punctate in basal half, the punctures finer behind the middle; other 

 intervals uneven and scarcely punctate; color testaceous, with the 

 suture and side margin slightly darker; pygidium moderately coarsely 

 punctate, more densely laterad; under surface and legs testaceous; 

 metasternum clothed not densely with long hairs; abdomen shining, 

 scarcely punctate and with only a few hairs; front tibiae with a single 

 external tooth and apical process, the inner anterior claw (cf ) finely, 

 very unequally cleft, the upper ramus very short and scarcely 

 visible, the intermediate claws entire, not cleft. Length (head 

 porrect), 10 mm. New Mexico antennata Schf. 



Clypeus almost perfectly flat, its edges abruptly but more or less nar- 

 rowly reflexed 2 



2 Body elongate-oval, convex, shining, pale luteo-flavate above and 

 beneath, the head rufous, the pronotum with the two black spots 

 oblong, extending from the apical margin to basal third, somewhat 

 swollen postero-externally and separated by a parallel pale vitta, 

 the elytra with the sutural interval, and somewhat wider external 

 margin, of a sharply defined black; head densely punctato-rugose, 

 the occiput and clypeal margins with well separated punctures; 

 clypeus fully twice as wide as long, feebly arcuate at apex, with 

 broadly rounded angles, the sides very feebly diverging basally, the 

 reflexed edge very narrow, obsolete basally; eyes ( 9 ) very moderate, 

 the antennal club small, not quite as long as the preceding five joints; 

 prothorax distinctly less than twice as wide as long, the sides very 

 evenly arcuate and moderately converging throughout, the apex 

 deeply sinuate, with right and slightly blunt angles, the basal angles 

 obtuse, moderately rounded; surface convex, finely but distinctly, 

 sparsely punctate, a little more strongly laterad; basal bead very 

 fine, entire, at the foot of a short, rapidly rising convex slope through- 

 out the width; scutellum finely but closely punctate, more sparsely 

 centrally, the black sutural coloration narrowly surrounding it; 

 elytra fully a third longer than wide, not distinctly wider than the 

 prothorax, parallel, with slightly arcuate sides and circularly rounded 

 apex, the striae feebly impressed, widely and evenly spaced medially 

 and laterally, but with the second and humeral intervals broader 

 and in great part confusedly punctate, especially toward base; 

 strial punctures not very coarse but deep and very distinct: all the 

 intervals nearly flat; pygidium piceous, convex, shining, the arcuate 

 scratches sparse, very short and subpunctiform; sterna with rather 

 long loose pubescence; inner anterior claw (9 ) moderately slender, 

 cleft at tip, the upper ramus extending slightly beyond the lower, 

 the same claw of the intermediate tarsi longer and more slender, 

 with the apical notch linearly about half as large. Length ( 9 ) 

 9.0 mm.; width 4.4 mm. Arizona (Somerton) . . . .tenera n. sp. 



Body much smaller and still more slender, with still thinner integument, 

 very pale luteo-flavate throughout the body and legs, the head alone 

 pale piceo-rufous, the pronotum with the two small elongate nu- 

 bilous brown anterior spots, parallel, well separated and occasionally 

 obsolete; head finely, feebly, sparsely and irregularly punctate or 

 feebly rugulose throughout, the clypeus very moderate, short, some-
