Aspidiotus parniciosus Comst. Plate IV. Fig. i8: Plate V, Figs. ig. 20, 
21, 22, 23. 
The variations in the anal plate of female are greater than in 
any of the specimens of any species studied. In fact it was the 
exception to find one specimen having the structure of the two 
sides identical. The relative size of the chitinous processes be- 
tween the first and second lobe remained the same, “close together 
and of nearly equal size,” but these rarely ever appeared under the 
microscope at same focal point — tliat is, the relative sizes of the 
two could be gained only by focusing up and down. Dorsal 
glands uniformly few in number, small plate just laterad of second 
incision always present. 
A large number of individual mounts have been studied and 
sketches of many made to illustrate their structures. 
The scales of this group are uniformly dark, in many cases black, 
the white secretion covering the exuvise of male is scant, in some 
cases almost wanting, leaving the black sculptured ring and dot, 
resembling description of A. andromclas. Others, however, have 
the dot and ring fairly well marked. 
The anal plate of female has presented many interesting fea- 
tures. Fig. I may be considered as an extreme. N'cry few indeed 
show the forks in plates so marked as they appear at a. This 
figure farther shows two plates caudad first incision, serrate, in 
this the specimen is normal. The irregular!)' shaped plates pres- 
ent on left side at b, between spines four and five, and absent 
entirely on right has been frequently observed. This figure further 
shows the inconspicuous plates between the median lobes. Their 
absence in some specimens examined could be satisfactorily ex- 
plained by their being broken in course of preparation. 
Fig. II may be taken as an average, shows only one plate caudad 
of first incision and this plate forked. 
Laterad of spine four is another spine; this is unusual. Between 
spines four and five (not counting incidental spine) are two irreg- 
ular plates on right and three on left. 
Fig. Ill represents a left side of one specimen and a right side of 
another transposed and placed beneath for illustration of variations 
in structure of the two sides. 
Figs. IV and V represent other individuals studied. 
Newly born nymph. This agrees with description given by 
Howard and Marlatt in every respect save one. Their description 
reads: “The large central plates each terminate in a long hair.” 
In the twenty nymphs examined the long hairs are not connected
