A Similar to consors but slightly less convex and with more parallel 

 elytra, the eyes similar, the antennae ( 9 ) longer, stouter and more 

 strongly serrate, nearly three-fifths as long as the body, the last 

 joint similar but very nearly as long as the preceding, feebly 

 beveled on the inner side in apical two-fifths, with a small pit 

 at the summit of the bevel; prothorax similar but with the median 

 teeth rather more reflexed; scutellum similarly very obtusely and 

 broadly rounded; elytral punctures much less distinct, being very 

 fine, feeble and everywhere remote, the fine raised lines rather 

 more distinct; tarsi similar in structure but notably stouter. 

 Length (9) 46.0 mm.; width 16.5 mm.. New Mexico (Jemez 



Springs), Woodgate acomanus n. subsp. 



B Similar to acomanus but with a still smaller head and rather less 

 widely separated eyes, the antennae not so long, notably more 

 slender and less serrate, nearly as in consors but still more slender, 

 the last joint (9 ) only about twice as long as wide, not beveled 

 apically and without trace of pit, much shorter than the pre- 

 ceding joint; prothorax throughout as in consors but more finely 

 and less strongly punctate; scutellum differing from either of the 

 two preceding in being fully as long as wide and narrowly and 

 evenly parabolic in form; elytra paler testaceous, otherwise as in 

 acomanus in form and punctuation, the raised lines still more 

 distinct; tarsi as in consors, more slender than in acomanus. 

 Length (9) 40.0 mm.; width 15.5 mm. New Mexico (Fort 



Wingate), Shufeldt proximans n. subsp. 



Form much more slender and small in size, pale testaceous in color, 

 strongly shining; head small, the eyes separated by less than three- 

 fifths their width, the ocular width much greater than the temporal; 

 antennae (cf ) red-brown, moderately stout basally, gradually finely 

 tapering distally, extending to apical fifth of the elytra, the last 

 joint very long and slender, fully five times as long as wide, parallel, 

 as long as the preceding but much narrower, truncate at apex, not 

 beveled apically; prothorax unusually small, short and transverse, 

 nearly as in consors but still shorter and more finely and sparsely 

 punctate; scutellum moderate, obtusely rounded; elytra rather 

 rapidly tapering from base to apex, with but very feebly arcuate 

 sides, the apices rather narrowly rounded, more than three-fourths 

 longer than wide and more than a third wider than the prothorax; 

 punctures rather large, deeply impressed, conspicuous though 

 widely, very unevenly separated; abdomen unusually slender and 

 tapering, the apical sinus simple; tarsi slender, especially the poste- 

 rior as usual. Length (cf ) 31.0 mm.; width u.o mm.; length and 

 width of prothorax 3.8X8.5 mm. Arizona (Canon of the Colorado 



River), Prudden '. angustulus n. sp.

acutely prominent externally and anterior to the line of the base. . 20 



Hind angles not oblique, right, rather blunt and in line with the basal
