Taijgete. Bootes. &e., thereby accomplishing for North America what 

 Moschler has done for Europe ; and although T have not been able to 

 agree with that author in all his determinations, I hope I shall not be 

 found to have created confusion thereby. I have not attempted to give 

 any opinion upon purely European species, since, from the want of a 

 sufficient number of specimens from that continent, such an undertaking 

 would be misplaced, but where the Labrador species was one said to be 

 identical with the European, I have founded my judgment wholly on 

 the Labrador specimens and figures of Labrador individuals, and have 

 given, from all works at my command, synonymical lists, it will be seen, 

 only of descriptions and figures of, or references to, specimens from La- 

 brador, strictly confining myself to the American species. I do not 

 doubt, however, that some of them are found upon both sides of the 

 Atlantic, and have specimens of several under examination from Europe 

 and America which do not seem to me distinct. For these also I am 

 indebted to the favor of Mr. Edwards. But this field of inquiry being 

 extraneous to my purpose, I have not entered upon it. I have given 

 outline figures to illustrate the direction of both the borders of the 

 middle band on the under surface of the secondaries, using, when 

 sketching them, a specimen of each species which seemed to me to ex- 

 hibit the normal condition. 



A description of the egg, larva and chrysalis of one species, (C%. 

 semidea) with figures of the latter two, will be found in my "Remarks 

 on some characteristics of the insect-fauna of the White Mountains, 

 New Hampshire." published in the Boston Journal of Natural History. 

 Vol. VIL pp. (312— (331. 



One source of confusion and difficulty of understanding the meaning 

 of authors has been, it seems to mo. in the indifferent manner with 

 which they have frequently used specific names which in their view 

 were synonymous, leading others to believe that because, for instance, 

 they employed in one place the specific name Bootes and in another 

 Taj/ffete, therefore they believed that two species existed, when it was 

 only an irregular use of names which had been applied by different 

 authors to one and the same species. Another thing is still more re- 

 markable to me. however: Moschler, in his valuable article on the 

 Lepidopteran Fauna of Labrador, (Wiener Ent. Monatschr. IV) enu- 

 merates on p. 342 the species of Chiouohas found there as Jtitta Hiibn., 

 Taygete Hiibn.. Oeno Bd. and Bootes Bd., remarking, in connection 

 therewith, that he discusses their relation so fully in his paper on the 

 genus ChionohaK in Europe, that it is only necessary to give an enu- 

 meration of them ; and in addition thereto, criticizing Mr. Christophs'
