THE CANADIAN ENTOMOLOGIST 185 



Orthotomicus ornatus, n. sp. 



This is a small elongate species, allied to spams [balsameus) 

 Lee, and also to ccelatus Eichh. 



Description of the male — Length, 2.3 mm. The head has the 

 front convex, closely, rather coarsely granulate, with the median 

 carina nearly obsolete, the hairs long but sparse; the antennal 

 club about as wide as long, thickened basally, the apical half 

 strongly obliquely truncate, the first suture recurved, with the 

 apical segments almost completely telescoped, showing only one 

 suture at the apex, on the upper surface. 



The pronotum is distinctly longer than wide, with the sides 

 straight to well beyond the middle, then narrowed to the broadly 

 rounded front margin; coarsely very sparsely asperate and finely 

 granulate, moderately punctured behind, closely on the sides, 

 rather sparsely on the disc, with a smooth medium space becoming 

 narrow and slightly carinatt towards the summit. 



The elytra have the sides stiaight and parallel for four-fifths 

 the length; then semicircularly rounded behind as viewed from 

 above; the striae narrow, straight, regular, and slightly impressed; 

 the sutural strise slightly wider and more strongly impressed on 

 the disc, still more strongly behind, but not widened before the 

 declivity; the strial punctures rather large except towards the 

 base, regular, quadrate, and very closely placed; larger and closer 

 behind; the interspaces nearly flat, those of the disc wider than the 

 striee in front and narrower towards the declivity, uniseriately 

 punctured, the punctures rather numerous, about 12 on the discal 

 interspaces between the base and the top of the declivity, the 

 punctures very small in front becoming as large and close as those 

 of the striae and granulate near the declivity. The declivity is 

 vertical, moderately concave, somewhat less deeply than the male 

 of sparsus; densely, coarsely punctured and hairy; with three 

 acute teeth on each elytron, the first tooth minute, on the second 

 interspace; the second extremely coarse, stout at the base, acute, 

 incurved, on the third and fourth interspaces, much clcser to the 

 first tooth than to the third; the third smaller, slender, straight 

 and acute, on the sixth and seventh interspaces; the second and 

 third on the margin of the declivity, which is completed laterally
