Body densely covered with short, robust, cinereous hair, be- 

 neath which the surface is dull reddish, inclining to cupreous ; 

 punctured : scutel dusky, sparsely hairy : elytra with very small, 

 profound punctures, which are more distant from each other than 

 the length of their diameters ; tip attenuated equally from the 

 suture and exterior edge ; a little produced, and terminating 

 acutely. 



Length less than two-fifths of an inch. 



Very similar to a smaller species which Mr. F. N. Melsheimer, 

 in his catalogue, names piJosus ; but the elytral punctures of that 

 insect are much more crowded. 



CHRYSOMELA of Authors. 



1. C. HYBRiDA. — Ferruginous ; elytra pale yellow ; suture and 

 three lines on each ferruginous. 



Inhabits Missouri. 



Body oval, punctured, ferruginous : thorax irregularly punc- 

 tured, and with large, confluent punctures each side : scutel im- 

 punctured, rounded at tip : elytra, with the suture and three 

 lines, rufous; the intermediate line undulated, and united [450] 

 to the exterior one at base, and abbreviated at tip : wings pink 

 red. 



Length more than three-tenths of an inch. 



Very much resembles G. exdamatioais Fab., but, besides other 

 differences, the exterior elytral line is not interrupted ; in the 

 color of the thorax it approaches Fabricius' description of that 

 species. Brought from the Missouri by Mr. T. Nuttall. 



2. C. MULTIPUNCTATA. — Ferruginous ; thorax yellow, with a 

 ferruginous curve ; elytra yellow, with numerous green spots. 



Inhabits Missouri. 



Head and all beneath ferruginous ; thorax yellow, with a ferru- 

 ginous, irregular, arquated line and basal edge, including an ob- 

 solete dot : elytral with a sutural line, and numerous, irregular, 

 green dots and abbreviated lines, and immaculate, exterior mar- 

 gin : wings rosaceous. 



Var. a. Suture with a common, ferruginous fillet. 



Size of C. pMladelpliica, which it closely resembles ; but, al- 

 though it varies much, it may always be distinguished from that
