5G4 Coleopterological Notices^ VII. 



Prothorax shorter, not longer than wide, less rounded at the sides anteriorly, 



the apex but slightly narrower than the base laevis n. sp. 



Prothorax narrower, fully as long as wide, the sides more arcuate and the apex 

 somewhat narrower when comxiared with the base. 

 Front obtusely rounded between the antennse ; cephalic fovese small and 



subperforate convexula Leo. 



Front more narrowly subangulate, the head more puuctulate toward the 

 sides ; fovese larger, more widely impressed and rather less remotely sepa- 

 rated ; pubescence a little coarser dubia Lee. 



The characters of the table are drawn from the female through- 

 out. The genus is confined, so far as known, to the Atlantic 

 coast regions. 



T. laevis. — Strongly convex, highly polished, impunctate and uniformly 

 pale flavo-testaceous throughout, moderately ventricose, the pubescence very 

 fine, short, decumbent and rather inconspicuous though somewhat abundant. 

 Head rather large, fully as wide as the prothorax, almost as long as wide, 

 feebly convex, the eyes very small, slightly prominent, at nearly twice their 

 own length from the base, the tempora less prominent behind them, long, 

 feebly convergent and but slightly arcuate to the basal angles, which are ob- 

 tusely rounded ; occiput not visibly impressed ; foveas slightly behind the 

 middle, large, separated by more than }4 the entire width, the ambient sulcus 

 large but shallow, becoming lost anteriorly in the shallow depression between 

 the moderate antennal prominences, the sulcus with some scattered coarse 

 punctures near the prominences ; antennse ^ longer than the head, the last 

 joint very large, conoidal, almost as long as the .-ix preceding joints combined. 

 Prothorax as long as wide, widest but not very prominently rounded at the 

 middle, the sides thence feebly convergent and broadly arcuate to the apex, 

 more rapidly so and sinuate to the base ; transverse sulcus deep, strongly an- 

 gulated at the middle, continued down the flanks. Elytra di.-tinctly shorter 

 than wide, nearly as long as the head and prothorax and about ^ wider, the 

 sides divergent from the slightly prominent humeri to the apex and rather 

 strongly, evenly arcuate ; intra-humeral fovea deep, vanishing at about basal 

 fourth ; sutural stria fine. J ftrfomew slightly narrower and somewhat longer 

 than the elytra, the sides feebly convergent and slightly arcuate, the apex 

 parabolic ; first dorsal nearly as long as the next two, with two slender 

 parallel basal carinse }4 or }4 as long as the segment and separated by % the 

 entire width ; second ventral rather longer than the next three combined, with 

 two slender parallel basal carinse nearly }{ as long as the segment. Legs and 

 tarsi slender, the femora but slightly inflated in the female. Length 0.8 mm. ; 

 width 0.35 mm. 



District of Columbia, 



This species is allied to convexula, which was described from 

 Tampa, Florida, my representative being from Crescent City. It 

 differs from convexula, as compared in the female, in its rather
