toothed on the inner side ; eyes rounded, finely granulated. The antennae 

 are half as long as the body; first and second joints a little stouter, and 

 nearly equal ; 3-8 longer, shining ; ninth of the same length, gradually 

 thicker externally and sensitive ; tenth about one-third shorter, oval, 

 longer than wide, sensitive; eleventh elongate-ovate, pointed, as long 

 as the ninth and sensitive ; these joints are not compressed, and form an 

 elongate loose club. Mentum with the lobes narrowly rounded, and sub- 

 acute. Prothorax very uneven with large approximate foveae ; broadly 

 transversely impressed before the middle ; antebasal ridge nearly straight, 

 about one-fifth from the base, which is strongly biemarginate for the re- 

 ception of the bases of the elytra ; at the sides, the ridge is bent at an 

 obtuse angle, and descends obliquely, forming an obtuse lateral protuber- 

 ance about the middle ; in front of this the prothorax is gradually ob- 

 liquely narrowed. The elytra are wider than the prothorax, uneven with 

 short transverse rugosities and elevations; striae composed of large distant 

 punctures ; base separately rounded and finely margined, not excavated 

 near the scutelluni, but obtusely elevated from the first to the fifth stria. 

 The alternate interspaces are wider and more convex. The first joint of 

 the tarsi- is long, the second triangular and emarginate ; third not narrower 

 than second, bilobed ; claws toothed at the middle. First and fifth ventral 

 segments longer than the others.

Northern States, Canada, Vancouver's Island. A large species con- 

 spicuous by the beak and a broad transverse band behind the middle of 

 the elytra being clothed with snow-white hair. Length 6.5-9.5 mm.; .25-. 37 

 inch.

New York, Wisconsin. A small, rather slender species, easily known 

 by the white humeral spot and transverse subsutural spot behind the mid- 

 dle; the beak is broad, not longer than the head; the prothorax is feebly 

 and obtusely tuberculate at the sides. The eyes are more widely separated, 

 and more oblique than in the two preceding genera, The antebasal ridge 

 is obtusely angulate at the middle with the angle directed forwards, and 

 obtusely flexed on the sides. Length 4.7 mm. ; .18 inch. 



Gemminger and Harold have incorrectly referred A. cornutus Say to this 

 genus; it will be found below under Anthribus. 



2. T. rectus, n. sp. 



Oval-cylindrical, dark brown, with spots of yellow pubescence, and upon 

 the elytra also a few white dots. Head and prothorax opaque, very densely 

 and rather finely punctured; antebasal ridge nearly straight and parallel 

 with the base, suddenly flexed at the sides, and extending nearly to the
