CLEONINI. 159 



Canada to Texas ; Colorado. Shorter and stouter than our other species, 

 and variable in appearance, according as the pubescence is well preserved 

 or abraded. There is also some variation in the number and depth of the 

 large punctures of the prothorax. The antennsB in ^ are about one-fourth 

 from the tip of the beak ; in 9 about one-third. The prothorax is wider 

 than long, strongly narrowed in front, rounded on the sides, feebly con- 

 stricted at tip ; the dorsal excavation is not deep except at the base. 



15. L. perforatus, n. sp. 



Elongate, black, thinly clothed with gray pubescence. Beak as long as 

 the prothorax, finely punctured ; head very coarsely punctured. Protho- 

 rax longer than wide, narrowed in front, feebly rounded on the sides, 

 which are more thickly pubescent, very deeply and coarsely punctured, 

 interspaces densely punctulate, basal excavation small. Elytra a little 

 wider than the prothorax, scutellar impression wide not deep, intrahumeral 

 impressions deep ; striae composed of subquadrate not distant punctures, 

 tips separately acuminate, but not prolonged ; the inner and outer inter- 

 spaces more densely pubescent, but not very obviously so. 



(^. Beak stouter, densely punctured, more coarsely on the sides, more 

 finely towards the tip ; antennae one-third from the tip. 



9. Beak more slender, shining, sparsely and finely punctiired, sides 

 sparsely and less finely punctured. Antennae inserted about the middle of 

 the beak. 



California, Fort Tejon. The elytral strise are alternately a little nearer.

 14 ; ed. Lee. i, 276. 



One 9 specimen, Kentucky. A small species easily known by the sides 

 of the pi'othorax nearly parallel, much rounded and constricted near the 

 tip ; the dorsal excavation is small and basal; the punctures very large and 

 deep, though sparse. The sides of the prothoi'ax and elytra are more 

 densely pubescent ; the tips of the elytra are rounded ; the antennas are 

 inserted at the middle of the beak, which is sparsely punctulate, with a 

 few punctures intermixed at the base and sides. Length 7 mm ; .27 inch 



17. L. placidus, n. sp. 



Black, somewhat shining, thinly pubescent, sides of prothorax and sub 

 marginal broad vitta of elytra whitish pubescent. Beak rather stout, as 

 long as the prothorax, finely not densely punctured, with a few larger punc- 

 tures towards the base and on the sides ; antennae inserted at the middle of 

 the beak. Prothorax a little longer than wide, gradually narrowed from 

 the base, feebly rounded on the sides, not constricted at tip, finely punc- 

 tured, with scattered not remote, moderately large but not very deep punc- 

 tures, disc channelled, with a small basal impression. Elytra a little wider 

 than the prothorax, conjointly rounded at tip, basal impressions shallow; 

 striae composed of large rather distant punctures. Length 10 mm. ; .40 inch. 



Two 9> Colorado. A very distinct species of moderately elongate form.
