THE CANADIAN ENTOMOLOGIST. 35 



Vanessa, Grapta, Argynnis, and Euptoieta. Papilio Troilus, plate 7, is 

 simply atrocious. I doubt very much if any one not familiar with the 

 butterflies could identify several of the species of Thecla from the figures, 

 and I am sure they could not identify many of the Hesperians. And the 

 drawing is of the roughest. 



In giving a title, the author should have respected the claim of Mr. 

 Scudder, who, as all the world knows, has been engaged for years on 

 " The Butterflies of N. E.," and is about publishing the same. 



Whenever in this book larvae or habits are treated of, there are pretty 

 sure to be errors, both of commission and omission, and this is inexcus- 

 able, as in nearly or quite every instance, careful descriptions of the pre- 

 paratory stages and habits were or could have been before the compiler. 

 The result is such as to destroy largely any value the text might have. 

 Thus: 



Under N. Ca?ithus, we are told that the larvse are green. Now there 

 are green larvae, but so far as has been observed, the larger number are 

 buff. See Can. Ent., xv., 64. Also it is said of this species that the 

 larva moults three times in fall, then hibernates, and moults three times in 

 spring. No butterfly larva moults six times, and those treated of vary in 

 habit. Some moult twice and hibernate, then three times in spring, while, 

 other larvae go to pupa in one season with but four moults. 



Of JV. Eurytris, we read : " Larva not dissimilar to that of Alope, but 

 smaller." There is no near resemblance whatever between the larvas of 

 these two species in any stage, but a great and generic difference. 



Of D. Archippiis, we read that the larvae moult three times, whereas 

 they moult four. See Psyche, ii., 53. 



Of Arg. Cybele : " The earlier stages of this species are not very well 

 known. The larvae have been kept in confinement by Mr. Edwards, and 

 moulted five times, and during the winter went into the chrysalis state." 

 I gave full account of all stages of the larva, Can. Ent., xii., 141, and 

 therefore the early stages are very well known, and a life history, vol. vi., 

 p. 121; and the pupation took place, not in winter, but in May. 



L. Disipptis : Larva described as having a horn on second ring, and 

 on third, fifth, etc., a spiny process each, the eleventh with two short 

 spines. Now every ring mentioned here has a pair of processes instead 

 of a single one. In the account of the habits of this species, not a word 

 is said of the case made by the larva for hibernating. On the contrary, 

 we have the incorrect statement that the larvae remain in pupa all winter.
