Pennsylvania which will be better entitled to the name, and in that case 

 the present species will want a new name. 



It has been suggested that the European E. assimilata and E. 

 expallidata might occur here, but I am familiar with these two species, 

 and they are certainly distinct from the one under consideration. 



E. coagulata as here determined does not seem to be very abundant, 

 though widely distributed. 



My eastern specimens are all dated June. I have one from the 

 Catskill Mountains (June 3, 1899). It is species No. 10 of a series, kindly 

 sent me some time ago by Mr. R. F. Pearsall. I have it also from 

 Montreal, Ottawa and a number of other localities. 



Eup. gelidata, Moschler, Wien. Ent. Monats., IV, 47, i860. — This 

 species is placed on our lists on account of its occurrence in Labrador. 

 According to Staudinger and Rebel (No. 3634), it also occurs in Green- 

 land and the Shetland Islands. I have not seen it. 



It is said by the last named authors to be a variety of E. nanata, 

 Hubner, a common European (and British) species feeding on Erica and 

 Calluna. E. nanata is a Eupithecia, but Hulst places gelidata in 

 Eucyniatoge, relying on the supposed difference in number of accessory 

 cells, or more likely making a mistake through not having had specimens 

 for critical examination. 



The original description o{E. gelidata h copied in the Monograph 

 on pages 64 and 65. 



Enp. hyperboreata, Staudinger, Stett. Ent. Zeit., 400, 1S61. — Another 

 northern species that I have never seen. Apparently it is nearly allied to 

 the last named. The localities given in Staudinger and Rebel's Catalogue 

 (No. 3635) are Norway, North Germany, Russia and Greenland. 



Eup. anticaria, Walker, Cat. Lep. Het., Br. Mus., XXIV, 1241, 

 1862. — If it should turn out that the number of the accessory cells is a 

 constant character in this genus, then anticaria will have to be placed in 

 Eucyniatoge, for it certainly possesses the two cells. Walker described 

 this species and itnplicata and explanata all from Nova Scotia specimens, 

 from the collection of Lieutenant Redman. 



It seems to me probable that the three constitute but one species. 

 The description of anticaria comes first in Walker's work, and it certainly 

 applies to the common form which goes under that name in our collections, 

 and which occurs almost everywhere, from the Atlantic to the Pacific.
