SATYRUS II., I] I. 



At Martha's N'incvanl. distant alioiit seven miles iroiii the niain-hmd. and on 

 Nantucket, which is some fifteen miles further at sea. a small t'oiin is I'ound 

 which I have called var. Mar/flma. (II., Fig. 6.) It is verv Mack, and has a 

 reddish-yellow band, not a yellow one, as in Alope. Whether it is restricted to 

 the ishinds, or appears on the adjacent coast, I have not been able to ascertain. 



iVf^j/u>/e was described by Kirby as follows: "Wings brown; primaries, both 

 above and below, with a paler sub-marginal broad band, including two eyelets, 

 the upper ones surrounded by a paler atmosphere, with a black iris and white 

 pupil ; on the under side the atmosphere is most distinct and forms a kind of 

 glory round the eyelets." etc. Apparently this is a description of a female. Tlie 

 winss of the male are lilackish-brown. the ocelli are small, usually without rin<'-s, 

 and often without pupils. (III.. Figs. 1. 2 <?, :>. 4 ?. Canadian examples). 



There is a certain belt of latitude which includes most of the State of New 

 York and southern New England, in which Ijoth Alope and Ncplieh are found, 

 together with every possible intergrade. Towards the southern border of this 

 Ijelt. or in tlu' lowlands, as along the valley of tlie Hudson River. Alope pure type 

 prevails; in the Cat.skill Mountains, and to the northern border, pure JVejjhele 

 is found, but with Ncphele. in all its localities within the belt, are intergrades. 

 In the Catskills. I have taken Alope as conspicuously banded as any in Virginia, 

 but such examples are rare, forming, perhaps, two or three per cent, of the Hight. 

 These intergrades are distinguishable by the atmosphere about the ocelli. What 

 Kirby calls the '• pale " atmosphere appears in the males also, and in both sexes 

 gradual!}- widens and becomes less obscure till it culminates in a clear yellow 

 band, that is, in Alopie. (III., Figs. 7-13.) 



Of 7 <? JVejihele pure type, from Canada, all have 6 ocelli beneath hind wing; 

 of 10 9. 20 per cent, have G. GO per cent, have over 3, 10 per cent, have ; so 

 that there is an excess of ocelli in both sexes, but especially in the male, as com- 

 pared with Alope. 



The form which al)Oiuids in Illinois. Wisconsin. Nel)raska. and west to the 

 moiuitains differs a little from the greater number of JVephe/e. as seen in Can- 

 ada, though individuals are found there which are not distinguishable from it. 

 But a series of examples from Canada and one from Illinois will show a percep- 

 tible difference. The nuiles of this western form are almost l)lack. the ocelli are 

 very small and without rings; but in some cases there is a faint russet or yellow 

 glow about the ocelli, and perhaps this will suttase the space between them. On 

 the under side the rings are russet or ochraceous on both win^-s. The females 

 are nearly always dark, without the " paler atmosphere " mentioned by Kirby. 

 This is what I have called var. Oli/mpus. (III., Figs. 5, G.) But occasionally an 

 example appears with a pale yellow atmosphere about the ocelli, as in some in-
