18- THE CANADIAN ENTOMOLOGIST 



Holotype, male, and allotype, female, in my own collection. Paratypes in 

 the collection of the California Academy of Sciences. 



Forty-eight specimens studied. A moderate series was collected at Tonopah 

 Nevada, by my mother-in-law, Mrs. E. C. Peek; a similar series was taken at 

 Goldfield, Nevada, by Mr. F. W. Nunenmacher. The species was collected 

 June 29th, 1907, from the blossoms of an undetermined plant. 



A large species related to ampins Casey and ohlongiis Casey by the horizontal 

 epipleura, which extends to the extreme apex of the elytra. Grandicollis ap- 

 pears sufficiently distinct and inhabits a different region from Casey's species. 



Eudasytes hirsutus, new species. 



Form oblong, about two and a third times longer than wide, moderately 

 convex. Colour deep black and shining; femora nigro-piceous, tibiae rufo- 

 piceous, tarsi almost rufous; antennae rufous or rufo-piceous toward base and 

 piceous distally; mouth-parts more or less rufous. Pubescence brownish-gray 

 and sparse; subrecumbent hairs about a third as long as the long flying hairs 

 which are bristling throughout, sparse and equally distributed over the elytra 

 and pronotum ; marginal fimbrice of the pronotum and elytra long, blackish and 

 not close set. Head moderately large, front scarcely convex, feebly bi-impressed, 

 with a small, smooth feebly convex area near the apical margin; punctures small, 

 irregular and sparse. Antennae rather stout, subserrate anteriorly, angles blunt 

 and rounded, last three joints noticeably thick. Eyes finely setigerous, setee 

 short. Pronotum transversely oblong, about a fourth wider than long; sides, 

 subparallel, slightly convergent, almost straight, feebly arcuate, anteriorly 

 broadly and very feebly sinuate posteriorly, margin rather thick; apex broadly 

 emarginate, subtruncate in middle third, not at all beaded; apical angles rather 

 broad, anteriorly prominent and rather more than narrowly rounded; base 

 arcuate in middle third, broadly and feebly sinuate laterally, margined and with 

 a submarginal groove ; basal angles rectangular to almost less than a right angle 

 and somewhat prominent laterally ; disk broadly and less than moderately convex, 

 most so centrally, slightly impressed at the apical and basal angles, puncture 

 rather coarse, sparse, denser at the angles, smaller in the central area, interstitial 

 surface shining and glabrous. Elytra rather less than twice as long as wide, 

 punctures sparse, not sharply defined, surface more ot less rugulose; margin 

 slightly reflexed, rather narrow and with a distinct but narrow gutter; sutural 

 angles rounded. Epipleura horizontal, moderately wide, inflexed at apex at 

 the beginning of the apical curve, inner margin evanescent without convergence 

 to the outer margin; gradually widened from the humeral angles. Abdomen 

 finely punctured, pubescence denser and recumbent. 



Male. — Comparatively less broad. Basal pronotal angles more prominent 

 laterally, tips not rounded. Fifth ventral abdominal segment truncate, some- 

 times slightly impressed at middle of the apex so as to appear feebly sinuate. 



Female. — Broader and stouter. Basal angles of the pronotum less prominent 

 and slightly blunt. 



Length 2.5-3.5 mm.; width 1.0-1.6 mm. 



Type locality. — Tonopah, Nevada. 



Holotype, male, and allotype, female, in my own collection; paratypes in
