terior margin, and extending from near the apex parallel to the outer 

 edge, and a second broader one, quite faint, from the costal subapical 

 angle, formed by a succession of blotches. A third and fourth each 

 nearer the base, often wanting, or represented only by a nebulous 

 spot on the costa. A marginal row of fuliginous internervular dots, 

 on the secondaries becoming subtriangular. Secondaries with all 

 except the basal band of primaries continued, becoming more nearly 

 linear. The second from the apex has become a fuliginous series of 

 inward curves. Both wings marked with irregular blotches. Be- 

 neath dirty white, with a silvery lustre. Primaries with marginal 

 spots. 



Taken in West Roxbury, Mass., in April. Though the markings 

 are not distinct, but clouded, the species is easily recognized. 



Description of the Male op Limenitis Proserpina, By 

 C. P. Whitney. 



On the 4th of July, 1868, I captured near Lake Tanapus, in 

 Brookline, N. H., a female L. Proserpina. Agreeably to request of 

 Mr. Scudder, who very kindly loaned me a male for the purpose, 

 before I was aware I had one in my collection, I have compared the 

 6exes, and will notice here the chief points of difference. 



The band on the wings, which in the male is blue, and obsolete on 

 the primaries, in the female is light metallic green, extending across 

 both wings, becoming whitish on the primaries, but much wider on the 

 secondaries, shading almost to the base. The lunules are also green. 

 On the lower surface the band corresponds to that of the male, but is 

 much wider; greenish, instead of blue, and white, wide and distinct 

 on primaries. This band above and below is much more irregular in 

 its contour than in Arthemis, and on the secondaries extends nearer 

 the margin, as in Ursula, between which and Arthemis it seems to 

 form a connecting link. Male expands two and three fourths inches. 

 Female three and one fourth.
