SATYRUS HOFFMANI.

line, preceded by a dars one, and at some distance by a dark 

 common stripe, sometimes macular on secondaries; primaries 

 have a broad extra-discal band as in Alope, but pale brown, in 

 which are two large black ocelli, the upper one ( in all cases 

 under inspection )sub-pyriform, as if two spots of unequal size had 

 been compressed into one, and encloses two white points ; the 

 lower ocellus is larger, reunded, with white points ; both are en- 

 closed in narrow yellow rings ; secondaries usually have three 

 ocelli, but sometimes the one next anal angle is wanting ; these 

 spots are placed on the sub-median and two next preceding in- 

 terspaces ; the middle one is round, about one-tenth inch in 

 diameter, with white point and yellow ring ; the others are usually 

 mere black dots. 



Under side whiteisli, covered with abbreviated brown streaks, 

 most dense from base to middle of disk on primaries, but equally 

 distributed over whole secondaries, both wings being crossed by 

 an irregular extra-discal brown stripe, besides which secondaries 

 have a second similar stripe nearer the base; the ocelli of pri- 

 maries as on upper side, but surrounded by broader and paler 

 rings which coalesce ; secondaries have three ocelli near costa, 

 the two outer ones small, round, tlie others oval all with white 

 dots and yellow circlets ; the three ocelli next anal angle distinct, 

 also with dots and circlets. 



Body yellow brown ; legs same ; palpi darker ; antennse brown 

 with fine white annulations; club ferruginous. 

 Female. Not known. 



secodaries towards the outer margin, between first and second 

 median nervules is another ocellus about one-fourth the size of 

 those on priu>,aries; between the second and tliird median ner- 

 vules is a small black dot or point. On all wings are indistinct 

 marginal and sub-marginal lines which except the ocelli and 

 usual furry sexual transverse dash of primaries, are the only 

 marks on the upper surface, and were it not for the double upper- 

 most ocelli it could not possibly be distinguished in appearance 

 from a dark example of S. Nephele. 



Under surface brown with some grey scales mixed, which gives 

 it almost the exact tint of the under side of S. Pegala, although 

 it does not look as smooth as in that species, more squamose in 

 appearance ; primaries have ocelli as on upjier side but surround- 

 ed by broad yellow ritig>, the one encircling the lower ocellus has 

 a small yellow spot emanating from its npper edge; narrow mar- 

 ginal and sub-marginal lines; an irregular narrow central brown 

 band; the whole surface, but especially the inner half, covered 

 with short transverse lines. Secondaries have six ocelli arranged 

 as in S. I'egala, in two rows of three each ; the middle one of the 

 row nearest outer angle, is oblong and produced into a point in- 

 wardly ; the others are round, all are encircled narrowly with 

 vellow and pupilled with white ; whole surface marked with 

 short brown streaks which tend towards segregation near the 

 outer margin ; an irregular much broken band or line crosses the 

 disc and a shorter one occurs half way in from this towards the 

 base. 



Body dark brown, same colour as upper surface. 



Female. Expands 2.3 to '1.5 inches. Upper surface pale 

 yellowish brown. Primaries, outer half, corresponding to the 

 yellow band of S. Alope, very pale and contains two large ocelli, 

 the uppermost one geminate as in male, and all surrounded with 

 yellow rings. The darker basal half where it joins the outer 

 paler part is well defined, but on the inner side it becomes lost 

 in the general ground colour, without any line of demarkation. 

 Secondaries with sub-marginal lines as on primaries ; an irregular 

 narrow brown mesial band; a black ocellus accompanied by a 

 black spot as in male, sometimes a third small black spot is 

 between the ocellus and inner margin near anal angle. 



Under surface white, ocelli and other markings precisely as in 

 male but sharper and better defined throughout. 



From one male and ten females taken by a natnralist of Lien- 

 tenant Wheeler's Expedition in 1871, at Owen's Lake Nevada. 



From nine males taken by the naturalists of Lieutenant 

 Wheeler's Expedition, 1871, between Cascade and Rocky Moun- 

 tains, but the precise locality not indicated. This fine species is 

 one of the largest, equalling the largest specimens of Alope, and 

 may at once be distinguished from any other North American 

 Salyrus yet known by its pale color and clouded surface, and by 

 the whiteish color of under surface, and conspicuous brown trans- 

 verse stripes. The Ocelli also are different from those of our 

 other larger species, having small white pupil.s, and the upper one 

 on primaries being peculiar in shape and doubly pupillated." 



After presenting the above two descriptions I thought I would have nothing to say, further, regarding 

 them ; but as I light my jiipe and cast the approving glance, peculiar to self-satisfied quill drivers, at what I 

 have written, like a flash it suggests itself, all at once, in the twinkling of an eye, as I look croisswise from 

 Mr. Edwards' description to mine, and from mine to Mr. Edwards', that this might be a most curious case of 

 crossed gynandromorphism, or mimicry, (of which the exotic species furnish so many instances,) where the 

 male of Mr. Edwards' species mimics the female of mine, and I suppose when the female of Mr. Edwards' 

 species (at present "unknown ") turns up, it will be found to look like the male of mine! " Wonderful, in- 

 deed, are the works of nature," as the philo.sopher, who daily sweeps the street crossings, observed whilst he gazed 

 wonderiugly and admiringly at the anatomy of a cat which he held aloft by the nape of the neck ; " wonderful, 

 indeed," he repeated, "for if the holes in the cat's skin had been but a little higher up, or a little lower down, 

 the cat's eyes would have been covered, and, consequently, the cat would have been unable to see."
