EROTYLID^E 153 



Color ferruginous, the elytra with a broad common black vitta from base 

 to apex and a narrower one, obsolescent apically, at the sides, the 

 under surface piceous-black, the abdomen in part nubilously paler, 

 the legs brown. Head fully two-thirds as wide as the prothorax, 

 finely, moderately closely punctate, the eyes somewhat prominent; 

 antennal club oblong, longer than wide, its last two joints shorter 

 and even more transverse than the first; prothorax four-fifths wider 

 than long, the sides straight and feebly converging from base to 

 about apical fifth, where they become rounded and more convergent; 

 side margins rather thick; punctures deep, not very coarse, somewhat 

 close-set, evenly distributed and conspicuous; base distinctly lobed 

 medially; scutellum transversely oval, minutely punctulate; elytra 

 elongate-oval, nearly twice as long as wide, distinctly wider than the 

 prothorax, the base exactly equal to the thoracic base; sides broadly 

 arcuate, rather more prominently so just behind basal fourth, the 

 combined apices rather broadly parabolic; punctures not coarse but 

 distinct, arranged in a few distinct even series, which disappear 

 apically, the general surface irregularly, not closely and rather less 

 strongly punctate; under surface finely, deeply and closely punctate. 

 Length 3.0 mm.; width 1.25 mm. Nevada vittata n. sp. 



Coloration diversified but never vittiform on the elytra 2

Elytral punctures minute and without trace of serial arrangement at any 

 part ... 7 



3 Base of the prothorax broadly and feebly lobed medially; head larger, 

 very much wider than an elytron. Body rather abbreviated, convex, 

 polished, very pale and uniform brownish-flavate throughout above 

 and beneath in the type, the hairs extremely short and decumbent, 

 scarcely observable; head fully three-fourths as wide as the prothorax, 

 finely, strongly and closely punctate, the eyes rather small, moder- 

 ately prominent; antennal club broad, oblong-oval, its last joint 

 semicircular, longer than the preceding; prothorax relatively large, 

 fully as wide as the elytra, two-thirds wider than long, the sides 

 parallel and very evenly but moderately arcuate, the bead moderate; 

 apex and base exactly equal in width; punctures rather strong but 

 well separated throughout, the basal strides small and feeble though 

 observable; scutellum moderately transverse; elytra scarcely one-half 

 longer than wide, two and one-half times as long as the prothorax, 

 elongate-parabolic in form in about posterior two-thirds, the sides 

 becoming parallel and feebly arcuate basally and, at about basal 

 third, very slightly wider than at base; punctures rather strong, not 

 very close-set in even approximate series, obsolescent apically; 

 under surface finely, rather closely punctulate. Length 2.2 mm.; 

 width 0.9 mm. Idaho (Coeur d'Alene), James A. Leyden. 



cephalotes n. sp. 



Base of the prothorax rather abruptly and strongly lobed medially; 

 head relatively not quite so large 4 



4 Prothorax wider than any part of the elytra. Body short and 

 broader than in the other species, convex, polished, pale yellow- 

 brown in color throughout, the elytra more flavate, very nubilously
