wider than long, parallel and straight at the sides, the apex broadly arcuate; 

 base broadly arcuato-truncate; disk feebly impressed along the median line 

 toward base, rather finely but strongly-, not densely punctate. Scutellum 

 relatively small. Elytra large and long, two-thirds longer than wide, nearly 

 twice as wide as the prothorax, parallel and broadly arcuate at the sides, 

 gradually narrowed and not very broadly rounded in apical third; humeri 

 widely rounded externally, well exposed at base; disk impressed at the suture 

 near the apex, the subhumeral impression very short and feeble; punctures 

 rather coarse but well separated, becoming graduallj' much smaller toward 

 apex. Abdomen finely, sparsely punctured, the legs somewhat long, the pos- 

 terior thighs moderately incrassate; basal joint of the hind tarsi very long and 

 giadually bent toward base as usual. Length 2.5 mm. ; width 1.15 mm. 



Iowa (Iowa City). Mr. Wickham. 



The two specimens serving as types are apparently females, 

 with the fourth ventral one-half longer than the third, and having 

 a rounded central setiferous foramen, the inner surface at apex 

 with a series of about twelve small setiferous spicules, which are 

 inwardly erect, the inner surface of the dorsal plate with three 

 large lamelliform teeth at the middle of the apical margin and 

 projecting inward. 



This species is the largest of the genus, and, though allied 

 closely in general appearance to fasciatus, ma}- be distinguished 

 b}' its more elongate elytra, smaller scutellum, larger size and 

 other characters.

Piceous-black throughout, shining ; pubescence long and con- 

 spicuous. Elytral punctures rather coarse, strong and close-set 

 throughout, separated by more than their own widths at basal 

 third, denser toward base, finer and sparser toward apex. Prono- 

 tum not impressed, convex; antennae thick, three-fourths as long 

 as the elytra. Length 2.3 mm.; width 0.85 mm. 



Texas (Waco). I am not at all sure of the generic position of 

 this species, the above hast}' notes having been taken from the 

 unique t^^pe, which is now inaccessible. From an outline sketch 

 made at the same time, the eyes appear to be much smaller than 

 usual in this genus, and are at some distance from the base, and 

 the prothorax is gradually' narrowed behind from near the apex, 

 which is also a character foreign to the other species.

 The small subequal second and third joints of the antennje will 

 readily distinguish the two members of this genus, and the fol-
