develop the scales which cover them, they can be distinguished at 
a glance by the characteristic differences in their respective scales 
which we have described above. The female never afterwards 
leaves the scale, but attaches herself to the surface, on which she 
rests by means of a slender, hair-like proboscis or sucker, which 
we have particularly described in a former article when speaking 
of the Apple-tree species. She increases in size in proportion as 
she enlarges her protecting shield, and presents the appearance of 
a soft, wrinkled, footless, and apparently almost lifeless grub. 
She, however, fulfills, infallibly, it she be not interrupted, the few 
but paramount laws of her being, attains her normal development, 
in due time becomes impregnated, and shortly after deposits her 
eggs and perishes. With such unerring certainty does nature con¬ 
duct hei operations, in her lower walks, where she reigns supreme. 
Fixed immovable to the surface on which she reposes, and hid¬ 
den from view beneath the shadow of her vaulted carapace, but 
dimly conscious, we may presume, of some unfilled requirement 
of her being, the helpless female Coccus awaits the addresses of 
her unknown and invisible paramour. Nor does she wait in vain. 
Of all the countless myriads of these lowly creatures which congre¬ 
gate upon the bark of the apple tree, or whiten with their spotless 
phylacteries the foliage of the pine, not one, so far as we know, 
fails to be called to enact the offices of maternity. Nature, in the 
universality of her providence, takes them in her charge and min¬ 
isters to their necessities, and no unloved or unfruitful virgin is 
permitted to languish in the halls of the Coccidoe . 
At the same time that I was making my observations upon this 
insect, my friend, Mr. C. V. Riley of St. Louis, succeeded also in 
obtaining the perfected and hitherto unknown male of this species. 
The engraving at the head of this article, is the one prepared by 
Mr. Riley from his specimens, with a copy of which he had the 
kindness to furnish me. 
The following is a description of the male of this species. 
Length, one quarter of a line, or about one fiftieth of an inch. Color, pale red. 
Antennas as long as the body, ten jointed, counting as two the stout, basal, indistinctly 
bi-articulated joint; the other joints elongate, somewhat equal, except the last which is 
a little more than half as long as the preceding, each joint with a number of bristles 
more than half its own length. Eyes prominent, black, with comparatively few facets. 
The three segments of the thorax well developed. Meso-thorax somewhat elevated above.
