966 THE BUTTERFLIES OF NEW EXCLANU. 



sides parallel, similarly roumlcHl at tlie two oiuls, -with about ten to Iwi'lvc parallel rows 

 of connecteil, moderately large, l)ead-like dots, which do not extend \ipon the narrowing 

 base; pedicel slender and ecinal and not very long; lamina nearly .dOO mm. in breadth. 



Egg (65 : 12-13). Of a pale green color, the tracery of raised net work l)eing frost- 

 •white njion it. On the sides neij;hl)orin,;; triangular or wedge-shaped cells, which 

 average about .04 mm. in length, are often arranged around a common centre so as to 

 give it the effect of being .stamped witli a number of wheels, of which the irregular 

 centre is sometimes enlarged so much as to be .02 mm. in average diameter; the 

 average cell walls are here about .01 mm. thick. Above, the cell walls are of the same 

 thickness, but the average diameter of the cells is only about .025 mm. The average 

 micropyle cells are about .000 mm. in diameter with the tliinest possible walls ; the 

 central cells are only .007.5 mm. in diameter. The egg itself is .7 mm. in diameter and 

 half that height. 



Caterpillar. First stage (71: 4). Head (79: 32) greenish Uiluous; ocelli and 

 sntnres black; mouth parts pale green. Body pale green; papillae very dark green 

 ringed with black. Legs and prolegs of the color of the body. Hairs hoary, the 

 longer curving ones longer than the width of the body. Spiracles white encircled 

 with black. Length of body, 1.25 mm. ; of longest laterodorsal hairs, .4 mm. ; of 

 shortest in same series, .15 mm. 



Third stage {15: Z6). Head (79 : 3,3) dark olive fuliginous. Body pea-green with a 

 narrow, dorsal, darker green line, margined by a pale stripe following the edge of the 

 narrow, dorsal Held and ending with the seventh abdominal segment. Hairs brown. 

 Papillae and anunli blackish, giving a grisly appearance to the body. Spiracles black- 

 ish. Length, 4 mm. 



Fourth stage {IB -.M). Differs from the preceding only in that a faint, infra.stig- 

 matal, pale line follows the substigmatal fold ; and on the sloping sides numerous 

 slender, faint, oblique, paler lines ruu from above downward and back^vard at an angle 

 of 45° with the lower margin, each line covering three segments and interrupted at the 

 incisures, the middle segments having parts of four distinct stripes on them. Length, 

 7 ram. 



Last stage (75:38). Head (79:35) piceons; month parts fnsco-luteous. Body 

 pale pea-green, a little hoary from tlie delicate pale brown pile, arising from rather 

 sparsely and irregularly scattered, dot-like papillae, black and white in about equal 

 proportion. Dorsal field darker green, especially on the anterior half of the segments, 

 through the readily seen pulsations of the dorsal vessel ; the subdorsal ridges pale 

 yellowish and the substigmatal fold white or livid aud continuous, a little fainter on 

 the thoracic segment and dying out just before the hinder edge of the last; declivent 

 sides with very faint, pale, oblique stripes as in preceding stage. Spiracles pale with 

 a faint, tine, fuscous annnlus; tirst thoracic segment slightly dulled in color with a 

 central, transverse, roundish, plumbeous-green, rhomboidal shield. Legs p.ale testaceous 

 with testaceous claws. Prolegs greon. Length, 12.25 mm. ; breadth, 3.25 mm. ; 

 height, 2.5 mm. 



ChrysaliE (84:41). Pea-green, the head barely paler, the al)domeu tinged with 

 yellow excepting along the dorsal line, which is grass-green except posteriorly. The 

 integument is exceptionally translucent, permitting the fatty bodies, the traclieae and 

 the veins of both upper aud under wings to be readily seen. No markings whatever. 

 Surface of body covered with a delicate tracery, forming a broken, irregular reticulation 

 of raised Hues, next and between which the surface is very delicately wrinkled^ 

 everywhere encircling the papillae which never touch them. Spiracles pallid. The 

 sparsely scattered, short, fine, hyaline hairs (86 : 15, IG) arising from fulvous papillae 

 giving a slight tint to the prothorax where they are most abundant, and where the 

 hairs are of two sorts, a longer, straight and slender, terminating in a bunch of 

 bristles (86: Hi), the whole length of which, exclusive of the papilla, is .1 mm. and 

 found only on the Sides of the prothorax ; aud a shorter, rather stouter and simple, some- 

 times slightly curved hair (86: 15), .06 mm. long; the latter only are found on other 

 parts of the body. Hooklets of cremaster reddish. The girth passes between the first
