ERIRIUNINI. 177 



common brown cloud extending from the base thee-fourths the length; 

 suture for the same distance blackish; beneath dirty gray. Length 2.3 

 mm.; .09 inch. 



Two specimens, Texas: Mr. Belfrage. Tarsi as in the preceding species. 

 In some specimens the variation in tint is scarcely apparent, and the whole 

 upper surface is of a dull golden color. 



5. E. cribricollis, n. sp. 



Blackish brown, covered with grayish scales; prothorax subquadrate, 

 scarcely wider than long, sides nearly straight, a little rounded near the 

 tip, which is constricted ; surface very coarsely and deeply punctured. 

 Elytra suddenly one-third wider than the prothorax, humeri rounded, 

 striae deep, slightly punctured, interspaces nearly flat, disc with a faint 

 brownish cloud behind the middle. Length 2.3 mm. ; .09 inch. 



One specimen, Georgia. The last tarsal joint is a little shorter, and the 

 claws smaller than in the preceding species. 



6. E. punctatus, n. sp. 



Smaller and more robust than E. cribricollis, with the prothorax wider than 

 long, more deeply constricted at tip, and somewhat less coarsely punctured. 

 Elytra a little wider than the prothorax brown, with a darker sutural 

 stripe ; stria3 deep, more distinctly punctured ; legs dark testaceous. 

 Length 1.8 mm. ; .075 inch. 



One specimen, Texas; Mr. Belfrage. The last tarsal joint and the claws 

 still smaller than in E. cribricollis. 



7. E. ovalis^n. sp. 



Almost regularly oval, black, mottled with pale gray scales. Prothorax 

 wider than long, narrowed from the base forwards, rounded on the sides, 

 strongly constricted at the tip, surface deeply but not coarsely punctured, with 

 three pale vittse. Elytra very little wider than the prothorax; gray, with a 

 abbreviated sutural stripe, and frequently some mottlings of dark brown ; 

 striae deep, feebly punctured. Length 2.3 mm.; .09 inch. 



New York and California. The color depends on the extent to which 

 the crust of gray scales is preserved. 



Several much smaller specimens from California, Florida and Lake Sup- 

 erior have the prothorax comparatively more coarsely punctured, but do not 

 show any other difference. Length 1.5 mm. ; .06 inch. 



TANYSPHYRITS Sch. 



This genus barely differs from Endalus by the funicle of the antennse 

 more slender, with the joints scarcely increasing in thickness; the pro- 

 thorax narrower, and scarcely rounded on the sides; and the elytra fully 

 one-half wider than the prothorax, truncate at base, with the humeri more 

 prominent and slightly oblique. The last joint of the tarsi does not pro- 

 ject beyond the lobes of the third, and the claws are distant and divari- 

 cated as in Endalus. 



As Lacordaire observes, it resembles in miniature a Orypidius.
