Five specimens are under examination. The species belong' to the 

 homo(/ena series ami is perhaps nearest to (/lennyi, than whicli it is con- 

 siderably smaller, differing also in color. It is not unlike a Perigea 

 allied to pulverulenta at first sight, and except for the structural char- 

 acters it would most naturally be referred there. 



SciilNiA HGE/E, n. sp. (Fig. 46, 2). — Ground color n bright, though i)alo Intcous, in 

 some cases with au admixture of browu. Head and thorax immaculate, abdomcu 

 more smoky. Primaries with the median space white, or whitish with a yellowish 

 tinge, else of the ground color. The darkest shades are those preceding the t. a., 

 and following the t. p. lines, and these lines are marked only by the color contrasts 

 between the spaces. T, a. line outwardly augulate, forming nearly a right angle. 

 T. a. line very evenly and equally bisinuate. S. t. line faintly traceabh' in some 

 specimens as an irregular white shade, but usually obsolete. Ordinary spots obso- 

 lete in most of the specimens, the reniform indicated in others. There is a series of 

 terminal dots which is evident in mosc specimens. Secondaries smoky to blackish. 

 Beneath, primaries smoky, the margins whitish, secondaries white. 



ExjJands 23-28""" ; 0.92-1.12 inches. 



HahHat. — Argus Mountains, April, 1891. 



Eight specimens are before me, and others not differing in appear- 

 ance are in the National Museum. The anterior tibii^e are furnished 

 with one inner and one outer short, stout claw at tip, and the nearest 

 structural ally is ^S'. spinoscv. There is a considerable variation in size^ 

 but otherwise the specimens are very much alike and very simx)ly 

 marked. 



ScHiNiA iNTRABiLis, n. sp. (Fig. 46, 3). — Ground color pale luteous, with an oliva- 

 ceous shading in the darker parts of the wings. Head and thorax immaculate, 

 the abdomen somewhat paler. Primaries with the median lines whitish, broad, the 

 median space i^aler than the other parts of the wing, and with white powderings, 

 which are most evident along the costa. The t. a. line starts from the base below 

 the median vein, extends along it about half way to the end of (he cell, makes an 

 abrupt curve and thence runs inwardly oblique, to the hind margin ; the pale median 

 shade therefore extends above the median vein to the base of the wing. T. p. line 

 from the costa a little before the apex, rigid to vein 5, then with a gentle incurve, 

 reaching the hind margin a little before the anal angle. S. t. line broad, pflle, 

 straight, followed in some specimens by vague venular points. The reniform is 

 indicated by a blackish shade, visible from the underside through the wing. Sec- 

 ondaries white with a yellowish tint, with a large black discal lunule, and a blackish 

 outer border which is interrupted at the middle of the margin by a pale shade. 

 Beneath whitish ; primaries with a very large, jn'ominent discal spot and sometimes 

 an incomplete submarginal line ; secondaries immaculate or with a discal sjiot, some- 

 times also with traces of an outer line. 



Expands 23-24"^'" ; 0.92-0.96 inch. 



Hahit at.— Death Valley, April, 1891. 



Three specimens, representin g both sexes, are before me. Fortunately 

 one of them boasts of one fore tibia, on which are 2 inner- and 4 outer 

 claws, the 4th shorter than the others, and the species is thus related 

 to the eastern S. rivulosa, albeit quite different in color. The species 

 should be easily recognized from the course of the t. a. line which does 

 not cross the wing, but bends back abruptl}^ and runs to the base be- 

 fore crossing the median vein from below. The t. p. line is also abnormal
