another between the insertions of the antennre. The form and sculpture 

 are similar in the two species, but the pubescence is much more dense in 

 this one. 



5. L. caudifer, n. sp. 



Rather stout, black, densely clothed with fine short gray pubescence. 

 Beak slender, not as long as the prothorax, nearly smooth, finely 

 pubescent at base, naked at the tip. Antennae inserted about one- 

 fourth from the tip; frontal fovea elongate. Prothorax a little wider than 

 long at the base, gradually much narrowed in front and not constricted, 

 sides slightly rounded, base feebly emarginate each side, middle angle 

 prominent, acute; dorsal excavation large, triangular, channeled, surface 

 densely punctulate, with scattered shallow punctures. Elytra a little wider 

 behhid the base ; medial impression broad, not deep ; stride composed of 

 rather large distant punctures, tips prolonged, not divergent, but parallel. 

 Thighs slender. Length 9.7-14 mm.; .38-. 55 inch. 



(J^. Beak less slender, uniformly pul)escent, a little broader at tip, and 

 slightly flattened. 



9. Beak a little narrower, smooth, and naked at tip. 



Three specimens, Illinois ; found also in British Columbia. 



6. L. asper, n. sp. 



Rather stout, black, without lustre, clothed with fine gray pubescence. 

 Beak as long as the prothorax, slender, densely punctured, more finely 

 towards the tip ; antennae inserted about one-third from the tip, frontal 

 fovea distinct. Prothorax scarcely wider at base than long, gradually much, 

 narrowed in front, feebly constricted, sides slightly rounded, base 

 feebly emarginate each side, middle angle broad and rounded; surface 

 densely punctulate, with scattered large partly elevated punctures, dorsal 

 excavation large, triangular, rather deep, impressed at the middle of the 

 base. Elytra wider than the prothorax, impressions wide and tolerably 

 deep, strife composed of approximate punctures, tips separately acuminate, 

 though scarcely prolonged. Legs as in the preceding species. Length 11.3 

 mm. ; .45 inch. 



Three 9. and one (^ ; Owen's Valley, Cal., Dr. Horn. Quite distinct 

 by the rough, partly elevated punctuation of the prothorax. The beak in 

 the rf is less slender, and the antennae are one-fourth from the tip ; in the 

 9 the apical part is longer, so that they are inserted at one-third the length 

 from the tip ; it also appears very obsoletely carinate in the latter sex from 

 the front to near the insertion of the anteunse. 



7. L. Sylvius Boh., Sch. Cure, vii, 430. 



One cT Pennsylvania; coll. Horn. I refer to this species a single speci- 

 men, in which the body is black, shining, thinly clothed with fine cinereous 

 pubescence, the beak rather stout, as long as the prothorax, strongly punc- 

 tured, feebly but distinctly carinate from the frontal puncture to the inser- 

 tion of the antennse ; the prothorax punctulate and coarsely punctured, 

 with a small deep impression at the base; not longer than wide, nar-
