disk convex, finely subrugulose, densely punctate, with a deeply im- 

 pressed median line, densely squamose and with prominent suberect 

 setiform scales. Scutellum minute, triangular, evident. Elytra oblong- 

 oval, abruptly declivous, and slightly inflexed at apex, one-half longer 

 than wide, two-thirds wider than the prothorax; sides feebly arcuate; 

 humeri narrowly rounded, slightly prominent; base broadly emarginate; 

 disk convex, coarsely and rather strongly striate, striae nearly as wide 

 as the intervals, equal, having rows of moderate rather deep punctures 

 which are separated by about three times their own widths, and each 

 closed by a broad whitish scale; intervals convex, each with a single 

 prominent line of long, erect setiform scales. Legs rather robust; an- 

 terior tibiae finely denticulate within; cotyloid surfaces oblique; terminal 

 spur of posterior small but distinct. First ventral segment more con- 

 vex; suture arcuate in middle three-fourths; second segment much lon- 

 ger than the next two together. Length 6.5 mm. 



Nevada (Washoe Co.). 



The mentum almost entirely fills the gular opening, entirely 

 covering the maxillae; it is moderate in size, as wide as long, 

 subquadrate with the angles rounded, concave behind, not pe- 

 dunculate. The mandibular scar is rather large and prominent, 

 subtriangular. The apical cavernous portions of the antennal 

 scrobes are quite as open when viewed vertically as laterally, in 

 this respect seeming to form a transition toward Phyxelis. 



This species, which differs from cequalis Horn in color and in 

 its deeper median thoracic line and elytral striae, was found in 

 abundance in the bed of the Truckee River at Reno, under stones 

 in very early spring. 



The setiform scales of the upper surface are very prominent, 

 and of a bright brownish-yellow color. 



]fIlL.OI>£RE^ n. gen. (Ophryastini). 



This name is proposed for a very singular species possessing 

 the following assemblage of characters : — 



Beak slightly longer and narrower than the head, very feebly nar- 

 rowed toward apex ; alse very feebly dilated ; surface of head and beak 

 continuously convex, without trace of transverse impression. Eyes 

 rather small, slightly convex, coarsely granulated, oval, slightly wider 

 than long. Antennae rather slender, subapical ; scape slender at base, 

 abruptly clavate, attaining the middle of the eyes ; funicle slender, 

 seven-jointed, basal joint as long as the next two combined, outer 

 joints shorter, moniliform, seventh slightly wider than long, oval, rather 

 close to the club ; the latter elongate, rather narrow, pointed, finely
