the spot in the mi(klle of the cell and at eciual distances from it arc two not very large, 

 roundish or trigonal, yellow spots, the outer generally the smaller and situated midway 

 between the central orange spot and the apex of the cell ; opposite the inner one, in 

 the costo-subcostal interspace, is another one very similar to it ; and in the medio-suh- 

 median is a fourth, usually transverse, lying midway between the intra-mesial band 

 and the inner orange spot; occasionally an additional small, yellowish spot occurs 

 above the costal nervure just beyond the orange spot ; fringe as above. 



Abdomen blackish brown, the posterior half with a lateral inferior series of trans- 

 verse, sometimes nearly confluent, orange stripes, tipped superiorly with yellowish; 

 there is also a dorsal and a lateral series of small, round, yellowish spots, the latter 

 on all, the former on most, of the middle abdominal segments ; beneath there is a similar 

 but indistinct, though often confluent, ventral series of similar, but longitudinal spots, 

 and the long inferior clothing of the terminal segment is orange. When denuded, the 

 last segment of the male is scarcely shorter below than above, the appendages (34 : 3, 4) 

 protruding but a short distance. Lateral processes of upper organ a little de- 

 pressed, triangular, finely pointed. Clasps of equal length and breadth, the hinder 

 border broadly rounded, its convexity covered interiorly by a lamella thickly studded 

 with iiiturned bristles ; the upper posterior angle slightly produced and directed iuAvard ; 

 inferior basal process stout, directed backward and a little downAvard ; interior tooth 

 flat, triangular, very broad at the base and emitting two thorn-like blades, one shorter, 

 compressed, arching inward, the other longer, appressed, curving longitudinally back- 

 ward.

Aberrations. E. p. superba {Mel. phaeton ab. a superba Strecker, Catal. Amer. 

 Macrolep. , 125). A single male specimen of this species has been taken near Brooklyn, 

 Long Island, by Mr. G. D. Hulst, in which the "upper surface difiers but little from the 

 ordinary form, except that the two rows of submarginal white spots of secondaries 

 are confluent, forming but one row of wedge-shaped marks with the points toward 

 the base. Underneath the whole space, comprising the greater part of the wing, 

 between the ferruginous basal patches and narrow margin of same color, is pure 

 white, with the venation black." (Strecker.) This appears to be a case of partial 

 sufl'usion. 



E. p. PHAETHUSA (3Iel. phctethnsa Hulst, Bull. Brookl. eut. soc, iii : 77; iv, pl.l, fig. 

 6). The same collector afterward took in the same place a melanic male of this 

 species, which is the only case of the kind I have known. "The orange spots are 

 wholly wanting on the upper surface of the wings ; and beneath there are found only 

 the one near the base, and. almost obsolete, the one along the costa near the base" 

 (Hulst). 



Egg (64:37). Nineteen ribs, .07 mm. apart, rather faint, most prominent above; 

 surface covered with rather frequent shallow punctulations. Micropyle rosette 

 made up of pentagonal or hexagonal cells, the inner aud outer ones as broad as long, 

 the others elongated, increasing in size from the centre outward, much broader out- 

 wardly, the longest cells being .42 mm. long, the broadest .034 mm. broad and the cen- 

 tral ones .011 mm. in diameter. Color when first laid bright lemon yellow; in three 

 days it becomes strongly tinged with browniish, and in tw^o days more turns to a 

 decided brown below ; in another two days it becomes entirely purplish brown and 

 shoi-tly after deepens in color at the summit ; when a little more than a fortnight old, 

 the lower two-thirds begins to grow paler and in three or four days more it is entirely
