sex ; the color is brown, covered with a beautiful purple gloss. 

 The spots on the anterior wings are in shape and color the same 

 as in the female. There are two white spots on each of the pos- 

 terior wings, one on the medial cell, opposite the limbus, as in the 

 female, and the other, twice the size of the latter, occupies the sub- 

 dorsal region. This spot is much larger on the under surface ex- 

 tending on the margo interior, and it is the distinctive mark 

 between the sexes. Dorsal part of the body tufted with white hairs. 

 Length 1-fg inch. 



On the 29th June, I captured both sexes of this species in the 

 Gomin swamp, near Quebec. Alypia resembles the ffesperida 

 in flight, but when at rest, they do not erect their wings like the 

 species of the latter family. It is very difficult to capture Alypia ; 

 three or four specimens may be considered a good day's work. 



The following note relating to this species, was received in Septem- 

 ber last, from Aug. K. Grote, Esq., of New York : — " Your note 

 and specimen of Alypia Langtonii, Couper duly handed to me. 

 I thank you very much for the specimen. This species is very 

 closely allied to Alypia S-maculata, with which you should com- 

 pare it rather than with A. MacCullochii, Kirby, to which latter 

 A. Ridingsii Grote, is nearer allied. A. Langtonii ? differs from 

 A. S-maculata ? merely by the slightly more prominent palpi, and 

 the presence of but one larger external .spot on the second- 

 aries. Kirby's species should be turned up by some of your 

 entomologists. The $ of Alypia S-maculata differs from the ? , 

 principally in that the inner larger spot on the secondaries is 

 extended to internal margin and base of the wing."
