 of male (33:22): upper orsjan moderately lariic, body compressed above and arched 

 as in atalaiita, toj^ether with the hook perfectly straiirht abovi-. Hook slightly shorter 

 than the body, depressed, two and one-half times longer than broad, taperins; until near 

 the tip Avliich is bluntly pointed. Inferior arms nearly straiiiht except in their first 

 a|)proach to each other, moderately stout, taperinii pretty re<iularly to a |)oint which is 

 minutely hooked. Clasps nearly twice as lonii' as broad, slisjhtly broader between the 

 upper and hmer posterior auirles than elsewhere, the inferior ediije stronirly recurved, 

 the posterior edii'e produced to a rii>ht anisic in tlie middle, the aui^le pointed and incurved, 

 the upper hinder aniile considerably produced and broadly rounded. Interior tinut-r 

 (ribbon) with the liasal half as in atalanta. beyond delicately taperinu; t(j a tine point, 

 sinuous, incurved and directed a little upward, scarcely attainins; the tip of the back- 

 ward extension of the clasp. In addition, orisiinatina; in the centre of the interior of 

 the clasp, is a lamellate, moderately broad, horizontal ridjuje, directed backward and 

 equal for a short distance, then becoming free, curviusi; inward and narrowing to a deli- 

 cate point beside the interior finger. 



Described from 10;? 16$ specimens. 



Egg. Short ovate, l>roadest in the middle of the lower half, the l)ase broadly 

 rounded, scarcely flattened, the contour of the summit beneath the ribs slightly convex. 

 Kibs varying from thirteen to sixteen in number, lannnate, extending from the upper 

 portion of the rounded liase to the crown of the ega'. increasing in height from below 

 upward, most rapidly above, where they are .05 mm. in height, though only .012.') mm, 

 high in the middle of the egg. The surface between the ribs smooth, glistening, 

 slightly concave, traversed by delicate cross lines ,02o mm. apart, which traverse also 

 the vertical rib.s, where, on the upper portion of the egg, they turn upward and at the 

 crest cause the ribs to become very distinctly serrate, especially above, but giving them 

 a beaded appearance throughout. The vertical ribs terminate on the crown abrtiptly, 

 leaving a free space .is mm. in diameter, in the middle of which in a saucer-shaped 

 depression is situated the micropyle .1 mm. in diameter, formed of about a dozen peu- 

 tagonal cells growing very gradually smaller toAvard the centre, the average of the cells 

 being .OOH mm. in diameter. Color delicate yellowish green, ribs pellucid. Height 

 of egir. .5S mm. : bn-adth. .53 mm. 



Caterpillar. First stayp. Head (78:52) black; body vinous broAvn, with a yellow 

 tinge, blotched tran.sversely with livid. Legs brown, prolegs the color of the l)ody. 

 Hairs strongly curved, blackish, situated on pa)>illae scarcely higher than broad, rather 

 shorter than the Avidth of the body at maturity. Length, 2,."j mm. ; breadth. ,3 mm. ; 

 breadth of head, .4 ram, 



iSevottd stage. Head (78 : 53) piceous with l>lack hairs : body dark broAvnish fuscous.
