LeConte.] CRYPTORHYXCHINI. 245 



nietathoracic side pieces of Cryptovhymlius. The last joint of the tarsi 

 is rather longer, and the claws somewhat larger than in the other species of 

 Acalles; the beak is also more slender and differently sculptured. A revis- 

 ion of the tribe with careful study of the exotic forms will prol)ably show 

 the proprietj' of placing this species as a distinct genus. 



. 13. A. pectoralis, n. sp. 



Robust, black, covered with depressed scales of dark brown color, varie- 

 gated with pale on the elytra, forming narrow, undulated bauds, and on the 

 protliorax indistinct stripes; intermixed bristles stout, short, erect. Anteunaj 

 testaceous. Beak coarsely punctured, linely carinate, scaly, tip naked; 

 liead scaly like the beak, front not impressed. Prothorax wider than long, 

 convex, much rounded on the sides, distinctly constri ted in front, chan 

 neled. Elytra much rounded on the sides, striae deep and fine, interspaces 

 wide, slightly convex. Body beneath densely but less coarsely punctured, 

 clothed with yellowish brown scales; mesosternum very broadly emargi- 

 nate. Legs annulated. Length 3 mm.; . 12 inch. 



One specimen, Illinois. Quite distinct from all the others by the less 

 emarginate mesosternum, and the depressed scales of the prothorax and 

 el^'tra. It is possible that these differences should be considered as generic, 

 l)ut I am unwilling to so regard them without a careful study of foreign 

 species. 



EURHOPTUS n. g. 



I have separated as a distinct genus a small pyriform, robust species, not 

 scaly, but thinly clothed with reclinate bristles, in which the metasternum 

 is very short as in Acalles, but which difters essentially by the club of the 

 antennae ; this is stouter, less elongate, and annulated only near the tip; 

 the funicle is 7-jointed; the second joint a little longer than third, 3-7 

 equal, short, closely united. Beak stout, as long as the protliorax. Meso- 

 sternum horizontal, emarginatiou broad, with acute edge. First ventral seg- 

 ment longer than metasternum, with a deep, polished triangular impres- 

 sion; intercoxal process triangular; second segment shorter than third and 

 fourth united; fifth as long as the three preceding united. Thighs not 

 toothed, tibiae slender, straight, mucronate at tip; tarsi with third joint 

 broadly dilated; foitrth small with very small, approximate claws. Elytra 

 connate; scutellum not visible. ' 



1. Eu. pyriformis, n. sp. 



Robust, pear-shaped, convex, dulh black, thinly clothed with pale, recli- 

 nate curved bristles. Beak stout, rather depressed, finely punctured, naked 

 at tip, subcarinate; eyes small, depi-essed, front not impressed; antennae 

 brown. Prothorax not wider than long, narrowed from the base, sides 

 straight, base nearly straight, disc densely and coarsely punctured, feebly 

 transversely impressed at a distance from the tip. Elytra fitting closely to 

 the prothorax, strongly rounded on the sides; striae composed of verj' large, 

 rather distant foveae; interspaces near the suture somewhat convex. Length 

 less than 2.5 mm. ; .10 inch.
