176 J. L. LECONTE, M. D. 



behind; base reddish-brown; a narrow acutely anejulated transverse band of 

 sericeous pubescence about the middle, and a similar cloud near the tip; sur- 

 face coarsely and densely punctured. Antennae rather atout, hairy. Tarsi 

 yellow. Length 2.5 mm.; .10 inch. 



%. — Hind thighs thickened, fringed beneath and broadly toothed; middle 

 tibi» bent, first joint of midille tarsi fringed; last joint of anteiinre as long as 

 |he three precedin? unite<l, but not wider; eyes large, front narrow. 



9' — Legs simple; antennae gradually but strongly thickened externally, 

 last joint but little longer than the preceding, pointed at tip; eyes smaller^ 

 front wider. 



Pennsylvania; Louisiana. Closely related to X. basalts, but the 

 prothorax is of a different form ; the basal redness of the elytra is 

 ill defined, and the angulated sericeous band, of which there is no 

 trace in X. hasalis is quite distinct. The sexual characters are alike 

 in the two species. 



Xylophilus siibras^ciatas.— Pale testaceous, thinly pubescent; head 

 and prothorax finely punctured, the former dusky. Prothorax subquadrate, 

 broader than long, feebly channeled towards the base. Elytra one-half wider 

 than the prothorax, oblong, less elongate, rounded behind, strongly but not 

 coarsely punctured ; they are marked with a blackish spot near the suture and 

 another at the side margin. Antennae stout, joints turbinate, hairy. Length 

 1.6 mm. ; .07 inch. 



%. — Antennae with the eleventh joint as long as the two preceding. 



9- — Antennae with the eleventh joint broader, ovate, acuminate. 



Middle, Southern and Western States. In one specimen the elytra 

 are deeply transversely impressed at the middle. The eyes are widely 

 separated and the front is wide in both sexes. 



Xylophilu^ brunnipennis. — Dark-brown clothed with cinereous pu- 

 bescence. Head and prothorax finely and densely punctulate, the latter wider 

 than long, sides rounded in front, apex rounded; disc convex, with a transverse 

 impression near the base. Elytra one-half wider than the elytra, oblong, sides 

 parallel, rounded behind, testaceous, finely and deeply punctured, obliquely 

 impressed near the base. Antennae stout, scarcely thicker externally, eleventh 

 joint ovate, acute at tip. Length 1.8 mm.; .07 inch. 



S. Carolina, (Zimmermuun) ; Illinois, (Walsh) ; Texas, (Belfrage). 

 I observe no sexual differences in the three specimens I have ex- 

 amined. 



Xylopliilns ventricosas. — Smoky brown, densely punctured, varied 

 with angulated lines and spots of pale yellow. Prothorax nearly twice as wide 

 as long, sides straight, hind angles obliquely emarginate. Elytra twice as wide 

 as the prothorax, ventricose. Antennae slender, pale, outer joints a little thicker ; 

 tibiae and tarsi pale. Length 1.8 mm.; .07 inch. 



Southern Suites, two specimens. The pale markings of the head, 

 prothorax and elytra are (juite complex, and dilhcult to describe, but 

 the peculiarly large and inflated elytra will enable the species to be 

 easily recoguized. The eyes are smaller, and the front wider than 

 usual.
