EGG. Slightly more than .2 mm. long; ellipsoidal, reddish-purple. 

 Miss Ormerod states that the color of the eggs is crimson, but it 

 seems probable that the specimens she had for examination were 

 about to hatch in which case they would be more reddish in color than 

 those in which the embryos had not developed. I have seen only 

 newly laid specimens. 



SCALE OF FEMALE. Plate 2, Fig. 8. Length, 2.2 2.8 mm. 

 Decidedly broadened posteriorly ; moderately strong in texture ; snow 

 white or dirty white in color. Exuviae .8 .9 mm. long ; varying in 

 color from orange-yellow to brown or sometimes almost colorless. 



FEMALE. According to Signoret the color of the body (Plate 5^ 

 Fig. 8), is reddish-yellow. Median lobes (Plate 7, Fig. i) about as 

 broad as long, obscurely striate, with edges somewhat triangular, 

 sometimes faintly serrate on the sides. Second and third lobes each 

 with the inner lobule much larger than the outer ; striate, sometimes 

 obscurely serrate on the outer edge. The gland-spines are arranged 

 as follows : i, 1-2, 1-2, 1-2, 3-7. The first one small, though readily 

 seen. When two occur together one is smaller and often directly 

 above the other. Second row of dorsal gland-orifices represented only 

 by the anterior group consisting of 2 6 orifices. Third row with. 

 4 9 orifices in the anterior and 5 9 in the posterior group. Fourth 

 row with 3 8 orifices in the anterior and 39 in the posterior group.* 

 Median group of circumgenital gland-orifices, n 17 ; anterior laterals, 

 26 44; posterior laterals, 18 29. 



SCALE OF MALE. Plate 2, Fig. 8 A. Length, .7 i mm. Of 

 definite outline, distinctly carinated. Exuvia pale yellow or colorless, 

 occupying one-third to one-half the length of the scale. 



MALE.! Elongated, flattened, red or sometimes yellowish ; apter- 

 ous or with wings. Antennae with third joint longest, fourth, fifth, 



Occasionally there are a few scattering gland-orifices precisely like those around the gen- 

 ital opening. These represent the second arch which has been the distinguishing character 

 of the genus Poliaspis. This genus is no longer retained. 



tThe description of the male is compiled from the writings of Bouche, Signoret and New- 

 stead. I have never seen specimens of this sex.
