NORTH AMERICAN COLEOPTERA. Ill 



This species is closely allied to pedalis but is more robust and with 

 different male maxillary palpi ; ptdalis is nearly black above, the present 

 species luteous. Some specimens show an indistinct vitta on each ely- 

 tron of denser pubescence. 



Collected in Arizona by Morrison. 



C. mgritarsis Lee. has been placed by me (Proc. Am. Phil. Soc. 

 1873, p. 96) in error among the species with two terminal spurs in the 

 male, it has really but one and is therefore allied to i:>edalis and insignis 

 but is much more robust than either. It is similar in color to insignis 

 but has slender S maxillary palpi. 



E. Tallax n. sp. — Form slender, black, sparsely clothed with short black pu- 

 bescence. Antennae slender, setaceous, slightly compressed. Head shining, 

 coarsely but sparsely punctured. Thorax narrower than the head, much longer 

 than wide, somewhat campanulate in form, shining, coarsely but sparsely punc- 

 tate, a smooth space on each side behind the middle somewhat more convex. 

 Elytra much wider than the thorax, gradually wider posteriorly, surface sub- 

 opaque, rather densely punctate scabrous, sparsely pubescent, with three very 

 finely elevated lines on each side. Body beneath shining, moderately closely 

 punctate. Length .52 inch; 13 mm. 



The male has two anterior tibial spui's ; last ventral feebly emarginate. 

 Spurs of posterior tibiae slender and acute. 



This species by its characters is most closely related to Jissilahris and 

 corvimi from both of which in differs by its smaller size and much nar- 

 rower and longer thorax which is quite shining here and densely punc- 

 tured in both the others. In general appearance it resembles jnincticollis 

 and oblifa, which have filiform antennae. 



Occurs in Owen's Valley, California. 



CAIVTHARIS Linn. 



Canfharis cardinalis Chev. — From specimens shown me by Mr. Salle 

 this species belongs to my division of the genus in which the intermediate 

 joints of the male antennae are thicker. The name C. fulvipennis Lee. 

 should be restored to our species known under the preceding name, 

 excepting the sexual characters the two species ai'e very much alike. 



C inolesta n. sp. — Black, feebly shining, thorax red with a large basal spot 

 and narrower apical margin black. Antennae slender and long, the outer joints 

 gradually thicker. Head very sparsely punctate, with the usual vertical spot. 

 Thorax broader than long, sides arcuate in front, posteriorly oblique, very sparsely 

 punctate, color orange red with a large basal black spot extending in front of mid- 

 dle and tridentate in front. Elytra wider than the thorax, gradually broader pos- 

 teriorly, moderately closely punctate scabrous. Body beneath black, shining?
