Deserilied from 2 cf 2?. 



Andioconia (46 :2). Taperin"; to the middle, then for a brief distance e((nal and then 

 taperinji' aiiain like a sharpened pencil point to the apical thread, which is not more 

 than one fourth of the whole: apical tlireadlets expandintf. Total leni^th. .4 mm. ; 

 basal breadth, .u;'>2 mm. 



Egg (64:2). Short and stout, barrel-shaped, the top domed, the l)ase broadly 

 rounded : lariicst in the middle and about one-fifth higher than brf)ad ; sides with al)out 

 eisjjhteeu vertical ridijesand furrows having a very zigzag course, the former pinched at 

 tlie summit and buttressed at every angle by the thickened ends of cross lines, which 

 scarcely extend half way across the interspaces and do not meet those of the next 

 vertical ridge, but interdigitate witli them ; several of the ribs unite or die out as the 

 egg begins to narrow above, or even before that. Color yellowish white when laid 

 (Braun) ; afterwards the interspaces are dull plumbeous yellow, the cross lines, and 

 summits of the vertical ridges silvery white. The micropyle rosette is a tracery of 

 delicately margined irregular polygonal cells, growing slightly smaller toward the cen- 

 tre, the whole covering an area about .2 mm. in diameter, and appearing to overlie a 

 thick, silvery Avhite, chitinous mass (the common meeting ground of the vertical ribs), 

 excepting for a clear central space .05 mm. in diameter, in which about eight kite- 

 shaped minute cells distinctly radiate around a common centre, surrounded by a single 

 roAv of the outer rosette ; the largest of the outer cells of the rosette has a diameter 

 of about 0.025 mm. Height of egg, 1.25 mm. ; width, 1.1 mm. 



Caterpillar. First stage. (70:2; 74:11). Head (78 :l-4) obscure pale green, coarsely 

 punctate, the punctae slightly infuscated at the bottom, ranged very regulai'ly in 

 obli(|ue rows .03 mm. apart, each Avith an inconspicuous pointed hair, Avhich scarcely 

 rises above the level of the puncture, but is occasionally larger, or about .04 mm. in 

 length ; besides there are a few definitely arranged, stout, blunt, curving, pellucid 

 hairs about .03 in length, arising from brown dots, viz., on either side three in a hori- 

 zontal line midway up the face, of which the two inner are close together next the 

 summit of the frontal triangle, and the outer forms the lowest of a vertical series of 

 three ; between the middle ones of the two series but nearer the upper is another ; and 

 there are others below all. Ocelli black; mouth parts of the color of the head, 

 the mandibles slightly testaceous. Body largest at anterior extremity and tapering back- 

 ward slightly, but on the final segments more rapidly; terminal segment terminating 

 on either side in a 'oluntly conical point bearing a papilla and hair. Color pallid be- 

 neath, plumbeous above, with a lirownish fuscous dorsal stripe, a moderately narrow 

 sui^ralateral line and a broad stigmatal band ; papillae hemispherical ; stigmata black- 

 ish fuscous; legs very pale brownish. Length 2.3 mm. at birth. 



Second stage (87:17). Head very pale greenish brown with a pair of very faint 

 equidistant vertical stripes on either side; ocelli black; mouth parts, excepting the 

 dai'k testaceous edge of the mandibles, of the color of the head. Body above greenish 

 gray, tinged with bluish green on the thoracic segments, especially in front; a dorsal 

 stripe, dark bluish green in front, changing posteriorly through greenish brown to pale 

 reddish brown, edged thi-onghout finely and faintly with white: a suprastigmatal pale 

 reddish brown threatl ; a broad greenish brown laterostigmatal band, more greenish in 

 front, more reddish behind : an eipially broad, cloudy and faint, dull greenish stigmatal 

 band: the substigmatal fold dull yellowish: a ventrostigmatal jiale brown band, and
