parts of the uterus. But I doubt if there are any observations on that 

 point at present." That seems a reasonable explanation. 



V. Argynnis Atlantis, p. 578. It is said: "The early history of 

 this species is almost wholly unknown, the different stages of the cater- 

 pillar and the chrysalis never having been adequately described." I had 

 this species from the egg, and described every stage, egg, larva and 

 chrysalis, in Can. Ent., XX., p. i., 1888, in the manner usual with me ; 

 and as Mr. Scudder has copied my descriptions of other species by 

 wholesale, I am at a loss to see" what there is "inadequate" in this of 

 Atlantis, or why it is dismissed so curtly. 



VL Colias Eurytheme,T^. 11 26. Under the division of ^z/rj'^/zi?/;/^- 

 Eriphylc comes the species Harfordii H. Edw., and its var. or co-form 

 Barbara, and reference is made to the description and life history of 

 same, with plate, in Butt. N. A., V., 3. I showed in the paper cited 

 that the male Harfordii comes near C. Interior Scudder, a species 

 which the discoverer regards as genuine ; and that the var. (or co-form) 

 Barbara approaches the Eurytheine group, i. e. Eurytheme and Philodice, 

 and I said, " So that the species in certain points resembles species 

 belonging to two distinct sub-groups." Dr. Hagen, Trans. Bost. Soc. N. 

 H., 22, 165, 18S3, judged Harfordii to be neither more nor less than 

 Interior. Mr. Scudder might have compared the genitalia, as he believes 

 in those organs as tests of species, and told us wherein Harfordii 

 resembles Eurytheme. 



VII. Limenitis Disippus, called Basilarchia Archippus. There is 

 so much in this life history that is at variance with what I myself have 

 observed in West Virginia, that one would seem to be dealing with a 

 distinct species, and that the New England form could not be the same 

 as the Virginian. 



Page 261. The protection of the egg from " ants, mites and spiders 

 * * * is undoubtedly in the fewness of their number on one plant. 

 The spider that finds two eggs of a Basilarchia in one day must be an 

 excellent hunter." In this region there is no limit to the number of eggs 

 that may be laid on one tree. The seedling plants of aspen are often 

 full of eggs or larvae. On one occasion I found four larvae on four leaves 

 of one little stem ; on another I found eleven eggs and young larvje on a 

 plant not over eighteen inches high, nearly one to every leaf; on another 

 I found nine eggs on a small tree. I once discovered a female oviposit-
