340 THE CANADIAN ENTOMOLOGIST. 



the seventh interval is not abruptly interrupted, the ventral segments are 

 not sparsely and finely punctured, and the beak is rather slender, and not 

 "exceedingly stout " as in that species. 



Coiiotrachelus Arizofiicus, new species. — In form and general 

 coloration resembling leucopJueatus, but thorax not as coarsely punctured, 

 and without crests in front, the costae on elytra feeble and nearly obsolete 

 on the disk, but prominent at apex, the upper surface with short semi-erect 

 setae. Head densely punctate, clothed with ochreous hairs, eyes separated 

 by the width of the beak, the latter feebly curved and moderately stout, 

 strongly convex at base, tricarinate, the intervals between the carinse. 

 rugose, at apex moderately coarsely punctate; antennse inserted at slightly 

 less than apical third. Thorax broader than long ; sides nearly straight 

 and parallel to a little before middle, then strongly narrowing to apex and 

 feebly constricted ; surface coarsely punctate, very sparsely clothed on the 

 disk with ochreOus and at sides with white hairs, which are inclined 

 forward. Elytra very feebly sinuate below the humeri, the latter rounded; 

 surface with rows of large, closely-placed punctures ; alternate intervals 

 feebly elevated on the disk and at sides ; at apex the third has two 

 moderately prominent crests, and the fifth and seventh are distinctly 

 elevated; colour brown, with pale brown, white and yellow hairs, the latter 

 more condensed on the second and third interval at base, the white 

 forming a broad, irregular, oblique fascia from the humerus to nearly the 

 middle of suture, the rest more irregularly and sparsely intermixed with 

 white ; surface with short, semi-erect pale set?e. Body beneath sparsely 

 clothed with pale hairs, and very coarsely punctate ; mesosternum nearly 

 flat, not impressed in front ; legs sparsely i)ubescent, slightly denser on 

 the broadest part of hind femora, femora with one moderate tooth and one 

 feeble tubercle, claws with a small tooth. Length, 4 mm. 

 Arizona, one specimen in collection Dietz. 



This species is to be placed near nivosiis in I.)r. Leconte's table, 

 from which the closely punctured and very sparsely pubescent thorax, the 

 slightly longer beak, the distinct elytral crests and the pale sette on elytra 

 will separate it. 



Conotrachelus ecarinattis, new species. — Brown, elytra clothed very 

 sparsely with pale and ochreous hairs, the latter forming an indistinct band 

 behind middle, costre almost obliterated, thorax without carina. Head 

 closely punctate, and with short yellowish- while hairs, feebly transversely
