TABLE OF THE AMERICAN SPECIES OF ALEURODES. 
I. Pupa-case usually but little hidden by secretion; with lateral fringe—. e., any 
secretion from marginal wax tubes. 
II. Pupa-case usually hidden by a mass of hairy, waxy or floeculent secretion. 
III. Pupa-case evident, and without lateral fringe. 
I. Pupa-case usually but little hidden by secretion; with lateral fringe—i. e., any secre- 
tion from the marginal wax tubes. 
Pupa-case uniformly brown or black. 
With dorsal secretion of wax. Dorsal secretion cottony or mealy in 
appearance. 
Pupa-case dark brown to black, elliptical, slightly convex, about 
0.85 mm. long. Dorsum covered with white meal, frequently 
becoming quite solid. Lateral fringe, all around, agglomerated 
almost into a solid plate, of unequal length, giving a star shape of 
about 8 rays. Operculum subcircular, covering about one-half of 
orifice; lingula obsolete: 2252-6 scenes aaa stellata 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, nearly 
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. 
fumipennis Hempel (18.) 
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. 
acaciz n. sp. (3.) 
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 
mealy secretion may occur on dorsum; with tube-like Jongitudinal 
medio-dorsal elevation, cephalad, arrow-shaped; along abdominal 
segments, suggesting a trachea, with a glottis caudad. 
tracheifer n. sp. (38.) 
Pupa-case shiny black, flat, subovate; 0.95 by 0.81 mm.; cephalo- 
lateral margins on each side with an indenture and thickening. 
Lateral fringe semitransparent; a very light mealy secretion of 
wax may occur along body segments. Dorsum with small black

Without dorsal secretion of wax. 
Lateral fringe gelatinous looking (translucent) . 
Pupa-case pitch black, oval, hardly one millimeter long. The gela- 
tinous fringe extending out from case, rather more than one-half 
width of case, and raising it up somewhat. From cephalo-lateral 
margin on each side and from caudal end a pencil of white wax 
resting on gelatinous rim..........--.-.--.-- gelatinosus Ckll. (19)

Lateral fringe a series of distinct radiating waxy ribbons. 
Pupa-case intense black, oval, hardly over a millimeter long. The 
lateral fringe of 12 broad ribbon-like rays of glassy wax, yellow 
basally, about as long as length of case..... vinsonioides Ckll, (41)
