white in color with two large transverse areas of black at the base of the pro- 

 notum and two smaller and feebler at the middle, the elytra with numerous 

 isolated or partially anastomosing black spots throughout the extent; head 

 densely', the beak more sparsely clothed witli short narrow sijuamules. Head 

 three-fifths as wide as the prothorax, without a fovea but with a rounded spot 

 of pale scales between the eyes, the latter remotely separated; beak short and 

 stout, not as long as the prothorax, bent downward and feebly dilated toward 

 tip, finely, densely, rugosely punctate, with a single fine and feeble dorsal 

 carinula; antenna; rather short and thick, inserted at outer third or fourth, 

 the second funicular joint not quite twice as long as the first and but slightly 

 longer than the next three, the third longer than the fourth. Prothorax small, 

 slightly wider than long, the sides arcuate; apex truncate, more than three- 

 fourths as wide as the base, which is but feebly arcuato-truncate; ocular lobes 

 moderately developed; disk evenly convex, finely, sparsely punctate, each 

 puncture with a small suberect stout hair. Scutellum small, not conspicuous. 

 Elytra one-half longer than wide, scarcely three times as long as the prothorax 

 and one-half to neai'ly two-thirds wider, parallel and straight at the sides, 

 gradually obtusely rounded behind, humeri rounded to the prothorax, exposed 

 at base; subapical umbones obsolete; disk finely striate, the stripe very finely, 

 scarcely distinctly punctate, the intervals feebly convex, finely, sparsely punc- 

 tate, each puncture bearing a stout erect and strigilate hair. Abdomen thinly 

 clothed with short stout hairs, squamose toward the sides, strongly and closely 

 punctate; legs moderately long, the femora more densely squamose and swol- 

 len distally but narrowed near the tip; hairs short, erect and sparse. Length 

 5.3-6.5 mm.; width 2.25-2.85 mm. 



Colorado (Denver). Mr. Hugo Soltau. 



A small but distinct species, quite conspicuous in maculation ; 

 it was taken by Mr. Soltau in considerable numbers. It may be 

 placed near rotundicoUis in the arrangement recentl}^ proposed by 

 LeConte (Proc. Am. Phil. Soc, XY, p. 128.) 



PLECTROMODES n. gen. (Phytonomini). 



Body oval, very convex and sparsely pubescent, the elytra 

 acutely' prominent at the sides behind the humeri. Head sub- 

 globular, moderatel}^ inserted, the eyes scarcely convex, trans- 

 verse, distant from the base, somewhat coarsel}' faceted, mode- 

 rately separated above, remotely so beneath, truncate anteriorly, 

 gradually' obtusely pointed beneath. Beak short, thick, cj'lindri- 

 cal, feebly dilated toward apex, the scrobes extending almost to 

 the tip, becoming partially visible from above, obliquely descend- 

 ing toward base and terminating at the lower angle of the e^'e. 

 Antenna? inserted near the apex of the beak, the scape slender, 

 extending to the base, enlarged at apex; basal joint of the funicle
