3O MEMOIRS ON THE COLEOPTERA 



very feebly submedially inflated; punctures rather strong but less 

 impressed, the series feebly impressed, nearly regular, the intervals 

 2-4-6 nearly similar but with the punctures sparser, not so coarse 

 on the second and confused near the sides; pygidium convex, the 

 short arcuate scratches rather feeble and sparse; inner claw of the 

 anterior male tarsi thicker than in ar-ida and much more deeply cleft 

 at apex, the upper ramus not very thin and extending almost as far 

 as the lower. Length (cf) 10.5-11.6 mm.; width 5.5-6.2 mm. 

 Arizona (Boboquivari Mts. and Cochise Co.). . . .papagoana n. sp. 



16 Body elongate-oval, convex, shining, pale testaceo-flavate, the head 

 and pronotum pale and uniform brownish-rufous, the latter broadly 

 and evenly flavate at the sides, with the dark spot diffuse; elytra 

 with the suture alone narrowly pale brown; head very large, two- 

 thirds as wide as the prothorax, the median part of the front and the 

 clypeus densely and rather finely punctato-rugose, the remainder 

 sparsely, rather finely punctate; clypeus short, trapezoidal, with 

 broadly rounded angles and narrowly and sharply reflexed edges; 

 eyes very large and prominent, separated by less than twice their 

 width; prothorax less than twice as wide as long, evenly trapezoidal, 

 with straight sides, becoming subprominent and arcuate in median 

 third; apex transverse, sinuate at each side, the angles not prominent 

 and with their tips blunt; basal angles but narrowly rounded, the 

 lobe rather pronounced, the bead very broadly interrupted medially; 

 surface minutely, feebly and very sparsely punctate throughout, 

 not at all sloping to the bead at base; in the type, there is at each 

 side near the apex, an oblique deep sulcus extending from the apical 

 margin not quite to the side margin, which may be accidental; 

 scutellum finely, sparsely punctate, except along the middle and at 

 the broad smooth margins; elytra long, fully two-fifths longer than 

 wide, broadly, feebly inflated except basally, circularly rounded in 

 about apical two-fifths, the punctures fine and feeble in slightly 

 irregular and unimpressed series, confused laterad, the itervals all 

 nearly flat, the second rather broad, with a median line of irregular 

 punctures, becoming sparsely diffused basally; pygidium convex, 

 the arcuate scratches feeble and sparse; larger anterior claw of the 

 male slender, gradually finely and somewhat obliquely pointed, with 

 an excessively short fine ramus on the upper side at apical third. 

 Length (cf) 9.8 mm.; width 5.0 mm. Arizona. .. .sagax n. sp. 



Body less elongate, shining, pale luteo-flavate throughout, the head pale 

 rufous, the pronotum (cf ) with a large semicircular brown spot at 

 apex, the diameter lying on the apical margin, or ( 9 ) wholly pale 

 red-brown, the side margins flavate; elytra with the suture alone pale 

 brown; head (cf) not quite three-fifths as wide as the prothorax, 

 densely punctate-scabrous before, sparsely puncate behind, a line 

 through the middle of the eyes, which are very prominent and separ- 

 ated by barely more than twice their width; antennal club not quite 

 as long as the stem; prothorax not quite twice as wide as long, the 

 sides slightly converging behind, and more so before, the more rounded 

 median part, the apex regularly sinuate, with rather sharp angles; 

 basal angles obtuse, narrowly rounded, the bead strong, sometimes
