KEY TO EASTERN SPECIES OF TYCHITS. 



a. Beak thick, only feebly diminishing in size from ba c e to apex; scales 



of upper surface all very narrow and hair-like. 



I). Body broadly oval: second joint of funicle but slightly shorter than 



first; larger, 4 4.7 mm. 356. SORDIDUS. 



lib. Body more elongate; second joint of funicle much shorter than 



first, but little longer than third, 

 c. Smaller, 2.3 2.5 mm.; thorax slightly longer than wide. 



357. PICIROSTRIS. 



cc. Larger, 3.5 mm.; thorax wider than long. 358. LILJEULADI. 



art. Beak thick at base, becoming much more slender toward apex; elytra 



with a few scattered rounded scales mingled with the narrow ones;

Oval, convex, robust. Black, densely and uniformly clothed with small 

 slender scales, silvery gray to yellowish in color and slightly more con- 

 densed along the suture. Beak barely as long as thorax, slender, straight, 

 cylindrical, pubescent except at tip, finely and densely punctate, feebly 

 striate. Thorax slightly wider than long, sides broadly and evenly curved, 

 apex scarcely one-half as wide as base; disc deeply and densely punctate. 

 Elytra oblong-oval, much wider than thorax, one-fourth longer than wide; 

 striae well impressed; intervals flat. Hind femora feebly toothed. Length 

 4 4.7 mm. 



Ranges from Illinois and Iowa to Louisiana and Texas. 

 Pierce states (1007, 27:>) that in the latter states it breeds in 

 the seed pods of the wild or false indigo, liii/tti.^in hr<i<-/c<it<t FA]., 

 and B. lciif<intJiu T. & G. The larva 1 eat the pod clean, then eat 

 their way out and pupate in the ground. Many scattered scales 

 of the elytra an 1 glistening metallic yellow.

Differs from typical sordid us in having the thorax notably smaller, the 

 sides less rounded and more rapidly converging from base; scutellum
