AMERICAN COLEOPTERA. 123 



male elytra and a narrow space along their sides, not attaining the humeri, 

 are bordered with yellow. The legs are black, except usually the anterior pair 

 and frequently the middle tibiae which are pale testaceous. Length .10 inch; 

 2.5 mm. 



Occurs in the Middle and Southern States. 



A. varum*, n. sp. — Piceous, shining, sparsely pubescent. Head black 

 shining, anterior margin of front testaceous. Antennas brownish testaceous. 

 Thorax broader than long, sides feebly rounded, slightly narrowed to base 

 which is broadly rounded ; color black, shining and nearly smooth. Elytra 

 slightly wider at base than thorax, sides divergent, color piceous, lateral mar- 

 gin, tip and apex of suture pale yellowish testaceous. Body beneath piceous. 

 Legs pale yellowish testaceous, hind femora piceous. Length .08 — .10 inch; 

 2— 2.5 mm. 



In this species the elytra are piceous, the tips pale testaceous with 

 the latter color extending along the suture without involving the mar- 

 gin. In two specimens before me there is in addition to the apical 

 space a juxta-sutural small spot a short distance behind the scutellum. 

 There need be no difficulty in distinguishing this from the forms of 

 scincetus as in the latter the hind angles of the thorax at least are 

 margined with yellow and the livid color of the elytra is reduced to 

 an oblique vitta extending from the humerus to the apex of suture. 

 In one specimen of varians the elytra are entirely piceous except a 

 very narrow lateral and apical margin. 



Occurs iu Texas and Louisiana. Three specimens in the Cabinet of 

 Mr. H. Ulke. 



A. granularis, Er. (Anthocomus), Entom. i., p. 112; Lee. (Attalus), List, 

 p. 54. 



Our smallest species, easily known by its broadly oval form, the 

 elytra of the female being very nearly as broad as long. Color piceous. 

 Legs pale testaceous. Length .04 — .06 inch; 1 — 1.5 mm. 



Occurs only in the Southern States. 



A. morulas, Lee. (Menus), Proc. Acad. 1852, p. 167.— Totally black, shi- 

 ning, and with very little pubescence. The abdomen is piceous, the segments 

 at their margins paler. Legs piceous or black, the anterior pair somewhat 

 paler. Length .10 inch; 2.5 mm. 



This species is widely distributed, occurring from Canada to Dis- 

 trict of Columbia and thence westward to Kansas. 



A. pallifii-ons, iviotsch. (Anthocomus), Bull. Mosc. 1859, iv., p. 408; Lee. 

 (Attalus) List, p. 58. — A more elongate species than the preceding, with the 

 head and thorax alone shining; elytra sub-opaque and with a sooty appear- 

 ance and distinctly pubescent. The anterior margin of front and rarely the 

 hind angles of the elytra are testaceous. Anterior legs pale testaceous, middle 

 and hind femora piceous and their tibiae paler. Length .14 inch ; 3.5 mm.
