Coleopterological Notices, V. 581 



Certain features of the under surface of this genus are suggestive 

 of the Histeridae. The glabrous intermediate tibiae and tarsi do not 

 seem to have been referred to in the books. 



PELONOHUS Erichs. 



The species of this genus are few in number; the one described 

 below is closely allied to obscurus, but is shorter, broader and paler 

 in color. 



P, mfescens n. sp. — Dark red-brown, stout, convex, densely clothed 

 with very short coarse hairs and less densely with longer erect setae, the punc- 

 tures fine but strong, extremely dense on the head and pronotum, less dense 

 on the elytra, the latter with very feeble longitudinal impressed lines. Head 

 two-thirds as wide as the pronotal base ; eyes large, convex and prominent, 

 densely setose ; antennae nearly as in obscurus. Prothorax one-half wider than 

 long, the sides feebly convergent from base to apex, broadly, feebly arcuate, 

 just visibly sinuate near the basal and apical angles, the latter acute and 

 anteriorly prominent ; disk evenly, rather strongly convex ; apex subtruncate, 

 the base broadly, strongly bisinuate and also emarginate at the scutellum. 

 Scutellum transverse, obtusely angulate behind. Elytra barely twice as long 

 as wide, a little more than three times as long as the prothorax, acutely ogival 

 behind, the suture broadly and feebly impressed on the posterior declivity. 

 Under surface paler, the three pairs of coxse separated by exactly the same 

 distance. Legs moderate, the tibial spurs short, stout, widely separated ; 

 tarsi slender, the posterior two-thirds as long as the tibiae. Length 5.5-6.3 

 mm. ; width 2.3-2.5 mm. 



Florida. 



Readily separable from obscurus by the more obese form, more 

 widely separated middle coxse, more transverse and much more 

 broadly angulate scutellum, and by the very narrow and not 

 broadly angulate apical prosternal fissure behind the eyes. The 

 type is a female; the male has the last joint of the anterior tarsi 

 very feebly dilated but scarcely as strongly so as in obscurus. 



OBERONUS n. gen. 



Eyes, palpi and general structure nearly as in Pelonomus. In- 

 termediate coxse large, subglobular, contiguous, the metasternum 

 forming an acutely elevated transverse and feebly arcuate ridge 

 behind them, the mesosternum a transversely tumid, deeply and 

 anteriorly excavated process before. 



0» Ob.esiis n. sp. — Broadly oblong-oval, convex, black ; palpi, tibiae, tarsi 

 and abdomen toward apex rnfescent, densely clothed with very short stiff
