156 THE BUTTERFLIES OF NEW ENGLAND. 



completing its cycle of changes ? It would hardly seem possible that Holm- 

 gren's young caterpillars could feed up in the spring to appear upon the wing 

 at the early date of their normal appearance in Sweden. Oris it another in- 

 stance of the greater intensity of life in America ? The brief and regular time 

 of the butterfly's flight would seem to indicate uniformity in the larval habits, 

 and the unusual temperatures to which the northern insect was subjected 

 may account for that exception in which the caterpillars did not survive. 

 Search for the butterfly should l)e made in the first half of June in all 

 sphagnum morasses in northern New England and Canada to learn more of 

 its distribution ; it is useless to search for it outside of such a spot. North- 

 western subarctic America should also be searched. Does the pupa under- 

 go its transformations in a cell as in O. semidea, or hanging like ordinary 

 Nymphalids? Fyles does not tell us. Has the creature any parasites?

Imago (52:4). Head small, pretty iniiformly tufted with rather lona: hairs ; front 

 full, depressed a little above, protuberant in the middle below, scarcely nan-ower than 

 the eyes, broader than high, the middle of the upper posterior border projecting 

 roundly a little between the antennae, lower edge rather abrupt, pretty well rounded; 

 vertex small, depressed, the anterior edge corresponding reversely to the posterior 

 edge of the front; flanks pretty full; upper border of the eye distinctly angulated op- 

 posite the posterior base of the antennae. Eyes of moderate size, pretty full, naked. 

 Antennae inserted in the middle of the head, in a broad, shallow pit separating the 

 front and vertex, their interior bases in close contiguity and the exterior edge striking 

 the flanks; considerably longer than the abdomen, composed of from forty to forty- 

 five joints, increasing very slightly and very gradually in size on the apical third, the 

 last two joints diminishing to a broadly rounded apex; transversely circular, the club 

 a little depressed, minutely carinate along the under surface. Palpi more than twice 

 as long as the eye, slender, compressed, the apical one-third as long as the middle 

 joint; profusely clothed beneath with long, above with short hairs, all compacted in 

 a vertical plane.
