Flavidalis of the same species has the hind wings yellow instead 

 of orange. Var. Bunkeri of Cerogavia has the median field of 

 the primaries more or less suffused with brown, against which 

 the white sub-rcniform stands out in relief ; the hind wings have 

 the yellow band half narrower than in the type and the yellow 

 base to the wing disappears. This variety is very beautiful in 

 extreme examples and is named for Mr. Robt. Bunker of Ro- 

 chester, who has devoted much attention to the species of this 

 genus. Var. PJialanga of Palceogaina is readily recognisable 

 by the subterminal space being filled in with black contrasting 

 with the white s. t. line ; it is figured by me in the Proceedings 

 of the Entomological Society of Philadelphia Vol. 3, Plate 3, 

 fig. I. Var. Basalisoi Hnbilis, differs by the presence of a black- 

 basal streak on the primaries above. Var. Wcstcottii of Anna, 

 differs by its smaller size and the black band of secondaries along 

 the border being continuous and not inter^pted as in the type 

 before anal angle ; the variety is from Illinois. Var. Sordida of 

 Gracilis, differs from the type in having the primaries wholly of a 

 dark hoary blue-gray ; it has been collected by Dr. James S. 

 Bailey in large numbers about Albany, N. Y., and is readily dis- 

 tinguished. Finally, var. Lineella of A mica differs by the darker 

 shades on the forewings being gathered along the lines, giving 

 the insect a distinct appearance, as compared with the type, 

 while the ground color is powdered with greenish gray. This 

 occurs with the typical form; in Texas another variety of Arnica 

 occurs in which the primaries are more or less suffused with 

 black : Mr. Hy. Edwards calls this Var. Nerissa. Excluding 

 Communis and Snowiana,"^ to the value of which I am doubtful, 

 I have named ten varieties. 



NEW SPECIES OF HETEROCERA. 



By Hekry Edwards. 

 FAM. SPHINGID^. 



Proserpinus CiRC.'E. n. sp. 



In form and outline of the wing very closely resembling the 

 California species, P. Clarkiw. Bdv. but abundantly distinct in 

 color. The primaries are of a reddish olive tint, the basal 

 space, and that behind the median band being the palest. The 

 band is rich, deep olive brown, almost straight on its anterior 

 edge, sinuous on its posterior, leaving the costal termination 

 twice the width of that of the internal margin, and enclosing a 

 rather darker ovate discal spot, shaded posteriorly with paler 

 color. Secondaries dull chestnut red, with the base and margins 

 darker than the centre of the wing, the basal shade being in the 

 form of a band. There is no trace of a black band, as in P.
