TABLE OF THE AMERICAN SPECIES OF ALEURODES. 
I. Pupa-case usually but little hidden by secretion; with lateral fringe— i. e., any 
secretion from marginal wax tubes. 
II. Pupa-case usually hidden by a mass of hairy, waxy or flocculent secretion. 
HI. Papa-case evident, and without lateral fringe. 
I. Pupa-case usually but little hidden by secretion; with lateral fringe—?, e. anv secre- 
tion from the marginal wax tubes. ' - 
Pupa -case uniformly brown or black. 
With dorsal secretion of wax. Dorsal secretion cottony or mealv in 
appearance. 
Pupa-case dark brown to black, elliptical, slightlv convex, about 
0.85 mm. long. Dorsum covered with white meal, frequently 
becoming quite solid. Lateral fringe, all around, agglomerated 
a most into a solid plate, of unequal length, giving a star shape of 
about 8 rays. Operculum subcircular, covering about one-half of 
orifice; hngula obsolete stellaia Mask. (37.) 
Pupa-case black, elliptical, convex, 1.8 mm. long. Margin thick 
with conspicuous groove on dorsal surface, and short fringe of 
wax on ventral surface. Around vasiform orifice, a large, nearlv 
transparent, hemispherical area, but dusted with white secretion 
Around lateral margin, a row of about 32 sharp sword-like hairs' 
Adult 9 with basal half and portions of rest' of wing smoky.

Pupa-case shiny black; size about 0.92 by 0.61 mm.; subelliptical 
moderately convex; lateral fringe rather short, truncate; dorsal 
secretion of 3 longitudinal stripes of cottony or mealy wax.

Pupa-case .dull black; subelliptical; 0.81 by 0.52 mm.; the copious 
lateral fringe, about twice the width of case in length. A slight 
»H*aly secretion may occur on dorsum; with tube-like- longitudinal 
'n^o-dorsal elevation, cephalad, arrow-shaped; along aWominal 
segments, suggesting a trachea, with a glottis caudad.
