Related to C. exclamationis, but is smaller, with head and thorax more shining 
and less punetured; with the conjoined vitta more abbreviated behind there is no 
sutura] dot at the middle, and the epipleuræ are not ferruginous, except at the extreme 
margin. (sec. Rogers. l. c.) 
12. CHRYSOMELA INCISA  ROGERS. 
Oval, rounded, bronzed, ferruginous; thorax with coarse punetures; 
elytra pale yellow, with a broad blackish brown sutural vitta abbreviated 
at the base, a broad stripe narrowed at the humerus and not reaching the 
base, and a small dot at the base, and another at the tip; epipleurze dark.

Locality: One specimen from Kansas. 
This insect has the same form and size as C. pulchra, the punctures of the 
dark vitta and those of the external rows are, however, more distinct, and the form 
of the vitte are different. The sutural one is not prolonged at the base, but truncate 
anteriorly at the scutellum, which, as usual, is dark colored; at about two-thirds the 
length it is suddenly slightly dilated nearly to the apex. The outer vitta is a very 
broad spot extending three fourths the length of the elytra; narrowed before and 
behind, convex on its inner, but moderately emarginate on its outer surface about 
the middle. (sec. Rogers l. c.)
