jecting mostly beyond the margin. Wings of adults immac- 

 ulate; eyes large, black, bean-shaped filJcium (13). 



The lateral fringe consisting of but three curling, white waxen 

 filaments, from long, thickened tubular pores, opening one on 

 each side in cephalolateral region and one at caudal end of case. 

 Pupa-case pale greenish yellow to yellowish, broadly oval, but 

 little convex, applied close to leaf, and inconspicuous; 1.4 

 by 0.8 to 1 mm. ; margin minutely crenulated and with radi- 

 ating lines extending mesad. Vasiform orifice small, sub- 

 circular, operculum short, concave distal! y. Adults with 



immaculate wings dtri (8). 



The lateral fringe transparent, white rods of variable length; when 

 short, so deflexed as to appear vertical. 



Pupa-case pale yellow, elliptical, caudal, and truncate; 0.9 by 

 0. 65 mm. ; marginal rim wide, demarked from dorsum by a 

 thick line. Vertical fringe common to this type of Aleurodes, 



absent masMU (44). 



The lateral fringe of separate, glassy rods, or of glassy, agglomerate 

 rods covered more or less with flocculent wax. 



Pupa-case yellow, elliptical, 1.4 by 0.8 mm., raised on a vertical 

 fringe; dorsum witli 12 pairs of conspicuous spines. 



diasemua (38). 

 The lateral fringe very narrow, of white agglomerate rods, ragged 

 distal] y. 



Pupa-case yellow, when empty, a white, transparent film; 

 elliptical, 0.9 by 0.8 mm.; dorsum with 5 pairs of sjnnes. 

 Lateral secretion may be fragmentary, or so short and 



deflexed that it similates a vertical fringe e.rtranlcns (46). 



II. Pupa-case usually hidden l)y a mass of hairy, waxy, or flocculent secretion. 

 The secretion white, felt-like, or hairy. 



Pupa-case black, oval, 0.94 mm. long. Flat, but dorsum with 

 median ridge, and several transverse furrows. Margin with 

 double crenulation. Vasiform orifice and operculum hemi- 

 spherical; operculum small, not filling orifice. Wings of 



adults immaculate parvus (27). 



Larva yellowish green, somewhat roundish, 0.5 mm. long. 

 Margin witli double crenulations which are pointed distally. 

 Ventral surface with five pairs of bristles along middle line, 

 about as long as one-third width of body. Pupa-case with 



10 to 12 long radiating wax threads, star-like goijah.r (20). 



Larva similar to gotjahsc, but only the caudal pair of bristles 

 readily discernable. Pupa-case scantly covered with the 

 unequal curling waxen threads. A submarginal series of 



equally placed short bristles aepim (4). 



Pupa-case covered with a mass of wool-like wax often more than 

 twice its length. Case yellow, elliptical, 1 liy 0.6 mm., 

 raised on a short, vertical fringe; dorsum convex, covered 



with conspicuous papillae merlini (31 ). 



The secretion yellowish, long, hair-like. 



Pupa-case light yellow, elliptical, 1 mm. long, flat. Denuded 

 of the yellowish hair-like secretion, a longitudinal median, 

 and submarginal secretion on each side of white wax is evi- 

 dent. Vasiform orifice subelliptical. Operculum hemi- 

 spherical, n rly fitting orifice, the caudal end notched. 

 Adult with wings immaculate, eyes black Jiorridus (22).
