346 REPORT OF NEW JERSEY STATE MUSEUM. 
C. amelia Knab. Chester, Newark Dist. (Bf); feeds on alder only 
(Knab). 
C. philadelphica Linn. Ft. Lee (Bt); Caldwell (Cr); Orange Mts. VI 
(Bf); Riverton V, 30 (GG); throughout Camden and Gloucester Co. 
IV-VI (div); Lahaway V-VII on “Cornus” only (Sm). 
var. spirsese Say. With the type and locally replacing it. 
C. bigsbyana Kirby. Throughout the State, more common northwardly 
V, VI on maple, willow and alder. The records credited to “multi- 
punctata” Say. in the last edition really belong here. 
It is quite likely that some of the records credited to “scalaris” and 
“Philadelphia” belong to Mr. Knab’s species, and that these are of wider 
distribution than here indicated.
