described by Knab are undoubtedly distinct from scalaris, it is very 

 probable that a large series Avill show them to be varieties of one 

 species, rhoda.

372. 



Resembles rhoda closely in form and general color. 

 The pale area of elytra is much greater, the suture be- 

 ing pale with a narrow subsutural black line each side 

 on basal half and with two or three elongate dark spots 

 which represent the spurs or branches of scalaris. The 

 humeral lunule is much more narrow and less curved 

 than in rlwda and encloses both a shorter lunule and a 

 ^After°Knobel 2 ) small spot, while the other discal spots are smaller and 

 more numerous. Length 8-9 mm. (Fig. 502.)

Sci.. III. 1824, 450 ; ibid. II, 216. 



Resembles philadelphica very closely. Thorax yellow with several 

 small reddish-brown spots arranged in an irregular curved line near the 

 middle and often a darker, narrow, transverse basal spot. Elytra with nar-

XXXVIII. Chrysomela Linn. 1735. (Gr., ' < golden + fruit.") 



This genus, as now limited, contains oval convex species of me- 

 dium size having the elytra of one color and, in our species, the
