No.B.] LE CONTE ON EOCKY MOUNTAIN COLEOPTEEA. 513 



Garland, Colo. In tlie hind angles of tlie protliorax being nearly 

 rectangular, and the pubescence very fine, this species approaches 

 (according to description) A, suturalis Maklin, from Alaska, but the 

 color of the latter is said to be black, with the margin of the elytra, the 

 front part of the suture, the antennae and the legs rufo-testaceous. 

 These differences may possibly not be specific, since the type from Lake 

 Superior and a specimen from Santa Barbara, Cal., are uniform rufo- 

 testaceous. 



Emphtlits ameeicanus. — Oblong, dark ferrugineous, scarcely per- 

 ceptibly pubescent, nearly uniformly punctured ; punctures towards the 

 tips of the elytra smaller and less impressed. Length, 2.3™°i. 



Veta Pass ; one specimen found in an ant's nest. This insect resem- 

 bles altogether the figure of the European U. gXaber (as given by DuVal, 

 Gen. Col. Europe, ii, pi. 51, f. 252), but the elytra are very distinctly 

 punctured, and not obsoletely as described by Erichson. 



Phalaceus dispae. — Bounded oval, convex, above black-brown, 

 shining, elytra with faint, ill-defined rows of fine punctures, interspaces 

 sparsely punctulate, sutural stria not impressed. Antennae, legs, and 

 under surface ferruginous. Length, 3°^"". 



Veta Pass. As large as P. peiiicillatus, and easily known by the 

 sutural stria not being impressed. 



EuTHiA LONGULA. — Elongate, rufo-testaceous, antennae and legs yel- 

 low, elytra from the first third nearly to the tip darker; pubescence sparse 

 and rather coarse. Head with two large shallow foveae. Prothorax 

 longer than wide, not narrowed in front, slightly rounded on the sides, 

 marked with a transverse impressed line near the base ; upon this line 

 are situated two large punctures each side, and a smaller one at the 

 middle. Elytra sparsely punctulate. Length, 1™™. 



Garland, Colo.; one specimen. The species are very rare, but the 

 genus is distributed widely over the continent. There are four species 

 in my collection, which may be tabulated thus : 



Elytra finely punctulate ; protliorax with a transverse line near the base 2. 



Elytra distinctly punctured colon. 



2. Protliorax a little wider than long, with a short discoidal line; hasal line not ex- 

 tending to the sides, basal foveas large; piceous, antennie and legs yellow., .scitula. 



Prothorax as long as wide, basal line strong, basal punctures 3, the middle one small, 

 the outer ones near the angles, elongate imjyressa. 



Prothorax longer than wide, basal line fine, basal punctures 5, the intermediate one 

 smaller longula. 



B. SCITULA, Maeklin, is a little larger than the other species; black, 

 with antennae and legs yellow. It is easily distinguished by the short 

 slightly impressed dorsal line. Alaska and Lake Sui^erior. 



EuTHiA niPEESSA. — Dark rufo-testaceous, shining, sparsely pubes- 

 cent. Head convex, smooth, vertex with two small fovete. Prothorax
