ever greatly to be feared. The following discussion of the species is 

 found in the Report of the Commissioner of Agriculture for 1880, p. 293: 

 ''Scaleof Female. - This scale resem bles that of Axp idiot m liens in shape, 

 size, and the presence of the nipple-like prominence, which indicates 

 the position of the first Jarval skin ; but it can be readily distinguished 

 from the scale of that species as follows: It is light gray, and quite 

 translucent; its apparent color depending on the color of the insect be-

 dark, and usually darker than the remainder of the scale; and when 

 the female is fully grown the peculiar reniform body is discernible 

 through the scale, causing the darker part of the outer two-thirds of 

 the scale to appear as a broken ring. (Fig. &b.) * * *

"Eyy. I have not seen the eggs of this species, excepting those taken 

 from the body of the female. And as I have repeatedly found young 

 larvae under the scalts I am led to believe that the species is vivipar- 

 ous. 



u Scale of Male. The scale of the male resembles that of the female, 

 excepting that it is only one-fourth as large ; the posterior side is pro- 

 longed into a flap, which is quite thin; and the part which covers the 

 larval skin is often lighter than the remainder of the scale. 



"Male. The male is light yellow, with the thoracic baud brown, and
