AMERICAN COLEOPTERA. 169 



Two European species L.parumpunctatus Gyll., and bafi/chrus Gyll., 

 are mentioned by Fauvel as occurring in North America, but I have 

 seen no specimens of them. 



3. 1,. brunnescens.— Very elongate ; head pieeous, longer than wide, sides 

 parallel, hind angles strongly rounded, upper surface sparsely but strongly 

 punctured, with a smooth medial space; under surface coarsely sparsely 

 punctured. Antennse but little longer than the head, gradually but strongly 

 thickened externally. Prothorax eastaneous, one-half longer than wide, sides 

 straight, slightly converging behind, base broadly rounded, apical margin 

 oblique each side, front angles obtuse, much rounded; disc with a broad 

 smooth dorsal stripe, limited each side by a series of well-marked punctures, 

 sides sparsely covered with similar punctures. Elytra paler red-brown sparsely 

 and distinctly punctured. Abdomen pieeous, dorsal and ventral segments 

 sparsely punctulate and pubescent. Legs ferruginous. Length 6—7 mm. 



Gilroy, Cahfornia; three specimens. 



Other specimens from San Mateo and Mojave Desert differ by the 

 punctures of the prothorax rather smaller, and the head slightly 

 wider behind. In two of them the prothorax is of a bright brownish 

 ferruginous, of the same color as the elytra. 



8. li. nijjratulus.— Pieeous black, shining, sparsely pilose; antennae and 

 feet ferruginous. Head convex, elongate-ovate, wider behind, sparselv and 

 very coarsely punctured each side, frontal grooves long and deep; under sur- 

 face sparsely and coarsely punctured. Antennse a little longer than the head. 

 Prothorax more than one-third longer than wide, narrower behind, rounded at 

 base and apex, angles much rounded, disc moderately convex, with dorsal series 

 of S— 10 punctures, sides with not more than 8—12 distant punctures. Elytra as 

 long as the prothorax, sparsely punctured with the punctures arranged some- 

 what in rows. Abdomen sparsely punctulate. Length 3.4 mm; .13 inch. 



3Iichigan, Messrs. Hubbard and Schwarz; also in Canada. 



9. Li. palli«liilus.— Testaceous shining, head and abdomen darker. Head 

 convex, elongate, slightly wider behind, coarsely and sparsely punctured each 

 side, frontal grooves long and deep. Antennse not longer than the head. Pro- 

 thorax one-third longer than wide, slightly narrowed behind, base and apex 

 rounded, dorsal rows composed of six punctures; with a curved lateral row as 

 in many Xantholinus. Elytra distantly punctured in rows. Abdomen feeblv 

 »iid sparsely punctulate. Length 2.2 mm. 



One specimen, Fort Yuma, California. Except that the last joint 

 of the maxillary palpi is small, slender, aciculate, and much shorter 

 than the turbinate third joint, this and the preceding species would 

 be placed in Xiiiif/io/ini(s^ with which they agree in the sculpture oi' 

 the head and prothorax. 



1 0. L.. scriatus. — Slender shining black, sparsely hairy, antenna and le^s 

 red-brown, elytra pale yellow, blackish in front of the middle. Head more 

 than one-half longer than wide, narrower in front, convex, base truncate, hind 

 angles broadly rounded, above and below sparsely coarsely punctured, frontal 

 grooves deej) and long; there is an undefined medial smooth space extending
