ON CERTAIN NORTH AMERICAN SPECIES OF SATYRUS. 



BY W. II. EDWARDS,

1. Satyrus Pegala, Fabrieius, III, 494. 



Morris, Synopsis, &c. 

 Var. Alopc 9 , Boisd. and Lcc. 



In the collection of Mr. John Akhurst, of Brooklyn, are two speci- 

 mens, part of an invoice of twelve, that were received some years since 

 from Northern Georgia, and which, I have no doubt, are the Pegala, 

 of Fabrieius, a species that has been lost sight of or considered as only 

 a variety of Alopc. 



Both these are females and differ from Alope 9 principally in bav- 

 in": but one ocellus on the fore wings, and in size, measuring 2 -A 

 inches in expanse, while the largest Alope I have been able to obtain 

 measured but 2 T 5 . The baud on fore wings is broad, light buff in 

 color. The hind wings have one ocellus above and six below, and in 

 these and in other respects, these specimens closely agree with the de- 

 scription of Pegala. Mr. Akhurst tells me that all the twelve showed 

 but the one ocellus on the fore-wing. He regarded them at the time 

 as a distinct species, and therefore, carefully preserved the two that 

 fell to his collection. The others were sent to Europe by the collector. 



(Since the foregoing paragraphs were read before the Society, I have 

 been able to see the male of Pegala by the kindness of Mr. Grote. 

 Several fine males are in his collection, taken this season by Mr. Hi- 

 dings, in Georgia, which State appears to be the home of the species. 

 These males are all of large size, 1 T 5 inch in expanse, similar to the 

 females above mentioned, having one ocellus on the fore wing, one on 

 the hind wing above, and six beneath on the latter. These last cha- 

 racterize all the specimens of both sexes that I have seen, and are well 

 developed, divided always into two groups of three, of each of which 

 the middle ocellus is large. On one of the males is a black dot upon 

 the fore wings, in position corresponding to the second ocellus of Aloj>< 

 and Nephele. The under surfaces of these specimens are beautifully 

 reticulated, and the brown ground color is more or less washed with 

 grey.)
