Ips borealis, n. sp. — Length, 3^-33/2 mm.; width, i^ mm. Sides 

 parallel, smaller and more slender than pini. Head and prothorax black, 

 elytra dark brown to black, legs and antennae lighter. Prothorax three- 

 fourths as long as the elytra. 



Head rather prominent, globular, beak rather distinct with the angles 

 square. Vertex and ffont convex ; whole upper part of head remarkably 

 smooth and shining. Front with a faint transverse impression extending 

 between the eyes. In one sex the front is nearly as smooth as the vertex, 

 very finely punctured with extremely minute hairs ; in the other sex the 

 front is densely, minutely granulate-punctate, and hairy below. These 

 hairs from the front are brownish, slender, and erect. In both sexes the 

 epistomal margin is densely fringed with yellowish or orange hairs ; and 

 close to the margin, and parallel to it, is a row^ of close-set, short tubercles. 

 The eyes are elongate, broadly rounded above, and faintly emarginate in 

 front. The genee are sparsely punctured, aciculate, with large punctures 

 below. The club is large, short-oval, with the first two sutures distinctly 

 bisinuate. * 



The pronotum is longer than wide, hardly wider than the elytra ; the 

 sides are nearly parallel forward for three-fourths the length, then rapidly 

 narrowed ; the caudal margin is obtusely angled at the middle, with the 

 hind angles rounded. The anterior half is rather coarsely tuberculate, as 

 usual ; the posterior half is shining, coarsely and sparsely punctured with 

 the punctures slightly tubercul.\te on the sides, and a wide, smooth, shining, 

 median space. 



The eiytral striae are but faintly impressed, except the sutural strice 

 which are wide and deep ; the strial punctures are medium in size, not 

 close, and not regularly spaced ; those of the sutural striae are larger and 

 closer. The intervals are wide and flat, and uniseriately punctured 

 throughout their length. The punctures of the first two interspaces are 

 closer and strongly granulate ; those of the remaining interspaces are 

 sparse on the disc, closer and granulate near the margin of the declivity ;
