66 CLASSIFICATION OF THE ALEYRODnXSE. 
below the apex. On the upper half of the wing (i. e. above the central nervure) 
the bands are nearly straight and about equidistant, but they mostly enlarge 
about the middle of the wing, the third and fourth being joined by the inward 
prolongation of the longitudinal band. The third band is interrupted below its 
middle, and its lower part is joined to the second band, of which it appears an 
oblique branch. The true prolongation of the second band bends obliquely in- 
wards, and is joined at one point to the first band. The second band is also 
joined to the first by a thin process in the region of the central nervure. For 
the rest, the insect is white, with the abdomen slightly yellowish. The larva 
is grey, with white secretion. The antenna?, legs, venation, glands of larva, 
etc.. seem to be practically as in A. anoiue, and need not, therefore, be described. 
DESCRIPTIVE REMARKS. 
Pupa case. — Elliptical, about 1 mm. long by 0.84 mm. wide. Color 
under microscope yellow, darker centrally. Margin of case lightly 
crenulate. Dorsum lktle elevated, segments distinct (PL XXII, 
fig. 1). Just within margin of case all around is a series of wax 
pores, resembling somewhat in structure the compound wax pore, and 
secreting long slender wax rods (PI. XXII, fig. 4). On caudal mar- 
gin of case are two pairs of spines, and just within margin all around 
is a series of spines, the exact number of which can not be deter- 
mined on account of the imperfect condition of the single pupa case 
in the type material. There are four pairs of the usual compound 
wax pores on abdomen and a pair on cephalic end of case (PI. XXII, 
fig. 3). 
Vasiform orifice broader than long, subcordate; operculum short, 
twice as broad as long. Lingula protruded and very long (0.15 mm. 
from base to tip), spatulate, with two pairs of strong spines at caudal 
end. The unusually large lingula resembles that of dugesil, though 
it is not dark in color as in that species (PL XXII, fig. 2). 
Adult female. — Length of forewing about 2 mm.; width about 1 
mm. Body reddish brown. Eyes reniform, plumbeous. Length of 
fore tibia 0.4G mm. Length of fore tarsus 0.27 mm., the segments 
subequal in length. Wings banded with dusky, as shown in Plate 
XXII, figure 5, and about as described by Prof. Cockerell.

(1895). 
In the Maskell collection of Aleyrodidoe loaned to the Bureau of 
Entomology by the New Zealand Institute arc two examples of the 
pupa case of this species, in balsam slide mounts. This insect has in 
general the type of case of < <><<>'ts. hut presents distinctive < I i H'erenees. 
While originally described a- an Aleprodea by Maskell, its resem- 
blance in structure to Aleurodicus was recognized by the describer,
