middle, sparsely and coarsely pubescent, the transverse tomentose line at the 

 base very vridely interrupted; liorn small, strongly and abruptly- crested, 

 slightly longer than wide, not constricted, evenly rounded at tip, botli horn 

 and crest surrounded by an acutely elevated and non-dentellate margin. 

 Elytra elongate, twice as long as wide, very appreciably dilated at apical third 

 and twice as wide as the prothorax, gradually narrowed and somewhat acutely 

 parabolic in apical third, the sutural angle rounded but not at all truncate; 

 intra-humeral imijression distinct, the 'post-scutellar very strong; disk mi- 

 nutel}^, sparsely punctate, finely dusky-pubescent, except in the transverse 

 fasciic, where the vestiture is coarser and cinereous; erect setce long but rather 

 fine and sparse. Abdomen strongly shining, the minute punctures feeble. Lega 

 moderate, the hind femora dusky. Length 2.7 mm. ; width 0.85 mm. 



Arizona (near the Canon of the Colorado). 



This is a well marked species, to be readily known by its long, 

 polished, sparsely and minntely punctate elj^tra, which are nar- 

 rowed obliquely behind from slightly before apical third, also by 

 its small prothorax with an unusually small corneous process, 

 long antenna and other characters. 



A single specimen, probably male, was recently taken by Dr. 

 T. Mitchell Prudden, of New York, and kindly presented to me 

 together with a number of other interesting species. 



]V. spatulifer, — Somewhat narrow, parallel, polished throughout, pi- 

 ceous-brown, the antennje paler and the elytra black, the latter with the 

 basal margin and a transverse fascia at basal third pale, the latter clothed 

 with coarser, closer and more cinereous pubescence, a transverse band occupy- 

 ing apical fourth also similarly pubescent, the vestiture elsewhere fine, dark 

 in color and very sparse; erect seta; sparse, more distinct in the cinereous 

 areas. Head but slightly smaller than the prothorax, convex, polished, very 

 remotel}' pubescent, the eyes small, much shorter than the tempora; antenna? 

 one-half as long as the body, somewhat thick, just visibly and verj' gradually 

 incrassate, slightly infuscate toward apex, the tenth joint distinctly elongate. 

 Prothorax globular, not wider than long, polished, finely and sparsely punc- 

 tate throughout, the basal tomentose line scarcely at all interrupted; horn 

 well developed, circularly' rounded at apex, not dentellate, feebly but rather 

 abruptly constricted at the middle and thence parallel to the base, narrower 

 and scarcely at all constricted in the male; crest abrupt, moderateh^ elevated, 

 acutely outlined along the sides but indefinitely so anteriorly; surface of the 

 horn concave and strongly scul])tured. Ehjtra t\\ice as long as wide and paral- 

 lel in the male, shorter and slightly inflated in the female, narrowly and ob- 

 liquely truncate near the suture in the former, broadly and squarely truncate 

 throughout the width in the latter sex, scarcely more than one-half wider 

 than the prothorax, rather sparsely and somewhat strongly Itut not verj' 

 coarsely punctate, without basal impressions of any kind, even post-scutellar. 

 Under surface rather coarsely and sparsely pubescent. Length 2.G-;2.8 mm.; 

 width 0.75-0.85 mm.
