6 Elytra strongly shining; body stouter. Color blackish rufo-piceous, 

 the elytra rather more obscure, except the thin diaphanous and 

 strongly reflexed rufous side margins; head only slightly elongate, 

 two-thirds as wide as the prothorax, the neck abruptly formed, the 

 oblique sides behind the eyes not as long as the latter; antennae 

 moderately slender basally, thickened apically, less than half as 

 long as the body, the third joint a third longer than the fourth; 

 prothorax unusually broad, not at all longer than wide, widest at 

 apical third, the sides strongly rounded, strongly converging pos- 

 teriorly, becoming rather abruptly deeply sinuate near the base, 

 thence somewhat diverging to the right and very sharp, prominent 

 angles; base rather strongly sinuate, becoming transverse laterally, 

 fully three-fifths the maximum width and as wide as the apex, which 

 is rather deeply sinuate between the obtuse and rounded angles; sur- 

 face somewhat convex, declivous at the sides to the strongly reflexed 

 thin margins, along which the concavity is narrow and deep, becoming 

 lost basally in the large and deep basal concavities, the angles 

 appearing thereby very much reflexed; stria fine, broadly impressed, 

 conspicuous; elytra four-fifths longer than wide, evenly suboblong- 

 oval, feebly convex, barely three-fifths wider than the prothorax, 

 the humeri rather more suggested than usual, the apices obliquely, 

 strongly sinuate, the tips obtusely angulate though sharply defined; 

 striae fine, feebly impressed, indefinitely and minutely sculptured, 

 the scutellar long but feeble, the intervals feebly convex, very slightly 

 alutaceous, the third with about four small setigerous punctures; 

 legs long and slender, the hind tarsi fully as long as the tibiae; 

 first joint of the anterior with two diverging dorsal grooves, starting 

 from the middle of the base, the outer entire, the inner much ab- 

 breviated. Length (9) 13.2 mm.; width 4.5 mm. Arizona (San 



Francisco Mts.), F. H. Snow constricta n. sp. 



Elytra opaque, the body notably slender. Sierra Nevada Mountains. .7 

 7 Body, legs and antennae bright testaceous in color, the elytra dark 

 rufo-piceous, with the usual diaphanous reddish margins; anterior 

 parts and under surface shining; head of the usual subrhomboidal 

 form, three-fourths as wide as the prothorax, the eyes of the usual 

 development and convex; oblique sides behind them much longer 

 than the eyes; antennae slender, filiform, rather more than half as 

 long as the body, the third joint nearly one-half longer than the 

 fourth; prothorax only a sixth longer than wide, widest at apical 

 third, the sides rounded, converging posteriorly, becoming not 

 abruptly straight and parallel for a slight distance from the angles, 

 which are right but not at all prominent and evidently blunt or 

 rounded; base very distinctly narrower than the apex, four-sevenths 

 the maximum width, feebly sinuate, transversely rounded laterally; 

 apex feebly sinuate, with obtusely rounded angles; surface feebly 

 convex, depressed but not strongly impressed basally and with some 

 feeble punctures near the basal angles, the median stria strong, 

 feeble posteriorly; sides moderately and abruptly reflexed; elytra 

 very nearly twice as long as wide, barely visibly widest posteriorly, 

 four-fifths wider than the prothorax, the sides very oblique basally,
