2O2 MEMOIRS ON THE COLEOPTERA 



Body smaller, much less stout, elongate-oval, dark, blackish-piceous in 

 color, pale red-brown beneath, rather shining; head nearly as in the 

 preceding, except that the transverse carina forms a broad sinuate 

 curve from side to side, the ends not separated from the side margins; 

 clypeal teeth peculiarly minute but otherwise normal; prothorax 

 not very transverse, only slightly more than one-half wider than 

 long, the sides and angles as in the preceding, except that the former 

 are less oblique either basally or apically; pit deep, oval, the tubercle 

 obtuse; punctures rather strong and sparse, small and sparser 

 medio-laterad and almost wanting along the median line; scutellum 

 barely wider than long, smooth ; elytra distinctly elongate, moderately 

 inflated just behind the middle and there distinctly less than a fourth 

 wider than the prothorax, evidently more than twice as long as the 

 latter; series broadly and distinctly impressed, the punctures not 

 very coarse but distinct and impressed, more confused externally and, 

 toward apex, slightly smaller though much less obviously so than 

 in the male of spissipes; pygidium minutely, sparsely punctate, very 

 finely and feebly rugulose along the base; hind tibiae scarcely twice 

 as long as their apical width, much shorter than the femora; hind 

 tarsi rather longer than the tibiae. Length (d 71 ) 12.0 mm.; width 

 6.85 mm. Texas (near El Paso), Dunn brevipes n. sp. 



20 Pygidium very minutely and remotely punctate, with a few more 

 distinct though sparse punctures toward the lateral ends. Body 

 oblong-oval, rather less convex than usual, polished, pale rufo- 

 ferruginous almost throughout, the head and antero-median part of 

 the pronotum black or blackish; head of the usual size and sculpture, 

 the carina even and long but not attaining the sides; prothorax 

 short, three-fourths wider than long, trapezoidal, with feebly sub- 

 prominent arcuation at the sides beyond the middle, the basal angles 

 rather broadly rounded; anterior pit shallow, the tubercle small; 

 punctures rather small, sparse, subevenly distributed but becoming 

 very shallow, sparser and feebler postero-laterad; scutellum moder- 

 ate, obtusely ogival, evidently punctate throughout, except at the 

 margins and medio-basally; elytra subquadrate, slightly elongate, 

 parallel, very broadly rounded at apex, more than a fourth wider than 

 the prothorax and nearly two and one-half times as long, the punc- 

 tures rather small but widely impressed, not close-set in the not dis- 

 tinctly impressed series, fine and confused apically; legs short; hind 

 tibiae a little more than twice as long as their apical width; last 

 ventral of the female smooth and virtually impunctate. Length ( 9 ) 

 13.7 mm. ; width 8.3 mm. New Mexico (Santa Fe) . . laevicauda n. sp. 



Pygidium distinctly though sparsely punctate though often somewhat 

 closely; upper surface of the body more convex. California. . . .21 



21 Body very stout, subpyriform-oval, large in size, polished, pale 

 castaneous in color, the legs and under surface still paler rufous; 

 head slightly larger than in the preceding, two-fifths as wide as the 

 prothorax, densely and confluently punctate, smooth at base, with 

 discrete punctures intermediately, the carina long, very thin, not 

 attaining the sides and feebly sinuate at the middle; clypeus finely, 

 very densely punctato-rugulose throughout, the subapical teeth
