to the acute apical margin; the declivital margin, viewed from the 

 side, straight and vertical from the base of the third tooth to the 

 base of the acute apical margin; the acute apical margin elongated 

 towards the tip so that the apex of the declivity becomes sub- 

 acuminate, and the edge with two deep emarginations on each 

 side; the depth of the declivity closely punctured and dull from 

 numerous minute wrinklings of the chitin, the punctures bearing 

 short, slender hairs throughout. The pubescence is long, light and 

 prominent about the side and margin of the declivity. 



The A-enter is densely punctured and clothed with long hairs. 



This species was obtained through the kindness of Mr.W. 

 Knaus. The type bears the labels, Cloudcroft, 9000 f., N. M., 

 W. Knaus, 8-8-03, 197. 



Ips perroti, n. sp. — Description of the type, a male: A. 

 slender species, dark reddish-l^rown in all my specimens; length 

 4 mm., width 13^ mm., relative proportions, length of pronotum 29, 

 length of elytra 46 , width of pronotum behind 27, width of elytra 

 in front 26, width of elytra behind 28. 



The head has the front convex, somewhat flattened in front, 

 rather closely punctured, more coarsely and roughly towards the 

 eyes, sparsely granulate on the disc, more densely towards the 

 epistoma, with a short, blunt median tubercle on the epistoma, 

 and a row of smaller blunt tubercles along the epistomal margin; 

 the disc rather sparsely clothed with slender hairs, and the epistoma 

 densely fringed as usual; the gena; moderately closely and deeply 

 punctured; the eyes with a very broad, shallow emargination in 

 front; the antennal club with the first two sutures slightly bisinuate.. 

 at the middle, strongly bent distad at the sides. 



The pronotum is slightly longer than the width, with the caudal 

 margin strongly rounded; the sides nearly straight and parallel 

 for two-thirds the length, rather strongly narrowed on the distal 

 third and rounded in front; rather densely hairy on the sides and 

 in front, glabrous on the disc; irregularly, not very coarsely asperate 

 in front; smooth and shining behind and finely sparsely punctured,
