XXXIV, fig. 4). Dorsum armed with four pairs of very long spines, 
one pair on cephalic portion, one pair inserted before the vasiform 
orifice, and two pairs near the caudal margin. Yasiform orifice 
elliptical and transverse. Operculum of the shape indicated in Plate 
XXXI V, figure 3, its greatest width being 0.03 mm. The exposed 
portion of the lingula is short, setose, and armed^with two pairs of 
spines. 
Adult male. — The type slides of this species are dissections and of 
the adults only the wings and claspers are represented. The fore- 
wing (PI. XXXIV, fig. 6) is 0.68 mm. long and 0.24 mm. wide, and 
is of almost an equal width throughout. The radial sector only is 
present, and it is irregularly thickened. Maskell figures another vein 
in the wing, but in the types it does not exist and the wing is also of 
a different form from other species in Aleyrodes. The costal margin 
is armed with curved teeth on which are small hairs (PL. XXXIV, 
fig. T). The claspers (PL XXXIV, fig. 8) are unique. They are 
short, thick, hairy, and psy 11 id-like. The penis is almost equal in 
length to the claspers and slightly curved.
