8 li, eximillS n. sp. — Almost evenly elliptical, rather convex, black 

 throughout, the antennre rufescent with the club dusky ; integuments strongly 

 shining ; pubescence dense in the lateral vitta of the prothorax and elytra, 

 elsewhere very short, sparse and rather inconspicuous. Head convex, very 

 finely, sparsely punctate, with a small deep circular interocular puncture ; 

 beak slender, cylindrical, not very arcuate, but little shorter than the protho- 

 rax, almost completely impunctate, glabrous, the scrobes extending scarcely 

 to the middle, the antennfe inserted at two-fifths from the base. Prothorax 

 fully one-third wider than long, the apex three-fifths as wide as the base, the 

 latter very broadly, feebly angulate ; sides convergent from base to apex, 

 feebly arcuate, rather distinctly swollen at apical third ; disk evenly, trans- 

 versely convex, minutely, somewhat closely punctulate and with rather widely 

 scattered moderately coarse punctures. Elytra scarcely wider than the pro- 

 thorax, twice as long as wide, evenly, ratlier strongly rounded behind, with 

 a minute sutural emargination ; sides parallel and. nearly straight in basal 

 two-thirds ; disk with unimpressed rows of coarse rather distant punctures, 

 the series becoming strongly impressed near the apex ; intervals extremely 

 minutely, feebly, sparsely punctulate ; scutellar impression very short and 

 feeble. Abdomen rather strongly but sparsely punctate, sparsely clothed with 

 longer hair which becomes dense along the sides toward apex. Legs short, 

 stout, sparsely pubescent, the femora with a very small tuft of white hair 

 near apical third. Length 5.3 mm. ; width 1.8 mm. 



Texas (near Austin). 



This is one of our smallest species, and is notably distinct be- 

 cause of its almost evenly elliptical form, lateral vitta, smooth im- 

 punctate beak and subbasal insertion of the antennae. It is repre- 

 rented before me by a single specimen, probably a female. 



9 X. tenellUS n. sp. — Slender, subcylindrical and convex, polished, 

 black throughout, the tarsi and antennte rufous with the club of the latter 

 dusky ; vestiture dense in the lateral thoracic and elytral vitta, elsewhere 

 very short and sparse, broadly denuded along the lateral vitta and throughout 

 the median parts of the pronotum, also broadly subdenuded along the middle 

 of each elytron. Head convex, very finely, sparsely punctate, with a minute 

 interocular fovea ; beak almost as long as the prothorax, strongly arcuate, 

 slender, cylindrical, finely but strongly, extremely sparsely punctate, the 

 antennae slender, inserted just behind the middle, the scrobes just attaining 

 the middle. Pi-othorax almost as long as wide, cylindrical, the base very 

 feebly, broadly lobed, sides parallel and nearly straight, convergent near the 

 apex, the latter truncate ; disk finely, rather sparsely punctulate, also very 

 coarsely, somewhat closely punctato-foveate, a narrow median line impunctate. 

 Elytra nearly two and one-half times as long as wide, three times as long as 

 the prothorax and scarcely perceptibly wider than the latter ; sides parallel 

 and straight, narrowly parabolic at apex ; disk with unimpressed rows of 

 moderately coarse, not very distant punctures which become much smaller 

 toward apex, where also the first and second series become slightly impressed ;
