Easily distinguished by its .small size, intense black color, and red leijs. 

 It seems to be rather uncommon, only one or two specimens from anv 

 one locality beiuir received.

 This group contains three very closely allied species, distinct by the 

 broad, almost .square elytra, and by the very den.se whitish pubescence on 

 two of its species. They are separated as follows : 



Densely pubescent. 



Legs red. 2—2.5 mm segnipe!^. 



Legs black, humeri of elytra not elevated, 2 — 2.5 mm griseiim. 



Sparsely pubescent, humeri of elytra elevated, 2 — 2.5 mm rraieriium.

 Stet. Ent. Zeit.. 1854. 250. — Black, antennae except club, and legs except knees and 

 tarsi, pale reddish : so densely clothed with white pubescence as to give the inse<!t 

 an ashy gray appearance. Head elongate, closely punctured, eyes not prominent; 

 antennae moderate, basal Joint one-lialf longer than second, and as thick : rostrum 

 moderate and slender. Thorax much wider at base than at apex, widest just 

 before the base, densely punctured, and with a median impressed line, distinct at 

 base, but obsolete before the middle. Elytra but little longer than wide, sides sub- 

 equal, striae narrow, punctures distinct, intervals wide, flat and scabrous. Beneath 

 grossly and evenly punctured. Length 2 — 2.5 mm. 



Ilab. — Western and Southern States. 



Varies soiuewhat in size, in the density of the pubescence, and in 

 color of legs, but always easily recognizable. It is common where it 

 occurs. Say describes it as in seeds of Astralagvx. Riley says it is 

 found in seeds of Tcphrosia virginica. Astragalus. 



A. griseiiin n. sp. — Black, densely pubescent. Head as in the preceding, a 

 distinct sulcus from base to middle of rostrum; antennae rather short and heavy, 

 thorax and elytra as in the preceding, striae distinct, punctures evident, intervals 

 narrow, flat and finely punctured. Beneath finely and densely punctured. 

 Length 2 — 2.5 niin.

Of the .same general form and appearance as the preceding, and with 

 similar pubescence, but at once distinct by the black legs. The insect
