196 THE CANADIAN ENTOMOLOGIST. 



relieve us from the imputation of having described " not the species, but 

 the individual',' placed upon us by the late Mr. Walsh in the case of D. 

 perspicua. And as to the " very limited number of specimens," the 

 argument which covers two pages seems to have been compiled almost 

 wholly from Fitch and other writers who mixed up a variety of forms 

 under the name of ministra, and who, in consequence, cannot be considered 

 as any authority on the subject. I have yet to see imagos of Datana 

 which I cannot refer to one or the other of the forms in this genus, which 

 are separable also on larval characters. It matters little whether we call 

 these forms " species " or " varieties," so far as the advisability of 

 according them different Latin designations is concerned. 



NOTES ON CERTAIN SPECIES OF ARCTIA. 



BY A. R. GROTE, BUFFALO, N. Y. 



Arctia arge (Drury). 



A male specimen taken by the late Mr. C. T. Robinson, at Brewster's, 

 N. Y., varies by the fore wings being black, the veins broadly bordered by 

 flesh color. The ordinary triangulate black interspaceal markings have 

 all fused. Hind wings shaded entirely with blackish, none of the usual 

 spots being visible. Beneath as above. Body as in the type. 



Arctia Anna Grote. 



Contrary to Mr. Stretch's remark, two specimens of this species 

 occurred in Perm. One is in Dr. Packard's collection, and is recorded 

 by him in his Synopsis. The markings of the fore wings prevent the 

 idea that it is a " melonotic ' : var. of Persephone, as suggested by H. 

 Strecker. Persephone Grote was described after this species; I supposed 

 at first the two belonged as <J and % , only one sex of each being known 

 to me. More material is needed to decide these points, bare opinions 

 being useless and offensive. 



Arctia Mich a bo, n. s. 



$ . Belongs to the series of virgo, Saundersii (intermedia), Edwardsii, 

 Blakei. The size is next to Saundersii. It is like virgo in having black 

 spots on the middle of hind wings, one rounded one on the median vein
