tra deeply concave, slightly hairy, bound -d by a sharp ed-n-, from the tip 

 for nearly two-thirds its lenglh; this edge termiiiates in a easp at the ante- 

 rior end; the three small d -nticles at the upper margin of the declivity are 

 much stronger than in the $. Head slightly convex, not fringed with 

 hairs, coarsely punctured, finely rugos ' and opaque near the tip.

9- Club of antennae not fringed; declivity of elytra rctuse at the side, 

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

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

 and slrongly margined. Head flat, opaque, tf unknown. 



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

 the prothorax, the antennae and legs are yellow-testaceous; the rest of th3 

 body is blackish brown. Length 2 mm. ; .08 inch.

$. 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 elytra as in -7, but 

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

 convex, sub opaque, feebly punctured.

 species.

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

 called Cryphalus, but which differ from Cryphalus tilicB 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- 

 tennaB 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 stem 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 tibiae are ompressed, 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 antenna; nearly smooth on the outer surface, and indistinctly 

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