CLEONINI. 151 



tato-striate, with two cinereous vittse occupying the third, fourth, and fifth, 

 and three outer interspaces, apices separately rounded, and slightly acumi- 

 nate. Hind tarsi with the third joint not broader than the second, bilobed, 

 not spongy beneath. Length 8.75-11.8 mm. ; .35-. 46 inch. 



7. O. canescens, n. sp. 



Black, clothed with extremely fine and short, almost pruinose pubescence. 

 Beak very stout, slightly thickened at tip, shorter than the prothorax, 

 coarsely punctured, strongly carinate; carina abbreviated one-fourth from 

 the tip, which is not emarginate, ending behind in a frontal puncture. 

 Prothorax a little wider than long, sides nearly parallel, suddenly rounded 

 and narrowed at the tip, which is feebly impressed at the sides, base broadly 

 bisinuate, middle lobe feebly angulated, basal angles obtuse and rounded, 

 disc densely punctulate, sparsely and very coarsely punctured, basal con- 

 cavity deep, extending nearly to the middle. Elytra with rounded .humeri, 

 a little wider than the prothorax, sides parallel, then obliquely narrowed, 

 tip obtusely rounded, semicircularly deeply impressed around the scutel- 

 luin, which is small and deeply placed, front end of suture elevated, form- 

 ing a small cusp ; striaB composed of large distant punctures, interspaces 

 flat, scarcely wider than the space between the individual punctures of the 

 rows, slightly mottled with dots of denser whitish pubescence, and spots 

 of a darker color. Beneath more coarsely and densely gray-pubescent, 

 with large black punctures. Hind tarsi longer than the others, first joint 

 longer than the second, third broader, bilobed, with the lobes spongy be- 

 neath, broadly grooved at the middle. Length 10 mm. ; .40 inch. 



Colorado. Four specimens given me by Mr. Ulke. The beak is thicker 

 than in the neighboring species, and it is otherwise easily recognized. 



8. C. jpuberulus, n. sp. 



Black, clothed with coarse pale gray pubescence. Beak coarsely punc 

 tured, rather stout, not dilated at tip, sides parallel, upper surface not very 

 convex, scarcely carinate, front feebly concave transversely. Prothorax 

 not longer than wide at base, gradually narrowed in front, feebly con. 

 stricted at the tip, base broadly bisinuate, middle lobe broadly rounded, 

 disc with a few large scattered punctures, black, with the sides and two 

 broad converging vittae, which almost meet at the tip, gray ; basal excava- 

 tion very large and deep, extending beyond the middle. Elytra wider than 

 the prothorax, broadly impressed around the scutellum, and flattened 

 towards the humeri, which are rounded, sides parallel, then obliquely nar- 

 rowed, tips obtusely rounded, sub-acuminate ; striae composed of large 

 close set punctures, interspaces slightly convex, first, second, and seventh 

 darker, and mottled with a few small spots. Beneath with large scattered 

 black punctures ; hind tarsi with first joint not longer than second, third 

 joint slightly wider, bilobed; lobes spongy beneath. Length 8-9.5 mm. ;
