rower than the base, deeply sinuate, the transverse base just visibly 

 and broadly bisinuate; surface moderately convex, very finely, 

 sparsely punctate becoming gradually deplanate (cf ) or concavo- 

 deplanate (9) and coarsely, densely punctate laterally; apical and 

 basal margins narrowly, closely and rather strongly punctate 

 throughout the width; scutellum small (cf) or well developed (9 ), 

 equilatero-triangular; elytra short, barely one-half longer than wide, 

 three-fifths to three-fourths wider than the prothorax, also wider 

 than the latter basally, broadly rather depressed suturally, widest 

 at the middle, rapidly acuminate behind, the sides strongly arcuate, 

 less so basally, the marginal carina very strongly, subvertically 

 reflexed basally, gradually more feebly thence posteriorly, disap- 

 pearing at basal sixth to medially (cf ) or at about basal fourth 

 (9), the surface smooth, sometimes feebly creased, sparsely, very 

 minutely punctate; abdomen nearly smooth, the punctulation 

 scarcely visible, the punctures small and sparse but distinct apically; 

 propleura not or scarcely rugulose, minutely, sparsely and asperu- 

 lately punctate, the prosternum almost similarly or more finely so. 

 Length (c?) 11.0-12.0, (9) 14.0 mm.; width (cf) 5.2-5.9, (9) 

 6.7-7.0 mm. Arizona (Huachuca Mts.) cochisensis n. sp. 



Prothorax even smaller than in cochisensis, the tarsi similarly very 

 slender, the posterior slightly longer than in the female of that 

 species. Form ( 9 ) less stout, deep black and much less shining, in 

 fact very nearly as opaque as in pinalica, the head somewhat feebly 

 impressed, densely opaque, only moderately punctate; prothorax 

 very slightly wider than long, nearly as in cochisensis, except that 

 the sides are rather less broadly concave and less strongly punctured, 

 the reflexed edge thinner and the apex less deeply sinuate; elytra 

 fully two-thirds longer than wide and fully three-fourths wider than 

 the prothorax, the oblique sides in apical two-fifths much more 

 gradually converging and nearly straight to the more acute apex, 

 in basal two-fifths moderately converging and feebly arcuate, the 

 reflexed edge extending between a fifth and sixth from the bluntly 

 rounded humeral angles; surface nearly as in cochisensis though 

 opaque and with the punctures much less minute but extremely 

 feeble; abdomen nearly similar, the last segment more narrowly 

 rounded. Length (9) 14.5 mm.; width 6.4 mm. Arizona (Hua- 

 chuca Mts.), Chas. Schaeffer gracilipes n. sp. 



Prothorax quadrate, relatively much larger; hind tarsi much stouter than 

 in cochisensis or gracilipes. Form nearly similar but less ventricose; 

 head nearly similar, the punctures not quite so coarse, well separated; 

 antennae nearly similar; prothorax slightly wider than long- 

 counting the medial length as usual, for the sides are as long as the 

 width; sides parallel and only very slightly arcuate, continuing 

 equally so to the apical and basal angles, the former blunt but 

 advanced, the latter somewhat more than right but sharp, not 

 prominent; apex but just visibly narrower than the base, deeply 

 sinuate; base almost rectilinearly truncate; surface nearly as in co- 

 chisensis but more alutaceous or subopaque, the minute punctures
