smaller than the first; prothorax rather small, four-fifths as wide as the 

 elytra at the humeri, not quite twice as wide as long, the strongly con- 

 verging sides nearly straight, broadly rounding in apically; basal lobe 

 narrow, strong, arcuato-truncate at tip; surface minutely, not closely 

 punctulate, the pale hairs rather long and coarse, sparsely aggregated 

 toward the base and sides; elytra nearly a third longer than wide, arcu- 

 ately rounding at the sides in about apical third, the apex obtuse; punc- 

 tures rather small but strong, separated by three or four times their 

 diameters; ashy hairs forming a broad and very oblique fascia on each 

 near basal third, not reaching the sides or suture and also a transverse 

 subapical spot; under surface rather finely but strongly punctate, loosely 

 on the metasternum, densely and as usual more rugosely on the abdomen. 

 Length (9 ) 2.7 mm.; width 1.65 mm. Colorado (Golden), C. A. Frost. 



The position of this species is near the last and reversum, but it 

 differs from both in the oblique, loosely pubescent fascia on each 

 elytron; the subapical spot is still more loosely, or even sparsely, 

 pallido-pubescent. 



Cryptorhopalum pallens n. sp. Very evenly elongate-oval, convex and 

 shining, the type evenly pale testaceous in color throughout above, 

 somewhat more obscure beneath and on the head; pale vestiture yel- 

 lowish-cinereous and very coarse, more grayish beneath; head small, 

 finely but rather deeply, evenly and somewhat sparsely punctured 

 throughout, the ocellus large and very prominent; antennae (9) small, 

 ferruginous, extending through only apical third of the prothorax, the 

 club ovoidal, shorter than the basal parts and with its second joint 

 notably narrower as well as shorter than the first; prothorax scarcely 

 twice as wide as long, the sides strongly converging and very evenly 

 though not strongly arcuate from base to apex; basal lobe strong, sub- 

 truncate; punctures very fine, sparse; vestiture in great part denuded in 

 the type, but such as remains is pale and coarse; elytra two-fifths longer 

 than wide, obtusely oval, the humeral swellings only very moderate, the 

 punctures fine, separated by two or three times their diameters, the 

 surface smooth; vestiture in great part denuded in the type, but some 

 coarse yellowish-cinereous hairs remain behind the middle, apparently 

 enclosing a subapical area in which they become rather less pale and less 

 coarse; under surface very convex, not coarsely but closely punctate, the 

 metasternum gradually finely and sparsely so medially, the hairs con- 

 spicuous and coarse. Length (9) 2.35 mm.; width 1.35 mm. Texas 

 (El Paso), G. W. Dunn. 



I at first associated the type of this species with hcemorrhoidale 

 Lee., but the antennal club is distinctly different. In both that 

 species and reversum, the two joints in the female are exactly equal 

 in form and size; the cavity is relatively shorter in htemorrhoidale 

 than in reversum, being nearly as short as in pallens. There is no 

 doubt, from the antennal structure, that pallens is distinct from either
