tra deeply concave, slightly hairy, boundad by a sharp edge, from the tii) 

 for nearly two-tliirds its length; this edge terminates in a cusp at the ante- 

 rior end; the three small d_'nticles at the upper margin of the declivity are 

 much stronger than in the rj*. Head slightly convex, not friiiged with 

 hairs, coarsely punctured, li.iely rugos:^ and opaque near the tip.

9- Club of antenniB not fringed; declivity of elytra refuse at the side, 

 deeply concave towards the suture, with an acute cusp in the concavity 

 each side, about equidistant from the sutura and the apex, which is acutely 

 and strongly margined. Head flat, opaque. (^ unknown. 



One 9, Middle California, given me by Dr. florn. The posterior half of 

 the prothorax, the antennfe and legs are yelUiw-testaceous; the rest of ilu 

 body is blackish brown. Length 3 mm.; .08 inch.

(J'. Club of antennae with a long apical spine, and a few hairs; declivity 

 of elytra oblique, not retuse at the sides, acutely margined only at the apex, 

 and for a short distance behind; face of declivity with a slight reniform ele- 

 vation rising into two cusps near the suture, which is deeply impressed and 

 excavated at that place; head^flat, opaque, not fringed with hairs. 



9. Club of antennae without apical spine; declivity of el3'tra as in rT.but 

 with the reniform elevation and its two cusps much stronger; head slightly 

 convex, sub opaque, feebly punctured. 



Lake Superior to Florida; depredates on apple trees. Length 2 mm. ; .08 

 inch. By a typographical error I cited Dr. Fitch's Second Report for this 

 species.

Under this name I would associate most of the species which I formerly 

 called Cryphalus, but which differ from Cryphalus tilm by having the 

 sutures of the antennal club transverse, nearly straight and visible on both 

 sides, instead of strongly curved, as in that species. The funicle of the an- 

 tennae consists of two parts; the first joint rather large, as usual, and about 

 as wide as long; the remainder is narrow at base, gradually becoming 

 broader, and forming a slem to the club; this stem is divided by three 

 transverse sutures which are frequently very indistinct, and I consider 

 their number as having little value. 



The front tibiie are c )mpressed. with one acute outer edge, but no flat- 

 tened space as in Monarthrum; this edge is very feebly serrate; the joints 

 1-3 of the tarsi are subequal and rather stout, the fourth is small; fifth about 

 as long as the others united; claws large, divergent. 



A. Club of antennse nearly smooth on the outer surface, and indistinctly 

 annulated, sparsely fringed with long hairs; upper surface pubescent, su-
