654 Coleopterological Notices^ VII. 



exposed connective membrane, the first as long as the next two 

 the last four gradually diminishing in length. Legs short and very 

 stout ; femora much swollen throughout but especially the arite- 

 rior; tibise short and stout, obliquely truncate at tip, apparently 

 without terminal spurs ; tarsi short and stout, 5-5-4-jointed, the 

 last joint as long as the I'emainder in all, the anterior pair very 

 broadly dilated and densely clothed with stiflT yellowish hairs be- 

 neath ; claws rather stout, well developed, arcuate, simple and 

 divaricate. 



The single species assignable to this genus, the relationship of 

 which seemed rather difficult to determine at first, is small and 

 quite insignificant in appearance, and was forwarded to me by Mr. 

 H. F. Wickham as one of his captures in the delta region of the 

 lower R.io Grande. 



A. crinita n. sp. — Parallel, subcylindric, feebly depressed above, shining, 

 dark rufo- testaceous and somewhat sparsely clothed throughout with moder- 

 ately long, stiff, erect hairs; legs and elytra brighter rufous, ffead subdeflexed, 

 fully as long as wide, cylindrically and evenly convex above, strongly punc- 

 tate, the punctures slightly elongate, well separated but closer and subrugose 

 near the sides of the front; eyes at nearly twice their length from the pro- 

 thorax; anteunse as long as the prothorax, sparsely bristling, the first joint 

 globularly enlarged to some extent. ProtJiorax as long as wide, very feebly 

 narrowed and with slightly arcuate sides from apex to base; apex transverse, 

 feebly arcuate toward the angles, which are not prominent; basal angles ob- 

 tuse; surface subcylindrically convex, even, the basal margin depressed 

 beneath the general surface; punctures deep, strong, moderately coarse, dis- 

 tinctly separated, becoming slightly elongate toward the sides, the marginal 

 serrulation exceedingly fine, feeble and obtuse. Scutellum flat, moderately 

 small, transversely oval. Elytra parallel, with the sides straight, semicircu- 

 larly rounded at tip, f^ longer than wide, 2}^ times as long as the prothorax 

 and fully }^vfideT; base truncate, the humeri feebly tumid, slightly more 

 than right but forming a distinct angle; surface feebly flattened toward the 

 suture, coarsely, deeply and irregularly punctate, the punctures becoming 

 gradually smaller behind, well separated throughout. Length 2.15 mm.; 

 width 0.63 mm. 



Texas (Brownsville). 



No note concerning the habits of this interesting species has 

 been received as yet, but it is probably predaceous like Othnius.
