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

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

 isolated or partialh' anastomosing black spots thronghaut the extent; head 

 denseh', the beak more sparsely clothed with short narrow S([uamules. 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 Avide, scarcely three times as long as the prothorax 

 and one-half to nearly two-thirds wider, parallel and straight at the sides, 

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

 at base; subapical umbones ol)Solete; disk finely striate, the striai very finely, 

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

 tate, each puncture bearing a stout erect and strigilate hair. Ahdnmen 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 rotu7iclicoUis 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, moderately inserted, the eyes scarcely convex, trans- 

 verse, distant from the base, somewhat coarsely faceted, mode- 

 rately separated above, remotely so beneath, truncate anteriorly, 

 graduall}^ obtusely pointed beneath. Beak short, thick, cylindri- 

 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 eye. 

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

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