more distant. Elytra broadly emarginate at base, one-fourth wider than 

 the prothorax, humeri rounded; stris strongly punctured, interspaces 

 slightly convex, conjointly rounded at tip in both sexes. Length 8 mm. ; 

 .33 inch. 



(^. Last ventral not impressed. 



9- " " with a broad, shallow impression. 



One pair of partially abraded specimens : Georgia. Easily known by the 

 stouter and more deeply sculptured beak, and stouter antennae; otherwise 

 it resembles L. nebulosus in form. 



12. L. nebulosus, n. sp. 



Elongate, blackish, clothed with scales, mottled brown and dark, on the 

 head with a metallic lustre. Beak feebly carinate and sulcate as usual. 

 Prothorax longer than wide, sides feebly rounded for two-thirds the length, 

 then more rounded to the tip ; scales small, a bifurcated lateral vitta, and 

 an interrupted dorsal line paler ; punctures dense and deep. Elytra about 

 one-fourth wider than the prothorax, strongly emarginate at base, humeri 

 oblique, slightly rounded ; striae strongly punctured, interspaces wide and 

 flat. Thighs with a pale band. Length 9.5 mm. ; .375 inch. 



9. Last ventral slightly impressed ; elytra conjointly rounded at tip. 



One 9> Missouri. Easily recognized by the elongate form and mottled 

 color. 



13. L. frontalis, n. sp. 



Blackish, less elongated, covered with rounded scales, which are no 

 larger on the prothorax; these scales are dirty brown on the elytra, and with 

 a metallic lustre on the head and prothorax. Beak finely carinate, lateral 

 grooves almost obsolete, frontal fovea deep. Prothorax verj^ little longer 

 than wide, broadly rounded on the sides, transversely impressed near the tip; 

 lateral stripes and dorsal line indistinctly paler, punctures dense, of two 

 sizes, the larger more distant. Elytra one-third wider than the prothorax, 

 broadly emarginate at base, humeri rounded; striae strongly punctured, 

 interspaces wide, nearly flat; tip conjointly rounded in both sexes. Length 

 5.7-10 mm.; .23-. 40 inch. 



(J*. Last ventral not impressed; anal segment slightly prominent. 

 9 . Last ventral with three shallow impressions. 



Michigan, New York, Georgia, Texas. Stouter than L. nebulosus, and 

 easily recognized by the above characters. The setae of the elytra are more 

 obvious than usual. 



14. L. oregonensis Lee, Pac. R. R. Expl. and Surv. Ent 55. 



One abraded 9 from Oregon. The last ventral segment is not at all im- 

 pressed. The beak is feebly carinate, and obsoletel}' sulcate, the fnjntal 

 fovea not deep. The prothorax is a little wider than long, much rounded 

 on the sides, and feebly channeled, the sculpture is peculiar, consisting of 

 small granules, separated by deep rugosities, and mixed with large, scat- 

 tered punctures; on each granule is a small puncture; the few scales which 

 remain are small, and indicate three paler stripes. The elytra are one-third
