sculptured and tuberculate. The thighs are slightly clavate, sinuate 

 beneath near the tip, and armed with a small tooth. The tibiae slightly 

 curved, not very stout, not compressed, strongly sinuate on the inner side, 

 and serrate from the middle to the tip. The first joint of the funiculus is 

 longer than the second ; 2-7 gradually a little stouter, rounded in form ; 

 club small, oval pointed, pubescent.

The^ is smaller and narrower than the 9 an d has the abdomen broadly 

 and deeply concave in front. The color is blackish brown, and in well 

 preserved specimens the elytra are mottled with spots of yellow-brown 

 small narrow hair- like scales. Length 6-9 mm ; .24-. 43 inch. 



HYPOMOLYX n. g. 



Body elongate, ovate, broader behind, proportioned nearly as in the 

 Alophidae ( Thricalophus) . Beak as long as the prothorax, rather stout, 

 slightly curved, coarsely punctured with deep triangular anteocular 

 groove at the side, and three faint carinse above ; antennal grooves ex- 

 tending to the lower edge of the eyes, which are transverse, rather small, 

 and not very finely granulated. Prothorax without postocular lobes, pro- 

 sternum broadly emarginate in front, and fringed with long yellow cilise. 

 Mesosternum as long as the first ventral segment. Ventral segments less 

 unequal than in the other genera ; fifth but a little longer than fourth ; 

 first suture obtusely angulated at the middle. Thighs scarcely clavate, 

 sinuate beneath near the tip, not toothed ; tibiae slender, feebly sinuate on 

 the inner side, armed with a strong apical hook. The first and second 

 joints of the funiculus are elongate and equal,! 3-6 rounded, shorter; seventh 

 broader and larger, almost forming part of the club, though less so than 

 in Hylobius.

Lake Superior, Hudson Bay Terr., Canada. Mentioned by me in 

 Agassiz Lake Superior, as Hylobius heros, but not described. A fine species, 

 with the prothorax rather small, sub-serrate on the sides, very coarsely 

 punctured, thinly clothed with coarse hair, carinate in front ; the elytra 

 densely punctured, mottled with small spots of yellow hair; striae composed 

 of large elongate deep punctures. Length 13.5 mm ; 5.3 inch. 



PACHYLOBIUS n. g. 







I have separated as a distinct genus Hylobius picivorus, which differs 

 greatly from the other species by the tibiae being much shorter and stouter, 

 and expanded at the tip, so that the corbels or surface included by the double 

 edge on the outer apical margin is much wider than in the other genera 

 of the tribe. The beak is as long as the prothorax, rather stout, not curved, 

 feebly fculcate in front of the eyes, antennal grooves attaining the middle
