impressed nearly throughout its width ; median impressed line broad, 

 short, with the sides parallel, becoming evanescent toward base, more 

 distinctly marked near the apex ; lateral impressions short, feeble, 

 parallel ; preocular impressions deep, short ; interocular puncture 

 small, very deep ; eyes rather convex ; surface finely, sparsely, and 

 feebly punctate toward the apex of the beak, much more densely so 

 toward base of head.' Prothorax slightly wider than long ; sides broadly 

 arcuate, convergent for a short distance near the base and a slightly 

 greater distance near the apex ; base broadly and very feebly arcuate ; 

 apex truncate, much narrower than the base ; disk convex, nearly even, 

 with a broad, deep median sulcus slightly interrupted in the middle 

 and a round, deep puncture at the middle of the length and on each 

 side of the median line ; surface finely, feebly, and not very densely 

 punctate, more densely squamose at the sides. Elytra broadly, very 

 feebly emarginate at base, oval, widest in the middle, four-fifths 

 wider than the prothorax, nearly one-half longer than wide ; sides 

 broadly, evenly arcuate ; humeri obsolete ; disk abruptly declivous 

 behind and slightly inflexed, inflexed portion of suture excessively, 

 broadly, and feebly sinuate when viewed laterally ; region of suture 

 near apical declivity slightly more prominent ; surface convex, with 

 rows of rather small, deeply impressed, widely and unevenly spaced 

 punctures ; intervals nearly flat, even. Legs and abdomen squamosa,, 

 finely and rather sparsely setose. Length 9.5 mm. 



New Mexico (Fort Wingate 1). 



The type specimen was very kindly communicated by Dr. E. 

 W. Shufeldt. 



The species is readily distinguished from texanus by many 

 characters besides the shape of the prothorax and the 

 antennal structure. The scales are much sparser in sulcatus and 

 are smaller and more elongate-oval. These scales are very 

 distinctly strigose in texanus^ and excessively, finely, and feebly so 

 in sulcatus. The median impressed groove of the beak is quite 

 different in shape in the two species, and in the present one the 

 eyes are distinctly more convex and prominent. 



STAimODERES n. gen. (Rrachyderini.) 



Head hemispherical, not at all impressed behind the eyes ; the latter 

 at more than their own length from the prothorax, oval, convex, and 

 very prominent. Beak rather slender, and much longer than the head, 

 nearly twice as long as wide, flattened ; sides parallel and straight i 

 alae slightly dilated. Occiput convex ; front flat, not separated from 

 the beak by a well-defined transverse impression. Scrobes lateral, 

 narrow, and deep, beginning at the ape^rand pursuing a straight course 

 nearly to the middle, then bent suddenly downward, evanescent in a
