Mr. Godman adds the two following species — Thecla adeno- 

 stomatis, H. Edw., and T. Senrici, Grrote, both of which appear 

 to have been taken in Siskiyou County : the specimen of the latter 

 species is unusually tawny in colour.

 and well marked.

I am quite willing to adopt the name M. eurydice rather than 

 use that of M. Wosnesenshii for this beautiful insect ; and there- 

 fore I follow Mr. Edwards in admitting the Eeport of the Secre- 

 tary of the Erench Entomological Society upon Dr. Boisduval's 

 exhibition. But this Eeport, which briefly characterizes the spe- 

 cies, can in no way be fairly quoted as Boisduval's ; in fact there 

 is not a particle of evidence to show that the worthy Doctor did 

 more than exhibit the specimens, and express his intention of 

 describing them at a future time. It appears, however, that the 

 Secretary, M. Desmarest, by the insertion of a brief comparative 

 description in his report, was just in time to save the name pro- 

 posed by M. Boisduval, though at the same time unintentionally 

 depriving him of his species : had M. Boisduval placed a written 

 description in the hands of the Secretary, he would have retained 

 his authorship. It is a singular fact that M. Boisduval quotes 

 the volumes for both 1854 and 1855, and p. lii instead of p. xxxii 

 of the latter volume. In these errors he has been followed by both 

 Edwards and Kirby.
