AMERICAN COMPONENTS OF THE TENTYRIIN^ 429 



short, fine, decumbent, yellowish and inconspicuous pubescence; 

 head small, fully half as wide as the prothorax, slightly wider 

 than long, rather finely and not densely punctate ; prothorax 

 small, two-fifths wider than long, the apex feebly sinuato-truncate 

 and fully three-fourths as wide as the base, with the angles very 

 obtuse and somewhat blunt; disk widest at the middle, where the 

 sides are prominently rounded, thence strongly converging and 

 straight apically and but little less converging and straight to the 

 basal angles, which are more than right and very slightly blunt, 

 the sides acute but not at all margined or reflexed ; surface convex, 

 feebly impressed on the basal lobe and midway between this and 

 each side, rather finely, very sparsely punctate, becoming less 

 finely but still not very closely laterally, with an impunctate line 

 medially only toward base; elytra fully three-fourths longer than 

 wide, three and one-half times as long as the prothorax, and, at 

 the middle, nearly one-half wider, gradually and arcuately nar- 

 rowed behind to the ogival apex, the sides broadly arcuate to the 

 rounded humeri, which are transversely exposed at base; surface 

 with one or two impressed lines along the suture, especially 

 behind, finely, sparsely punctate and but little less finely or sparsely 

 toward the sides, the punctures confused, with feebly defined and 

 incomplete series of similar punctures here and there; abdomen 

 finely, sparsely punctate even toward the sides, with similar very 

 short, sparse and inconspicuous hairs. Length 7.5 mm.; width 

 2.9 mm. Florida (Tampa) puberulus Lee. 



The original unique type of -ptthcruliis was described from 

 Georgia, and is said to have the elytra more than four times as 

 long as the prothorax and with a faint metallic gloss ; consider- 

 ing these differences, in connection with the inconspicuous pubes- 

 cence of the Tampa representative, it is possible that there 

 may be two distinct species involved. The sex of the specimen 

 described above is not determinable. 



Concecus Horn. 

 In this genus the sides of the prothorax are completely devoid 

 of beaded or reflexed edge, as in Schceiiictis, the edge being 

 obtusely rounded in section and punctate. The body is oval, 

 the head, mandibles, mentum and antennae as in Schcvniais, but 

 the eyes are a little less developed and, though similarly coarsely 

 faceted and without trace of supra-orbital carinse, are much 

 flatter and not at all prominent. The prosternum between the 

 coxae is convexly declivous behind them as in Sc/uvnicus, but the 

 intercoxal part of the mesosternum is tumid and its steep ante- 

 rior slope is more or less deeply impressed as in Epitragodes.
