212 MEMOIRS ON THE COLEOPTERA 



3 Elytra distinctly elongate 4 



Elytra short, barely longer than wide, more coarsely and deeply sculp- 

 tured; color bright rufous, the surface polished 5 



4 Color piceous-black, the under surface and legs dark piceous, shining; 

 head very small, a fourth as wide as the prothorax, finely, deeply and 

 densely punctate, the clypeus more finely and sparsely and feebly 

 rugulose; tubercle high, obtuse, rounded, not laterally attenuated 

 though slightly transverse; clypeus trapezoidal, the sides sinuate 

 basally, the apical carina only slightly reflexed, rather deeply sinuate 

 transversely and a little less than half the basal width; prothorax 

 four-sevenths wider than long, widest at basal fourth, the sides 

 strongly converging and feebly, evenly arcuate to the apex, rounding 

 inwardly at base, the obtuse basal angles moderately rounded; apical 

 angles rather sharp, the apical sinus circularly rounded as usual; 

 punctures strong, deep and very dense anteriorly and not different, 

 though less dense, postero-laterad, much smaller and sparse pos- 

 teriorly, the median line punctureless almost throughout and, 

 toward base, feebly impressed; scutellum smooth, very feebly 

 concave medially; elytra oblong, parallel, the sides almost evenly 

 and broadly arcuate, the apex circularly rounded, only about a fifth 

 wider than the prothorax and slightly more than twice as long; 

 punctures widely separated, rather coarse, feebly impressed, the 

 long shallow annuli well defined, the series only very slightly im- 

 pressed; pygidium finely, closely, irregularly punctulate throughout, 

 equally strongly at apex medially, becoming less finely rugulose 

 toward the ends, the lower bead wide, flat, the inner groove inter- 

 rupted at the middle in the type. Length (9) 16.8 mm.; width 

 10.0 mm. New Mexico (Fort Wingate) ovalis n. sp. 



Color obscure castaneous, moderately shining, not much paler beneath; 

 head but little more than a fourth as wide as the prothorax, finely, 

 densely punctate and feebly subrugulose, the tubercle transverse and 

 obtuse, obsolete within lateral fourth; clypeus in form nearly as in 

 the preceding, the apex in the type much worn down, the resulting 

 flat surface posteriorly angulate, with a small median sinus at apex, 

 a form seemingly impossible to derive from the apical part of ovalis 

 if similarly worn down; the central tubercle, also, is much thinner 

 antero-posteriorly than in ovalis and laterally less abbreviated; 

 prothorax nearly as in ovalis in form and sculpture, except that the 

 punctures are not quite so coarse and much shallower, the sides at 

 basal fourth more angularly subprominent and the punctureless 

 unimpressed median line more punctate anteriorly; scutellum ogival, 

 perfectly flat and smooth; elytra less elongate, a sixth longer than 

 wide, nearly a fifth wider than the prothorax, the sides less parallel, 

 feebly inflated behind the middle, circularly rounded at apex, the 

 punctures similarly rather coarse, shallow, elongate annuli but not 

 impressed, the series unimpressed; pygidium finely, closely punctato- 

 rugulose, smooth and with minute punctures medially toward apex, 

 the lower bead broad and flat, the groove uninterrupted as usual. 

 Length (9) 16.6 mm.; width 10.3 mm. New Mexico (Santa Fe).
