AMERICAN COLEOl'TERA. 315 



llicirax densely cribratoly puncturcil, prostornal sutures not canaliculate in 

 front. Pectus and abdomen coarsely punctured and sparsely pubescent. 

 Length .^i) inch : 9 mm. 



Abundantly different from our species of Lnnnnius, by the thoracic 

 sculpture as well as by its slender form, resembling rather some of our 

 elongate Jlehiiiofns. 



One specimen from California, without special designation of locality. 



L. nitidulus, n. sp. — Black, shining with a tinge of aeneous, surface sparscly 

 olothed with cinereous pubescence. Head coarsely punctured, vertex with 

 slight impression, frontal margin truncate and at middle slightly emarginato. 

 Antennte black, third joint longer than second and equal to fourth. Thorax 

 longer than broad, sides feebly rounded, gradually narrowing in front, and 

 near front angles strongly rounded, and near base slightly sinuate, hind angles 

 sub-acute and carinate, disc convex shining not coarsely nor densely but 

 equally punctured. Elytra as wide as thorax feebly narrowing behind, sur- 

 face moderately convex, finely striate, intervals flat densely and equally punc- 

 tulate. Body beneath entirely black, sparsely punctulate and pilose. Proster- 

 nal sutures in front distinctly canaliculate. Length .24 — .28 inch; 6 — 7 

 mm. 



Allied to L. iii'tiJlcoUlif, Lee. (Ann. Mag. Nat. Hist. Dec. 1869), 

 differs as follows ; thorax broader, sides more strongly rounded in 

 front, disc less bronzed and more densely and coarsely punctured; the 

 elytral intervals are densely and evenly punctulate, those o? lih'idicolfis, 

 being biseriately punctulate and on the alternate intervals only, cspes- 

 cially toward the basal region. The margin of front of nitidulus, is 

 truncate and even slightly emarginate at middle, that of nitidicoHs, 

 being rounded. The third joint of anteiinfe of the former species is 

 as long as the fourth and in the latter decidedly shorter, and while JuVt- 

 <iidns has the prosternal sutures anteriorly distinctly canaliculate, 

 those of nitidico/iis, are not so. 



Several specimens were collected by Mr. Gabb, in Southern 

 Oregon. 



According to the tables of Candcze, those two species arc allied 

 to parvulus. 



I. infuscatus, Motsch. Bull. Mosc. 1859, IV, p. STl, and L. occidentalis, Cand. 

 Monog. Ill, p. 411, are not synonymous as placed by Leconte in the List p. 47. 



Specimens of the latter species have been sent me by Mr. Edwards, 

 which differ in many important particulars from the type of infus- 

 cafux, sent to Dr. Leconte, by Motschulsky. In color both agree in 

 having ferruginous red elytra, occidentalis, being the brighter in color 

 that of iii/'iiicatHx, inclining to brownish, usually slightly bronzed; 

 the thorax of iu/iiscatm, is shining tinged with reneous and not 

 dcn.sely punctured; occidentalis is black without lustre and very
