n6 MEMOIRS ON THE COLEOPTERA 



elytra brownish-rufous; head very finely, simply punctate through- 

 out; prothorax small, almost as long as wide, widest at the middle, 

 the sides there strongly rounded, converging and straighter 

 apically and basally, strongly crenulate throughout, the apical 

 and basal angles acutely dentate, the former slightly everted; 

 median convexity with moderate punctures, which are strongly, 

 obtusely asperate but not tubercularly granose, the broadly 

 deplanate and feebly concave sides not rugose but with rather 

 coarse, widely separated, simple punctures; elytra very regularly 

 elongate-oval, almost three-fourths longer than wide and almost 

 twice as wide as the prothorax, the ends of the basal margin 

 strongly dentate, otherwise nearly as in haruspex, except that the 

 surface is much less opaque, alutaceous and somewhat shining 

 and the inner costa, instead of being unusually evident is almost 

 completely obsolete; abdomen more shining and more strongly, 

 asperately punctate. Length (9) 18.5 mm.; width 8.8 mm. 



Utah (southwestern), Weidt ellipsipennis n. subsp. 



Form very ventricose, the anterior parts relatively much smaller than 

 in any of the preceding species, deep black, opaque, the elytra 

 more alutaceous; head finely, not densely, asperulately punctate; 

 prothorax less than half as wide as the elytra, two-fifths to one-half 

 wider than long, widest near the middle, the sides rounded and 

 finely, unevenly crenulate, the apical angles acute, feebly everted, 

 the basal obtuse, not rounded, sometimes with a minute, laterally 

 prominent point; base broadly arcuate, more truncate medially; 

 surface moderately convex, -with the granules strong and inter- 

 mingled with more minute ones medially, gradually becoming 

 narrowly explanate, densely and moderately rugose laterally; 

 elytra much inflated, evenly oval, about one-half longer than wide, 

 the sides of the base parallel for a very short distance but scarcely 

 prominent; surface rather strongly, evenly convex throughout the 

 width, finely, not densely granulate, the outer costa rather fine 

 but strong, the inner very fine and subobsolete though evident; 

 abdomen finely, closely, subgranularly punctate. Length ( 9 ) 

 18.5-19.3 mm.; width 11.5 mm. Nevada (Goldfield, Esmeralda 



Co.), Nunenmacher pantex n. sp. 



5 Body much smaller, narrower and more parallel than in any of the 

 preceding, deep black, rather shining; -head feebly impressed, finely, 

 densely, asperately punctate, the minute erect hairs indistinct; 

 prothorax small, slightly transverse, widest evidently before the 

 middle, the sides feebly crenate, rounded, gradually feebly con- 

 verging and straighter basally, becoming very feebly sinuous just 

 before the angles, which are right, not prominent, the apical obtuse, 

 slightly blunt, not at all everted, the apex unusually feebly sinuate, 

 the base broadly arcuate, feebly sinuate medially; surface very 

 broadly, evenly convex, densely granulato-tuberculate, rather 

 rapidly sloping laterally and very narrowly explanate and more 

 confusedly rugose at the sides; elytra oblong, parallel, with feebly 

 arcuate sides, three-fifths longer than wide, fully twice as wide as the
