will ultimately have to be separated from the more typical forms of 

 the genus. 



It is " oblong-ovate, feebly convex, obscure reddish-brown, opaque, 

 above usually of a pruinose bluish-violet, obscure purplish, or green- 

 ish-bronzy tint, the surface somewhat thickly clothed with long erect 

 hairs, and also sparsely pubescent." The antennae are "very long, 

 slender and filiform," and the elytra have "rows of very minute 

 punctures placed upon obsolete striae." Length 6.0-8.3 mm. ; width 

 2.0-3.5 mm. 



STEtfOCHIDUS Lee. 



In this genus the posterior coxae are moderately separated by a 

 short abdominal projection, which is evenly rounded at apex and 

 quite similar to that of Xystropus, the anterior being separated by 

 a rather wide, longitudinally convex prosternal process, which is 

 strongly declivous and gradually attenuate behind. The legs are 

 long and slender, the penultimate joint of all the tarsi strongly 

 lobed beneath, the antepenultimate joint of the anterior and inter- 

 mediate also lobed but less strongly, that of the posterior simple ; 

 these modifications are independent of sex. 



The mandibles are distinctly notched at apex, the two lobes sub- 

 equal. The fourth joint of the maxillary palpi is elongate, more or 

 less recti-triangular, and differs sexually in form as described below 

 under S. gracilis; the last joint of the labial is short and robust, 

 wider than long, with the inner side slightly shorter than the outer. 

 The ungues are moderate in size, the external outline more arcuate 

 near the apex, the latter being finely and acutely produced beyond 

 the pectination, which is long and rather fine, the denticles six or 

 seven in number. 



The general form of the body is elongate and convex, the pro- 

 thorax subcylindrical, the integuments being more or less strongly 

 granulato-reticulate and completely glabrous. The wings are well 

 developed.
