328 MEMOIRS ON THE COLEOPTERA 



Form subcylindric, more elongate and still larger, darker red-brown in 

 color, moderately shining, sparsely squamose; head large; vertex 

 coarsely but not densely punctate, with some whitish scales laterally 

 and numerous long coarse brown hairs; clypeus very deeply concave, 

 much constricted at base, the angles sharp and prominent, the apex 

 broadly bisinuate; surface with sparse punctures and large scales, 

 smaller and dense apically; last palpal joint slender, with but few 

 small punctures, the outer side with a fusiform and strongly defined 

 flat rugulose area from basal fifth to apical third, the ends of which 

 are more acutely angulate than usual; antennal club large, between 

 three and four times as long as the stem; prothorax very convex, a 

 little more than twice as wide as long, as in all the preceding species 

 in outline but with the entire periphery finely deep black, the punc- 

 tures coarse shallow sparse and irregularly distributed, each with a 

 large yellowish-white scale, the impressed median line and short 

 sublateral basal vittae densely squamose; scutellum densely squamose 

 medially and basally toward the sides; elytra unusually rugose, large, 

 two-fifths to nearly one-half longer than wide, the scales whitish, 

 sparse, dense in two ragged inner discal vittae, the outer vitta un- 

 developed, indicated in very small part in only one example; pygidium 

 with small broad sparse scales; middle tarsi almost as long as the 

 tibia?, the posterior much shorter; three teeth of the anterior tibia? 

 well developed. Length 28.0-33.0 mm. ; width 14.0-15.0111111. New 

 Mexico (Albuquerque). Three examples sejuncta n. sp. 



Form much more abbreviated and less cylindric than the two preceding, 

 moderately shining, pale ferruginous, sparsely scaly, the scales white 

 or nearly so; head and clypeus nearly as in sejuncta, the erect pale 

 brown hairs of the vertex more slender; antennal club pale, very 

 strongly curved, between three and four times as long as the stem; 

 last palpal joint slender, sparsely punctate, the outer side narrowly 

 flattened and feebly roughened as usual to about apical third, but 

 with the flattened area not very well defined as it is in all the pre- 

 ceding species; prothorax strongly convex, twice as wide as the median 

 length, in form and general characters nearly as in the preceding but 

 a little shorter, the sides obtusely prominent and angulate just behind 

 the middle; surface with very sparse, moderate and shallow punc- 

 tures, each nearly filled by a short broad scale, the scales dense in 

 the narrow impressed median line and also in a narrow oblique 

 broken sublateral vitta and thence along the margin inwardly 

 for some distance; scutellum densely squamose broadly along the 

 middle; elytra a third longer than wide, about a fourth wider than 

 the prothorax, circularly rounded behind, feebly rugulose and feebly 

 sparsely punctate, each puncture with a small and rather narrow 

 scale, which is three times as long as wide, the scales dense along the 

 suture and in four vittae, the two inner the second and fourth 

 discal lines of scales, dense and subeven, the third very fine and only 

 visible for a short distance behind the middle, the submarginal feeble 

 and only evident behind the middle; pygidium sparsely and irregu- 

 larly squamulose; three teeth of the anterior tibiae strong; hind 

 tarsi short, very much shorter than in either the following or two
