outer -very small and feeble. Elytra about }4 longer than wide, more than 

 twice as long as the prothorax and about twice as wide, ovoidal, very convex, 

 widest at or slightly behind the middle, the sides strongly convergent and 

 nearly straight to the base, broadly rounded behind ; humeri almost obsolete, 

 the basal impression indistinct ; subsutural impressions slightly visible toward 

 base. Pygidiiim equilatero-triangular, finely reticulato- scabrous toward base. 

 Legs long, the femora very strongly and abruptly clavate. Length 2.0 mm. ; 

 width 0.8 mm. 



Central Illinois. Mr. Webster. 



The description is taken from a specimen having the sixth 

 ventral much shorter than the first ; another, which has this seg- 

 ment distinctly longer than the first, has the head visibly less 

 transverse and more strongly narrowed behind ; I regard the lat- 

 ter as the male, and, in this example, the anterior tarsi are feebly 

 dilated toward base. 



This species differs from longicollis in its much shorter pro- 

 thorax, widest near the middle and less narrowed anteriorly, in 

 its slightly stouter antennae and still more inflated hind body ; it 

 is however ver}^ closely allied both to that and to the following 

 species. 



10. Eu. sagiiiatus n. sp. — Stout and rather strongly ventricose, pol- 

 ished, impunctate, the body, legs and antennae very pale flavo-testaceous 

 throughout ; pubescence short, stiff and distinct on the head, sparse and longer, 

 but very inconspicuous on the pronotura, long, sparse, erect aod bristling on 

 the elytra. Head moderate in size, distinctly wider than long behind the 

 antennse, circularly rounded and convergent at the sides from the eyes to the 

 neck ; eyes moderate in size, not at all prominent ; upper surface convex, 

 minutely and feebly but closely punctulate, the frontal projection densely and 

 distinctly punctato-scabrous. Antennie fully % as long as the body, the club 

 narrow, long and feebly incrassate ; basal joint much stouter than the follow- 

 ing, enlarged and deeply excavated at apex, barely twice as long as wide and 

 scarcely longer than the next two ; second to fourth subequal, only slightly 

 longer than wide ; fifth feebly obconic, not more than }4 longer than wide, a 

 little thicker than the preceding but as wide as six to eight, which are short, 

 oblique and deeply excavated within at apex as usual ; ninth as long as the 

 two preceding and % wider, not longer than wide ; tenth a little thicker, sub- 

 oval with truncate base, rather longer than wide ; eleventh long, gradually 

 and obliquely pointed, rather thicker, barely as long as the two preceding. 

 Prothorax barely as long as wide, nearly '}-{ wider than the head, widest and 

 more strongly rounded well behind the middle, the sides thence rather 

 strongly convergent and nearly straight to the base, convergent and feebly 

 arcuate to the apex, which is broadly arcuate and quite distinctly narrower 

 than the base ; disk convex, impunctate, finely scabriculate along the base, 

 feebly swollen at the middle near the basal margin, and with one small sub-
