fascia which extends forward along the suture becoming broader at base, 

 black ; or the elytra may be defined as black, each with a somewhat oblique 

 gradually widening stripe extending from the humerus to the middle, and 

 a subapical lunate spot, rufotestaceous. Recumbent pubescence rather 

 dense, and bristling throughout— more especially on the elytra — with 

 numerous long semi-erect hairs ; punctuation fine, somewhat closer and 

 more distinct on the elytra than elsewhere. Head and antennae nearly 

 as in nuperus, the tempora, however, a little less strongly oblique than in 

 the latter. Pronotal horn two fifths as wide as the prothorax, distinctly 

 margined, the margin dentellate at sides posteriorly; crest with feebly 

 reflexed non-dentellate margin. Sutural angles of the elytra (c^) sepa- 

 rately rounded and just perceptibly produced, with a feeble external sinua- 

 tion. Body beneath darker rufous, the abdomen piceous, the last segment 

 somewhat paler. 



Length 4 mm.; width 1.2 mm. 



The unique type is a male, having the last ventral segment 

 squarely truncate at apex and broadly transversely impressed 

 throughout its width; it was taken at Silver City, New Mexico, 

 by Mr. J. B. Wallis, from whom I received it. 



As already observed, this species is nearly identical with 

 nuperus in elytral markings and by Casey's table would be asso- 

 ciated with it. The latter species however entirely lacks the erect 

 hairs of the upper surface, and the form of the elytral apices, and 

 the impression of the last ventral in the male are different. 



Notoxus brevicornis n. sp. Rufous, head, prothorax above (except the 

 horn) and abdomen more or less suffused with piceous ; elytra black with 

 two paler fasciae, one before the middle, narrowest at suture, gradually 

 widened, and produced anteriorly at sides so as to include the humeri ; 

 the other behind the middle, narrower, biarcuate. Pubescence moderately 

 dense, intermixed on the elytra with short semi-erect hairs which are not 

 very conspicuous except in profile; punctuation moderate, integuments 

 somewhat shining. Antennae about as long as the head and prothorax, 

 very feebly incrassate apically, the tenth joint scarcely longer than wide. 

 Eyes rather small but evidently longer than the tempora. Prothorax about 

 as long as wide; horn rather stout, not constricted at base, fully one half 

 longer than wide, more than one third the width of the prothorax, margin 

 not dentellate, crest well developed, with nondentellate margin. Elytra 

 four fifths longer than wide, obviously widened postmedially, apex obtusely 

 rounded, the sutural notch very narrow, the angles only slightly rounded. 

 Body beneath and legs as usual, the last ventral ($) with the tip rounded. 



Length 3 mm. ; width i mm.
