antenne on the ventral surface are from 5 to 10 minute spinous tubercles. 
Parastigmatic glands not present. Stigmata subcylindrical. Pygidium (PI. VI, 
fig. 6) with 6 lobes, median pair shorter than the next, weakly tricuspid, light- 
brown, next pair bicuspid, slightly paler, exterior pair of the same color, bicuspid, 
of the same length as the median. Chitinous portions of all lobes run anteriorly 
for some distance into the pygidial area, the surface of which is closely, longi- 
tudinally striate. Squames as follows for each side: 2, apically fimbriated, 
between the median lobes, similar ones, but more slender, between Ist and 2d 
lobes, 3 stouter between 2d and 3d lobes, with fimbriation somewhat externally 
laterad of apex; a series of 9 broad, laterally fimbriated ones beyond the 3d lobe 
and extending one-third the distance from the latter to the base of pygidial 
margin. These squames decrease in length and increase in width from the third 
lobe and the number and length of their fimbriations decrease so that the last one 
bears but 1 prominent spine, the remainder being reduced to sharp serrations of 
its latero-apical margin. Set placed as follows: One pair at the external base 
of each median lobe nearly twice the length of latter, 1 pair between the second 
lobe and its Ist external squame, 1 pair ventrad to external lobe, 1 very short, 
ventrad to the 4th of the exterior 9 squames, 1. ventrad to the last squame, a small 
setose tubercle near the ventral margin, two-thirds of the distance from the last 
squame to the base of the pygidium. Four groups of circumgenital glands, the 
posterior pair with 4 to 6 orifices, the anterior with 7 to 12. Tubular spinnerets 
filiform; their heads chitinous; tube obconical, chitinous; their tongues one-third 
the diameter of their heads and equal to them in length. Numerous trumpet- 
shaped or subcylindrical ducts toward the apex and having orifices on the margin, 
as do tubular spinnerets. Anal opening about halfway from genital orifice to 
posterior apex. For details of structure see Plate VII, fig. 6. ~ 
Adult male (P1. VII, fig. 1).—Pale-yellow, with darker, pinkish-yellow, trans- 
verse apodema. Head about one-tenth the length of entire body, including genital 
sheath. Ocelli very dark red; upper pair slightly extra-marginal, lower pair 
posterior and contiguous on median line, their diameter one-fourth greater than 
upper ocelli. True eyes posterior to and their own diameter distant from the 
upper ocelli, submarginal. Antenne composed of 10 joints, of which the first 2 are 
subglobular, 3 to 5 subequal in length and about 3 times the length of second, 
all segments sparsely setose. Tenth segment attenuated, terminating in a clubbed 
hair, surrounded by 3 other curved hairs of equal length. This is shown by 
Plate VII, fig. 7. Legs moderately long, posterior femora slightly stouter than 
the others. The single jointed tarsi, two-thirds the length of tibie, slender, 
subconical and moderately covered with spinous hairs. Tibia subequal to femora, 
with a very few hairs each. Claws or ungues one-fourth the length of tarsi, 
their digitules two-thirds their length. Tarsal digitule as long as ungues. 
Genital sheath long and tapering to a sharp point; two-sevenths of the length of 
the rest of the body. Wings iridescent, hyaline, obovate; veins of about equal 
length and subparallel to the respective margins. Haltere has the first joint 
swollen to about one-third its length, just before the apex. Second joint of 
length equal to the first; spinous and hooked at extremity. Length of wing 0.63 
millimeter. This insect so nearly resembles Aspidiotus latanie Sign. that it is 
very difficult to separate the two species. The chief points of difference in the 
female are the number of squames external to the outer lobe, the number of orifices 
in the cireumgenital glands, and the relative length of the median and second lobes 
of the pygidium, the median in A. destructor Sign., being shorter than the 2d 
pair, while in A. latanie Sign., they are of equal length and more markedly 
tricuspid.
