 (Figure 2(18, D-I) 



Egg — Size 0.16 by 0.9!) nun. Elliptical in form; stalk very short; jjointed at 

 distal end. Pale yellow in color with dark brown stalk. 



Pupa case — Size about I.l b}' 0.88 mm. Broadly oval in form, broadest 

 about the middle. Color under hand lens, shining black; under microscope, the 

 color is brown, with sutures dark brown. Mature specimens moderately convex. 

 There is a very short and squarely trimmed marginal fringe all round from the 

 lateral wax tubes, extending out flat on the surface of leaf. Dorsum of case is 

 much corrugated, keeled for entire length. The thoraco-abdominal suture is 

 sinuate and extends to the marginal rim, somewhat wider on the sides. This 

 rim is plainly demarked from dorsum by a thickened line all around. The margin 

 is crenulated, the incisions quite uniform and acute. On cephalic end of case 

 the transparent, subreniform "eye spots" are very distinct. 



Vasiform orifice elongate cordate ; about three-fourths as broad as long, 

 cephalic margin nearly straight, caudal end bluntly rounded; operculum subellip- 

 tical, cephalic margin straight, about one-third as long as orifice ; lingula usual, 

 broad, extending quite to caudal end of orifice. 



Adult female — Length about 1.2 mm.; forewing 1.1 by O.til nun., hind tibia 

 0.41 mm., hind tarsus 0.20 mm. Color of body, uniformly pale yellow, except 

 the frons, which is deep brownish ; antenna- and legs pale ; eyes red, constricted in 

 the middle ; forewings marked with two irregular broken bands of orange red- 

 each crossing wing about equidistant on each side of caudal flexure of vine. There 

 is also a small central spot, almost caudad of flexure. A small, irregular spot 

 also occurs caudad of veinlet, near base of wing. 



Adult male — Very like female, but small. Genitalia rather slender, slightly 

 curved at tip and acute.
