MELITAEA MATA. 
Secondaries with a marginal row of lunules ; two broad bands, 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 ; primaries have three slight brown dashes, one at posterior angle, one at middle of 
interior margin and the other extends from middle of costa to first median nervule. 
Secondaries with markings of upper surface faintly repeated in very pale brown and yellow. 
Habitat. Rocky Mts. of Colorado. 
Mr. Reakirt described this from a unique 9 example, I know of no other in any collection. 
The peculiarity of colouration is remarkable, though not without precedent as in the case of Eresia 
Leueodesma,* E. Myia,f E. Ofella,| and some others, where the ornamentation is white on a dark ground. 
Mr. Reakirt’s impression was that the example was faded, in which conclusion he was incorrect, as the portion 
of the secondaries which is overlapped by the primaries, proved on examination to be exactly the same colour 
as the exposed parts, and the under side is equally pale with the upper ; 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 living authority on Diurnal Lepidoptera, 
to whom I sent a careful drawing of it assures me it is “ quite a stranger to him. ” 
SATYRUS HOFFMANI. 
Page 31, t. 4, fig. 8, 9 June (1873.) 
(PLATE VIII, FIG. 12, &) 
This species or variety, § as the case may be, was described on page 31 of this work, and t. 4, fig. 8, repre- 
sents the 9 ; I did not at that time figure the cT, considering the 9 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. Ent. Soc., and were distributed end of June, 1873. 
This description of S. Wheeleri I copy below, and accompany it by that of S. Hoffmani, S 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. 
Satyrus Wheeleri, n. sp. 
Male. Expands 2.3 to 2.5 inches. Upper side light yellow- 
brown, clouded with dark brown, especially on the disks of each 
wing, the dark portion forming a broad band on primaries, a nar- 
row one on secondaries well defined outwardly but within fading 
insensibly into the ground colour; hind margins edged by a pale

1 1 hold thatS. Alope, Nephele, Pegala, Boopis and Hoffmani are but forms of one and the same, the stem of which was S. Alope. 
Between the darkest examples of Nephele and Boopis there is really no difference in appearance whatever; they are both the same 
colour, both have the ocelli on upper surface primaries of female surrounded with a cloud of paler colour, both are 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 
more up to the full completoment, as the case may be. Between S. Pegala and Nephele 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 and still more conspicuous one of S. Pegala ; my remarks regarding under surface of S. Nephele and Boopis apply equally well 
to that of S. Alope. In S. Pegala and S. Hoffmani, 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 goes, are always present; regard- 
ing the spots of upper side of primaries, they seem to be subject to no very particular rule, (except in the case of S. Hoffmani, where 
there are always two, the upper one of which is geminate ;) half of the examples of S. Pegala, S 9> before me have one spot, the upper 
one, only on primaries, the remaining half, S 9 > differing in no other respect, have two equally large and precisely like the northern 
S. Alope; as to the latter, I have it marked on upper surface, primaries, with two spots, 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, though not joined together, but distinctly separated by 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 Hoffmani), regardless of sex, either 
entirely wanting, or a mere speck, 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 I have examined, any indications of a second or third smaller spot accompanying it, except in Hoffmani, 
where there is always a second, and sometimes a third one. 
Satyrus Hoffmani, n. sp. 
Male. Expands 2 inches. Upper surface uniform brown of 
as deep a shade throughout as in the darkest examples of S. 
Alope, S. Nephele or S. Sylvestris. On the primaries are two 
ocelli, black with small white pupils, the one nearest the costa is 
geminate, being joined with a smaller one at its lower edge. On
