THE CANADIAN ENTOMOLOGIST. 155 



Habitat, Western Washington. 



Described from 55 (? , 21 $ . 



This is the most northern of the orange tipped group of Anthocharis. 

 It is found from the Willamette Valley in Oregon to Vancouver in British 

 Columbia, and from the Pacific Ocean to the Eastern slopes and spurs of 

 the Cascade Range of mountains in Central Washington, but in Eastern 

 Washington and Idaho it is replaced by A. stella. Its metropolis is in 

 the densely fir-forested country west of the Cascades, and about Puget 

 Sound, where it is fairly abundant. The (J is a little larger than A. 

 reakertii, and with broader wings and more pronounced black markings ; 

 and the marginal marbling in even blocks along the venules is distinct. 

 The $ is deep lemon yellow, the colour being even and uniform rather 

 than discal. This species is also rather peculiar in that the ? is of 

 smaller average expanse than the ^ . 



CORRESPONDENCE. 



CATOCALA AMIGA, HUBN. 



Z>ear Sir : I notice that Mr. Hulst refers luieella as a synonym of 



this species. It is not a synonym, but a well marked variety, constantly 



recurring with the typical form. I remember that my earlier opinion that 



it might be a distinct species was shared by W. H. Edwards, as well as 



other lepidopterists. On the other hand Mr. Hy. Edwards's herissa, 



referred by me as a variety, Check List, p. 40, is a suffused Southern 



form of Arnica, no two specimens being exactly alike (as is the case with 



lineelia), and giving one the impression as if the species had run out in 



Texas. I do not know if it is found in Mexico. Lineelia must be restored 



as a perfecdy recognizable variety of Arnica. I embrace this occasion to 



repeat my opinion that Alabamce is a valid species, as also to protest 



against the identification oi fratercida, G. & R., with micronympha, 



Guen. I believe also that when residua and Meskei come to be bred, 



their specific validity will abundantly appear. I have had to rescue 



praedara, dulciala, crataegi, and other species from Mr. Hulst's errors in 



cabinet opinion. It is not necessary for me to lose one word over Mr. 



Hulst's rejection of Euparthenos and Audrewsia as valid genera. 



Very respectfully, 



A, R. Grote.
