Genus ALEURODICUS Douglas. 
With the general characters of the family, but differing from 
Aleurodes in having the vein in both pairs of wings with a distal and 
basal branch. 
TABLE OF SPECIES OF ALEURODICUS. ! 
Wings of adults immaculate. 
Q—Length 2.1 mm.; wing expanse 4.1 mm.; length hind tibia 0.78 mm. ; 
length hind tarsus 0.36 mm.; dull honey yellow with eyes darker. Joint 
3 of antennze as long as the three distal joints together, and twice as 
long as joints 1 and 2 together. Pupa-case secreting an abundance of 
white wax and very long glassy filaments, ovate, or very broadly ellipti- 
cal; compound pores smaller than in anonx; operculum but moderately 
concaye on caudal margin; lingula broad, tapering to rounded end; not

Similar to preceding, but larger. Length of fore-wing 3 mm; length hind 
tibia 0.96 mm.; length hind tarsus 0.47 mm. Pupa-case more nearly 
elliptical and the compound pores larger than in cocois; operculum on 
caudal margin suddenly indented and then straight; lingula compara- 
tively narrow, notched distally, and tapering to rather acute point. 
anone Morgan (1) 
Wings with a dark spot in angle of distal bifurcation of vein. 
Head, thorax, and abdomen pale yellowish white. The dark spot of fore- 
wings,.an obtuse angle, opening distally. Posterior wings with similar 
but fainter spot. Eyes brown, two-parted. Tarsi long, exceeding two- 
thirds length of tibia. Pupa-case secreting a white downy wax. 
asarumis Shimer (2) 
Similar to asarumis, but with body and legs of deep chrome yellow; eyes not 
divided, but dumb-bell shape. Fore-wing 2 mm., noticeably iridescent; 
spot on fore-wings of rather indistinct outline, and extending cephalad 
to margin of wing as a very dilute clouding. Hind-wings unspotted. 
Pupa-case dark gray or plumbeous, varying to brownish, surrounded by 
abundant cottony secretion; along midrib of leaf, as in pulvinata; oper- 
culum very broad, broadly truncate distally; lingula spatulate, tapering

¢ —Both pairs of wings with a distinct brownish-black spot; fore-wings with 
an ill-defined clouding all around margin, appearing centrally as an 
oblique, very obscure band. Length 0.86 mm.; fore-wing 1.1 by 0.52 
mm. Eyes reddish, not divided. Genitalia very much reduced, valves 
short and stubby. Pupa-case subelliptical; cephalic and caudal pairs of 
compound pores largest; operculum well rounded on caudal margin; 
lingula spatulate, gradually tapering to somewhat rounded point. 
minima n. sp. (7) 
Wings variously spotted or banded with gray or blackish. 
Wings with more or less rounded spots. 
Color bright yellow, legs and antenn paler. Length, 1.23 mm.; length fore- 
wing, 2.4mm.; with submarginal series of blackish spots, and more circular 
1 Aleurodicus (Alewrodes) pulvinata Maskell is not indicated in the table, and is 
referred to Aleurodicus on the authority of Cockerell (Psyche, v. 8, No. 266, p. 226). 
If a description of the adult stage of this species has been made, I have not been able 
to find it.
