freQuent, scattered, delicate black hairs, the veins ilarkor) reaching to just about the 

 middle of the wins, its exterior limit parallel to the outer border and usually extending 

 as far be.vond the cell as the width of an interspace, but sometimes only as far as the 

 cell itself; at the base a large roundish yellow spot, resting on and above the curve of 

 the costal nervurc ; two small yellow spots at the extreme base, on cither side of the 

 principal insertion of the nervures; the apical half of the wing is very brilliant by 

 reflected light, varying from bright olive green to dark metallic blue, scarcely tinged 

 with green; next the upper border of this Held, in the lower half of the wing, a few 

 pearly white scales are collected in the middle of the interspaces ; there is a submar- 

 ginal row of seven very large, irregularly roundish, uniform orange spots, occupying 

 the whole width of all tlie interspaces from the costal nervure to the inner border, 

 broadly bordered above and below and partially at the sides with velvety black, partly 

 obliterated by pearly white scales at the upper outer corner of the upper five spots 

 and at the lower outer corner of the fifth and sixth; the upper spot is situated 

 in the middle of the costo-subcostal interspace; the second a little beyond the 

 middle of the upper subcostal interspace; the inner border of the third and fourth in 

 the middle of the two succeeding ; the fifth in the middle of the outer half of the 

 upper median interspace ; the inner border of the sixth in the middle of the lower 

 median interspace ; and the inner border of the seventh striking the middle of the 

 upper half of the lower median uervule ; fringe interrupted as on the upper surface, 

 but tlie straw yellow infringes on the wing itself, forming lunate or irregular patches 

 of considerable size, usually more or less faintly edged with blackish. 



Abdomen above and on sides dark blue black, with blue reflections ; at the lower 

 border of the sides a series of rather small, triangular, yellowish spots at the tip of each 

 segment ; beneath the same and on each side a similar spot at the apex of each seg- 

 ment. Valves of male (35 :24, 25) scarcely so long as broad, gibbous, subtriangular, 

 roundly right-angled at tip, the upper border well-rounded, the lower nearly straight, 

 armed within at the extreme base with a vertical, median, arcuate, rather slender, 

 corneous ridge bearing a median and an inferior suppressed but rather stout denticle, 

 scarcely curving downward. 



Malformations. Many years ago I saw in the collection of Mr. H. Strecker a speci- 

 men with the wings of the left side curiously affected, probably by some accident to 

 the chrysalis. The fore wing had a rather deep rounded emargination in the middle 

 of the outer border; the hind wing had on the inner margin just before the anal angle, 

 a similar but much narrower, very deep and conspicuous rounded excision. 



Mr. Strecker reports (Butt. rel. agric, IG) that he has two examples ''in which 

 parts of three wings are male and part female." 



Secondary sexual distinctions. Besides the slight distinctions in the form of 

 the hind wing mentioned in the generic description, the middle tibiae of the male 'ire 

 slightly longer than those of the female. The same is the case with the antennae, 

 which are relatively longer in the male. But the most striking difference is in the 

 close reflection of the inner margin of the hind wing (43 : 19) over the submedian 

 nervure which is furnished on its exposed side with long bristles ; this forms a slit- 

 like semi-annular pocket (45 : 5) the opening of which is controlled by the free re- 

 flected margin, and whose walls upon both sides (45:4) are studded pretty uniformly 

 but not serially nor very thickly with fan-shaped androconia (46 : 42) having a moder- 

 ately short pedicel and an apically truncate, broad, ovate lamina with five or six promi- 

 nent diverging ribs : the pedicel is set in an infundibuliform socket (not shown in the
