678 Coleopterological Notices, IV. 



as long as the prothorax, compressed, smooth, polished, punctured 

 and squamose near the base, strongly, abruptly arcuate at base but 

 nearly straight and gradually feebly flattened thence to the apex ; 

 antennae inserted near the middle, the basal joint of the funicle as 

 long as the next four. Prothorax slightly wider than long, swollen 

 at the sides anteriorly and wider at apical third than at base, the 

 sides convergent and feebly constricted thence to the apex, the latter 

 barely two-thirds as wide as the base ; disk rather closely, strongly, 

 unevenly punctured, with a narrow impunctate median line. Scu- 

 tellum very small, quadrate, glabrous. Elytra quite distinctly wider 

 than the base of the prothorax, feebly subinflated behind the middle, 

 distinctly more than twice as long as wide, the humeral callus 

 slightly prominent ; striae fine, deep and abrupt ; intervals flat. 

 Prosternum broadly, deeply impressed along the middle, the mar- 

 gins of the impression not abruptly defined ; transverse constriction 

 moderately distinct ; anterior coxae separated by one-fifth of their 

 own width, the intermediate by slightly less than their width. 

 Length 3.1-3.3 mm.; width 1.0-1.1 mm. 



Nebraska. Distinct from filiforme in its larger size, more robust 

 outline, etytra wider than the prothorax, longer beak and many 

 other characters. 



4 Barilepton falciger n. sp. — Cylindrical, convex, black through- 

 out, shining and with a feeble violaceo-metallic lustre, densely clothed on the 

 elytra with rather large, pale scales, which are sparse and narrower on the 

 pronotum, also dense toward the sides of the sterna and last three ventral 

 segments. Head rather finely, closely punctate, almost impunctate and 

 broadly excavated beneath ; basal constriction obsolete, the outline straight in 

 profile ; beak short, robust, sickle-shaped, very strongly bent at basal third 

 and strongly compressed, slightly flattened toward apex, smooth, polished, 

 punctured toward base, not quite as long as the prothorax, the antennae 

 inserted just beyond the middle and near the upper margin, the scrobes rap- 

 idly oblique along the flattened flanks, the basal joint of the funicle longer 

 than the next four, obconical, the second much narrower, cylindrical, not 

 quite as long as the next two, outer joints more robust ; club moderate, 

 nearly as long as the preceding six joints. Prothorax but slightly wider than 

 long, the sides feebly divergent and nearly straight to apical third, then 

 rounded and convergent to the apex, the constriction obsolete ; apex three- 

 fourths as wide as the base ; disk not very coarsely, somewhat unevenly punc- 

 tate, the punctures well separated ; narrow impunctate line distinct. Scutel- 

 lum very small, nearly glabrous. Elytra not at all wider than the disk of the 

 prothorax, but, at base, just visibly wider than the base of the latter, dis- 

 tinctly more than twice as long as wide, parallel, parabolic in apical third ; 

 humeri not prominent ; disk with a more prominent humeral condensation
