which beyond it is silvery gray. Hind vnngs silvery gray, tlic black spots of the 

 basal t!iree-<niarters of the upper surface repeated distinctly as roundish black spots, 

 encircled narrowly with wliito, and, in addition, a similar spot in the costo-subcostal 

 Interspace, midway between the base and the spot next beyond it; the orange band 

 next the outer border is repeated beneath, separated narrowly by silvery gray from 

 the black edged border, but the black spots enclosed in its exterior border are much 

 smaller tlian above; a similar scries of black spots borderstheinterioredgeof the band, 

 occurring in the interspaces as far as the lower median nervule, edged interiorly with 

 white; they occur also in the costo-subcostal, the upper subcostal and the submedio- 

 interual interspaces ; fringe much as on the upper surface. 



Abdomen purplish black above ; the lower portion of the sides with frequent brown- 

 ish fulvous scales; beneath white, tinged with yellowish toward the tip; the male 

 abdominal appendages (34 : 37) having the lateral alations strongly compressed, 

 slightly twisted outward at the band, their tips very bluntly pointed ; tips of the deli- 

 cate lateral arms acicular, upcurved. Clasps reaching beyond the alations of upper 

 organ, the tip scarcely produced, bent Inward and scarcely downward. 



Described from 8^5?. 



Accessory sexual peculiarities. Besides the difference between the sexes in the 

 coloring of the upper surface of the wings, described above, this same surface shows 

 in the male some untoothed scales, not found in the female and therefore probably to be 

 regarded as androconia (46 : 34). They are asymmetrical, long oval in shape, about two 

 and a half times longer than broad, slightly broader on distal than on proximal half, 

 rather broadly rounded at tip, the basal lobe of one side very prominent and the stria- 

 tions more or less oblique. 



Egg (65 : 19) . Cells on the sides disposed somewhat regularly, so that one may trace 

 rows directed upward and to the left at an angle of sixty-five degrees with each other ; 

 the cells are the interspaces between conical protuberances with regular rounded sum- 

 mits, .0763 mm. apart, each connected with the adjacent ones by athin wall, partitioning 

 the cells, wliich mounts more than half way up the sides of each elevation ; they produce 

 the efl'ect of stellate ridges, in the middle of the sides vei'y regular, six-rayed, but 

 above exceedingly irregular, then more frequent, changing gradually in appearance by 

 the enlargement of the centre and the diminution of the rays, until on the upper sur 

 face the egg is white and uniform, pitted with little roundish and oval cavities, about 

 .04 mm. in diameter; the conical elevations, at the greatest, are about .04 mm. and 

 the partition walls about .0127 mm. in diameter. Micropyle pit (68 : 13) .0763 mm. in 

 diameter, the central cell circular, .003 mm. in diameter, the large cells surrounding it 

 six or seven in number, oval, their longer diameter directed toward the centre and 

 .013 mm. long, their shorter diameter .01 mm. ; the secondary cells nearly circular, 

 .0085 mm. in diameter; the whole net work of cells is very slightly raised above the 

 surface and very indistinct. Color pale green. Height, .4 mm. ; breadth, .84 mm. 



Caterpillar. First stage. Studied after death only. Head fuscous, with black 

 ocellar field. Body apparently dusky yellow, bristles pale. The upper longest bris- 

 tles are .44 mm. in length and the spicules excessively minute, though larger than in 

 E. epixanthe. The shorter superior bristles are .165 mm. long; the lateral bristles 

 are .14 mm. long and only .00425 mm. broad at base, while the spicules are minute, 

 less than half as long as the diameter of the base of the bristles. Length estimated at 

 .9 mm. 



Chrysalis (84 : 50). Light yellowish brown sometimes an aureous tinge, the tongue 

 a little darker, and the inner sides of the legs and the interspaces of the wings rather
