edly as a smaller form of C. Myrmidone." Mr. H. Edwards, 

 Colias, p. 3, states : " By some great error of judgment, it has 

 been considered by Professor Zeller to be only a form of Myrmi- 

 done, which wants the gland at the base of the secondaries, so 

 strongly characteristic of C. Meadii." Perhaps Mr. H. Edwards' * 

 species was not C. Myrmidone, at least in series before me from 

 Europe and Asia, every male has the gland just as C. Meadii. 

 Though I have before me C. Meadii with a discal spot instead of 

 the streak, I cannot see that both species are identical. 



6. C. Behrii. 



From the highest mountains in California. I have only one 

 specimen. 



7. C. Hecla. 



From Greenland ; in Europe from N". Lapland. 



I have none before me, and chiefly compared Guenee, Ann. S. 

 E. Fr., 1864, p. 198, who had before him the types of this and the 

 next species. 



8. C. Boothii. 



From Boothia Felix by Ca])tain Ross. Only 3 £ and 49 were 

 brought home. One of the types is now in Dr. Staudinger's col- 

 lection. I am not aware that a specimen is present in any 

 American collection. The excellent description by John Curtis 

 with beautiful figures in Captain Ross voyage and the description 

 by Guenee are the only ones for this species, 

 vlts var. Chione one male from the same locality. 



9. C. Nastes. 



From N. E. Labrador and its var. Rossii from Boothia Felix. 

 I have only one couple before me. C. Werdwandi Zett. from 

 Lapland is stated to be the same species. W. H. Edwards, N. 

 A. Butt, Vol. ii, Colias, pi. i. 



Postscript. 



Mr. A. Keferstein the well known veteran of the lepidopterologists has 

 published a paper on Colias in Wien. Z. B. Ges. 1882, p. 449. I am 

 indebted to Mr. S. H. Scudder for the use of a separate copy, as the 

 volume has not yet reached this country. In the introduction of this paper, 



!Mr..H. Edwards asks me to state, that all his Myrmidone possess the gland and thus 

 his statement quoted above is erroneous; cf. also H. Hagen, Nature, 1883, No. 715, p. 244.
