 edge of either side of tlie penultlinnte segment is produced into a very thin delicate and 

 transparent lamina, prominent, regularly rounded and interiorly concave opposite the 

 coronet of bristles, and although very delicate appears to serve as a guard to them.

Described from 5<J , 2 9 . 



VariationB. Mr. W. D. Denton has shown me a specimen in which other than the 

 uppermost of the extra-mesial row of orange spots of the under surface show upon the 

 upper surface, viz., the spots in the upper subcostal interspace and in the medio- 

 submedian interspace. These are by no means so large nor so pure as below, and still 

 less distinct and much smaller is a long oval orange spot at the Isase of the second sub- 

 costal interspace. 



Mr. E. M. llulbert has a specimen in which the normally orange lunule next the costal 

 edge of the upper surface of the hind wings has no orange in it, but is of the same 

 greenish color as the other spots. 



Strecker describes a partially suffused specimen, preserved in Peale's collection, 

 having "the submarginal lunules of secondaries prolonged inwardly towards base, 

 forming dashes or rays " ; and also a highly interesting aberration as seen in a speci- 

 men in his own collection "with, on under surface of hind wings, a narrow yellow band 

 which crosses the wing nearly parallel with abdominal margin, running from near anal 

 angle to costa a short distance from base, the same as is always found in palamedes." 

 (Syn. cat. macrolep., 72.) 



Egg (66 : 13). With an exceedingly delicate tracery, within which tlie floor is nearly 

 smooth and a little glistening. The cells of the micropyle (68 : 20) nearly circular, are 

 very minute, not over .004 mm. in diameter, and the micropylic canals, to the number 

 of about twenty, are clustered into a space not over .02 mm. in diameter; color very 

 pale green when laid ; afterwards they become transparent white, and subsequently 

 spots of a darker green appear on the upper surface. Height, 1 mm. ; breadth in 

 middle, 1.3 mm. 



Caterpillar. First stage (72 : S). Head (79 : 69) blackish brown above in two large 

 coalesced oval spots which extend down cither side of the frontal triangle half way 

 to the base; rest of head, excepting the hind margin and ocelli which are blackish, 

 pale greenish; labrum and antennae pale; hairs black. Sides of the body either pale 

 plmnbcous or dark brownish fuscous ; dorsum either pale or variegated with brownish 

 fuscous and yellowish brown, the darker colors being more conspicuous on the first to 

 third and fifth to seventh abdominal segments, and the lighter tints more decided away 

 from the middle; the first thoracic segment brownish fuscous, lateral tubercles of first 

 thoracic segment brownish yellow or pale luteous; the fleshy warts of the supralateral 

 series are Inteous on the second, third and eighth abdominal segments, dusky on the 

 others; sometimes all are pale; first segment bears a pair of subdorsal white spots ; all 

 the hairs are black, those of the lateral and supralateral rows tipped with white. Legs 

 blackish ; prologs dusky ; osmateria pale orange. In a few days they become entirely 

 mottled with fuscous and yellowish brown, sometimes one and sometimes the other 

 being in excess. Length, 2.6-3.75 ram. ; breadth anteriorly,. 75 mm. ; posteriorly, .5 mm. 

 When full grown the length is 5.5 mm. ; breadth of head, .75 mm. ; greatest breadth 

 of body, 1.5 mm. ; at posterior extremity, .9 mm. 



Second stage (72 : 9). Head (79 : 70) as in the next stage. Body tumid in the ante-
