Setondaries with a marginal row ol' limules ; two broad bauds, separated by a dark line, and the exterior 

 one enclosing a row of small brown crescents, occupy the outer half of wing ; within the discoidal cell is a 

 large white spot divided by a dark line. 



Under surface white ; j)rimaries have three slight brown dashes, one at posterior angle, one at middle of 

 interior margin and the other extends frf>m middle of costa to first median nervule.

Habitat. Koeky Mts. of Colorado. 



Mr. Keakirt described this from a unique 9 example, 1 know of no other in any collection. 



The peculiarity of colouration is remarkable, though not without precedent as in the case of Eresia 

 Leucodesma,* E. Myia,t E. Ofella,^ and some others, where the ornamentation is white on a dark ground. 

 Mr. Reakirt's imjiression was that the example was faded, in which conclusion he was incorrect, as the portion 

 of the secondaries which is overla])ped by the primaries, proved on examination to be exactly the same colour 

 as the exposed parts, and the untler side is equally pale with the upj)er ; besides the example was never ex- 

 posed, having passed from the collector's hands, who had his specimens in papers, direct to Mr. Reakirt and 

 finally to me, in no instance was it ever exposed to the continued action of light. I at first thought it might 

 be an albino variety of some species or other, but on a rigid comparison with the analogous species I cannot in 

 the least identify it with any of them, and Mr. Hewitson, the greatest livingauthority on Diurnal Lepidoptera, 

 to whom I sent a careful drawing of it assures me it is "quite a stranger to him. " 



SATYRUS HOFFMANI.

(PLATE VIII, FIG. 12, c?.) 



This species or variety,§ as the case may be, was de.scribed on page 31 of this work, and t. 4, fig. 8, repre- 

 sents the ? ; 1 did not at that time figure the rj^, considering the ? the most remarkable on account of its 

 conspicuous white under surface, but Mr. W. H. Edwards, on the receipt of that No. of this work, wrote a 

 few lines, informing me I had re-described his species, S. Wheeleri, the description of which was printed in 

 advance sheets of Trans. Am. p]nt. Soc, and were distributed end of June, 1873. 



This description of S. Wheeleri I copy below, and accompany it by that of S. Hoffmani, j^ and 9, and I 

 trust, that after a comparison of the descriptions and figures of the latter with the description of the former, 

 but little further need be added to prove that they are not the same. •

insensibly into the ground colour; hind margins pdged by a pale geminate, being joined with a smaller one at its lower edge. On

i I hold that iS. Alope, Kephele, Pegala, Boopis and Ilofl'mani are but forms of one and the same, the stem ol which was 8. .\lope. 

 Between the darkest examples of Nepliele and Boopis there is really no difierence in appearance whatever; they are both the same 

 colour, both liave the ocelli on upper surface primaries of female surrounded with a cloud of paler colour, both arc marked alike beneath, 

 neither are restricted to the six ocelli of under surface of secondaries, both sometimes are devoid of all these ocelli, or have only one or 

 raore up to the full conii)letemenl, as the case may be. Between .S. I'egala and Neiihele are all grades in the width of the yellow band 

 of primaries, which is found from the merest shade surrounding the ocelli up to the broad band of S. Alope, and from thence to the 

 broader uriil >till more eonsiiicuous one of S. Pegala ; my remarks regarding under surface of S. Xephele and Boopis apply equally well 

 to that of S. .Mojie. In S. Pegala and S. Ilofl'mani, where the forms (one in the west, the other in the east,) appear to have reached the 

 highest standard, the six ocelli of under surface, secondaries, as far as my observation of many examples goe.s, are always present ; regard- 

 ing the spots of upper side of primaries, they seem to be suiy'ect io no very particular rule, (except in the case of S. Hofl'mani, where 

 there are always two, the upper one of which is geminate ;) half of the examples of S. Pegala, (J' 9 , before me have one spot, the upper 

 one, only on ]>riuiarics, the remaining half, (j"' 9, diliering in no other respect, have two equally large and precisely like the northern 

 S. Alope; as to the latter, I have it maiked on upper surface, primaries, with two spot.-;, big spots, little spots, and with no spots 

 at all. On examples of one ? variety from California, allied to S. Boopis, on the upper surface the ocellus of primaries nearest the pos- 

 terior angle is double, thougli not joined together, but distinctly separated hy a dark line, the lowermost of the two is always the smaller, 

 and is unrepresented on the under surface. 



The ocellus on upper side of secondaries, near anal angle, is in all the forms mentioned, (except Hotlmani), regardless of sex, either 

 entirely wanting, or a mere sjieck, or from that on to the yellow ringed ocellus equal in size to those of the primaries ; nor can I find in 

 any examples of the many 1 liave examined, any indications of a second or third smaller spot accompanying it, except in Hofi'mani, 

 where there is always a second, and sometimes a third one.
