NOTES ON THE AMERICAN FORMS OF EUCHLOE, Hubner.

In answer to Dr. Butler's comments (Can. Ent., XXXI., p. 19) upon 

 my revision of the species oi Euc/t/oc (Bull. Am. Mus. Nat. Hist., X., pp. 

 235-248), I could state that Dr. Butler may possibly be right in consider- 

 ing creusa (var. elsa)., hyantis and lotta seasonal forms oi ausonides, but 

 with the present knowledge it is not possible to place them so, and for 

 this reason I concluded it would be best to allow the species to remain 

 distinct until more light could be obtained on the subject. At any rate, 

 I was certain that what we had labeled in our collections as creusa was 

 not Doubleday and Hewitson's species, which Dr. Butler definitely 

 asserts is my var. elsa. What seems to me strange is, how was it that 

 Edwards did not recognize the figure of creusa, sent to him by Dr. 

 Butler. Creusa (var. elsa) cannot be mistaken for either hyantis or lotta 

 (so-called creusa). Doubleday and Hewitson did not give a description 

 of creusa, and their figure of the species is unrecognizable, consequently 

 has no scientific value. E. olyinpia, I can assure Dr. Butler, is not a 

 Zegris, but belongs with ausouides. In the genus Zegris the head is 

 very thickly scaled and the palpi are very short, while in E. olyvipia the 

 palpi are long, and in all other respects it agrees with ausonides generic- 

 ally. Cethura and piina do not strictly belong to Midea as placed by 

 me. Mr. Grote erected the generic name Tetracharis for cethura (Proc. 

 Am. Phil. Soc, XXXVII , Jan., 1898, p. 37). In this paper, of which I 

 had no knowledge when writing my own, Mr. Grote referred the Ameri- 

 can species, with orange blotch in the male, to Eiichloe, with cardajnines 

 of Europe as the type, as proposed by Kirby, Scudder, myself and others. 

 He further states that the white species of both continents are slightly 

 more specialized and might be kept under the title of Ajithocharis, 

 consequently my conclusions, which were worked out independently, 

 are the same as those of my friend Grote. Dn Butler's remarks about 

 the venation are practically the same as mine, only that he counts the 

 veins differently. Mr. Grote has given excellent figures of the venation 

 of ausonides, cardamifies and cethura, to which the reader is referred. 

 Dr. Skinner, in his recent catalogue of North American Rhophalocera, 

 1S98, places thoosa as a synonym of Reakirtii. I can definitely assert 

 that it is the female of Julia. He also places stella as a synonym of 

 Reakirtii, but it is the yellow variety of the latter.
