Length 56.5 mm. Densely scaly, usually brown or tan with Slightly golden 
luster, occasionally mostly gray, the pronotum with a very broad but indefinite 
median stripe, and a narrower lateral stripe, brownish, and a pale to whitish 
stripe on flank opposite elytral humerus. Elytra with sutural brownish stripe, 
at least basally, and usually with some indefinite and irregular brownish mot- 
tlings which are more pronounced laterally, sometimes largely brownish with 
a paler, longitudinal area on disk of each elytron; scales paler and denser and 
forming a short basal, and a longer apical, stripe on interval 9, and a rather 
conspicuous lateral str-pe opposite abdominal sternites 1 and 2.. 
Head broad, vertex not prominent, setae subprostrate; eye very prominent, 
scales around eye and on side of rostrum below scrobe paler than those on 
dorsum; rostrum strongly tapering, above with forwardly inclined setae, median 
groove sharply defined and not, or slightly, widened anteriorly, nasal plate 
feeble, mandibles each with a fine carina from lower, mesal edge of scar to 
lower edge of mandible; scape slightly passing eye. Prothorax with sides 
broadly, feebly rounded, hind margin in side view scarcely angulate opposite 
elytral humerus; pronotum with median groove obsolete, basal margin broadly 
rounded. Scutellum broadly to narrowly triangular, glabrous. Conjoined elytra 
feebly emarginate basally, surface with a slight thickening or prominence at 
humerus so that side of elytron has a feeble posthumeral emargination (fig. 5, 
D); puncture rows 1 to 4, especially row 2, more or less bent laterad near base; 
intervals flat to feebly convex, each with a confused double or triple row of 
setae which are subprostrate and indistinct on disk but inclined to suberect 
on declivity, those on interval 1 a little longer and more crowded than else- 
where; interval 1 usually slightly prominent. Under side and legs rather 
finely setose and densely scaly; metepisternum long, its suture usually obscured 
by scales medially. Denticulations on fore tibia unusually slender and short, 
mucro on middle tibia minute, corbel plate narrow, the dorsal comb longer than 
distal. Spermatheca contorted and greatly elongated (fig. 4, A). 
Type locality—Missouri (banks of the Mississippi River and lower 
part of the Missouri River). 
Iistribution—Ulinois (Nashville); Missouri (Charleston, one 
specimen reared from Elymus virginicus, Virginia wild-rye, by A. F.
