Elongate-oblong, subparallel. Metallic olivaceous, moderately shining; 

 under surface and hind femora piceous, bronzed ; antenna?, front and mid- 

 dle legs, hind tibia- and tarsi reddish-yellow, the outer joints of antenna- 

 fuscous at tips. Thorax one-half wider than long, sides moderately curved; 

 ante-basal impression narrow but. deep, extending from side to side; surface 

 distinctly alutaceous, finely and sparsely punctate. Elytra more than twice 

 as long as wide, sides parallel to apical third, thence rounded to tips; sur- 

 face sculptured as mentioned in key. Length 3-3.5 mm. 



Described from eleven specimens taken in Lake and Stark e 

 counties. May 19-September 27. Occurs on low herbs in damp, 

 sandy localities. From fiiscixtix't this may be at once separated 

 by the much longer, more parallel and less convex elytra, which are 

 at the same time less shining, more strongly alutaceous and much 

 more finely punctuate on basal half. The thorax is wider, with 

 deeper ante-basal impression. Named in honor of Frederick Knab, 

 of Washington, D. C., who has given me much aid in my study of 

 the Chrysomelidae. 



//. l)urt/cssi Crotch, length 1.5-1.8 mm., is a southern form

This genus contains two small species, one of which has been 

 taken in the State, while the other doubtless occurs. They have

 between the eyes ; antennas slender, longer than half the body, first 

 joint stout, second small, oval, third twice as long, joints 3 to 10 

 equal ; thorax convex with a vague transverse basal impression ; epi- 

 pleura reaching nearly to sutural angle; front coxal cavities open 

 behind ; first joint of hind tarsi as long as the next three.
