12. T. fiilvipcs, Er. Staph. 804.

1.3. T. inomnoiiiiis, Er. Staph. 806. 



Described from E^ypt; identified by Mr. Fauvel, among specimens 

 from the Southern States. 



APOCELI.US Er. 



The species of this genus resemble in form Falagria of the Aleo- 

 charini, but are easily known by the three-jointed tarsi, and the inser- 

 tion of the antenna) under elevated frontal ridges. The species are 

 few in number, and easily distinguished; others occur in the Antilles 

 and South America, but not on the eastern continent. 



So flxr as I have collected them they are found in cow dung, and in 

 decomposing vegetable material.

Head and prothorax opake; head large, truncate behind, prothorax trape- 

 zoidal 1. stilieoi(Ie!<i, n. sp. 



2. — Sides of head oblique and rounded behind, base but slightly truncate; pro- 

 thorax rounded or nearly so 3.

1. A. !i»tiIicoi(1et<, n. sp. — Piceous, head and prothorax opako, finely 

 alutaceous; base of antennse and legs yellow-testaceous. Head large, feebly 

 convex, sides parallel behind the eyes, base broadly truncate, hin<l angles 

 rounded ; frontal suture well-marked; vertex with a very short im]iressed line. 

 Prothorax not very convex, narrower than the head and elytra, broader than 

 long, trapezoidal with rounded angles, narrowed from the front to the base, 

 which is scarcely margined ; disc with a very obsolete short dorsal elevation. 

 Elytra shining, convex, very finely punctulate, and thinly clothed with ex- 

 tremely short pubescence. Dorsal segments punctulate, almost as the elytra; 

 ventral segments also punctulate, more distinctly jiubescent. Length 2 mm; 

 .08 inch. 



%. — Sixth ventral very slightly emarginate at the middle; seventh not pro- 

 longed, (almost invisible in my specimen). 



9. — Sixth ventral not emarginate; seventh triangularly produced, as in all 

 the other species. 



One pair, Knterprize and Baldwin, Florida; iMessrs. Hubbard and 

 Schwarz. This species by the opacity of part of the surface is re- 

 lated to the Amazonian A. 'planus, Sharp, Trans. Ent. Soc. London, 

 1876, 401. 



2. A. analis, n. sp. — Rufo-testaceous, shining, smooth, last two dorsal seg- 

 ments of abdomen blackish. Head large, sides parallel behind the eyes, broadly 

 truncate at base, hind angles rounded. Prothorax convex, wider than long, 

 narrowed from the front angles to the base, sides straight, angles rounded, base
