EGG. Length, .25 mm. Ellipsoidal in form ; purplish in color. 



LARVA. Length, .3 mm. Oval in outline, broadest anteriorly 

 and red in color. 



SCALE OF FEMALE. Plate 2, Figs. 4 and 4 B. Length, 3 4 mm. 

 Usually nearly parallel-sided, as in Mytilaspis, but occasionally broad- 

 ened posteriorly, as in other species of Chionaspis. Strongly con- 

 vex ; moderately thick in texture ; snow-white in color often with a 

 glossy surface. Exuviae i mm. long. First exuvia nearly colorless ; 

 second, generally bright orange but occasionally dull yellowish-brown. 



FEMALE. Plate 7, Fig. 8. Lobes thin, almost transparent, striate, 

 entire ; all well developed. Median lobes separated by a distance 

 equal to about one-third the width of a lobe. Second and third 

 pairs with the inner lobule larger. The gland-spines are arranged as 

 follows: i, i, i, i, 1-2, 1-3. Moderately long, those nearest the 

 median lobes and those in the fifth group being shortest. Both 

 spines near the median lobes short and small, and other dorsal ones 

 quite long. Second row of dorsal gland-orifices represented only by 

 the anterior group consisting of 2 4 orifices. Third row with 4 5 

 orifices in the anterior and 4 6 in the posterior group. Fourth row 

 with 3 7 orifices in the anterior and 6 10 in the posterior group. 

 Median group of eircumgcnital gland-orifices, 7 13 ; anterior laterals, 

 12 21 ; posterior laterals, 14 19.
