OF WASHINGTON. 181 



Length n to 11.5 mm. Width 6 mm. 



Type No. 4168, U. S. N. M., nine examples from Los Angeles 

 County, California, collected by Mr. D. W. Coquillett. 



This species superficially resembles dijfficilis^ Leconte, but the 

 latter has the apex of the prosternum simple, the thorax narrowed 

 from the base with much narrower, deeply emarginate apex and 

 the posterior angles longer, slightly erected and embracing the 

 sides of the humeri. Intercalated in Dr. Horn's synoptic table, 

 E. coquilletti takes its place next after politus, Horn, which has 

 the hind angles of thorax still more obtuse, the sides rounded 

 from the base and the apex nearly semicircularly emarginate. 



Eleodes insular is , n. sp. First joint of anterior tarsi in the male with 

 a large dense brush of golden hairs at the apex beneath. Anterior femora 

 with a small acute tooth in the male, obtusely angulate in the female. 

 Elongate, black, feebly shining. Antennae robust, much longer than head 

 and thorax. Head with a smooth space on vertex, the front and epistoma 

 coarsely punctate. Thorax subquadrate, slightly narrower at apex than at 

 base ; sides finely margined, broadly and evenly rounded ; anterior angles 

 subacute, slightly prominent, posterior angles obtuse; disc moderately 

 convex, sparsely and finely punctate. Elytra at base not broader than the 

 base of thorax, gradually wider, widest at apical third, much broader in 

 the female, suddenly declivous posteriorly and slightly produced at apex; 

 disc moderately convex, slightly depressed along the suture in the female, 

 with regular distant series of fine punctures, the intervals very sparsely 

 and minutely punctulate. Legs long and slender, densely and strongly 

 submuricately punctate. Anterior femora with a distinct but obtuse tooth 

 in the male, subangulate in the female. Anterior tibiae with the spurs 

 subequal in both sexes. Tarsi with the spines ferruginous, the first joint 

 of the anterior pair in the male with a large dense brush of golden silky 

 hairs at the apex beneath. 



Length 15 to 16 mm. 



Type No. 4169, U. S. N. M. Thirty-five specimens from Sta. 

 Margarita Island, Lower California, collected by the " Albatross" 

 Expedition of iSSS. The species resembles somewhat E. quad- 

 ricollis, Eschscholtz, but the thorax is widest at base, and the 

 elytra are distinctly widest beyond the middle. All the specimens 

 are uniform in sculpture, without any tendency to muricate 

 punctuation. The unique sexual characters of the male require 

 a new subgenus between the Eleodes proper and Blapylis. 



Coelocnemis rugosa, n. sp. Elongate, deep black, feebly shining : Thorax 

 very convex, broader than long; sides not angulate, broadly rounded 

 anteriorly, sinuate posteriorly ; hind angles rectangular ; disc densely and 

 strongly punctate, rugose at the sides. Elytra very convex, oval, widest 

 beyond the middle, abruptly declivous posteriorly, the apex oval, not 

 acuminate; disc densely punctate and transversely rugose, the serial
