to be extricated. The perfect male is nearly as minute as a 
point, but a powerful magnifier shows its body to bo divided 
into segments, and endued with all the important parts and 
functions of a living animal. 
To the unassisted eye, says Dalman, it appears only as 
a red atom, but it is furnished with a pair of long whitish 
wings, long antennae or horns, six legs with their respective 
joints, and two bristles terminating the tail. This minute 
insect perforates the middle of the case covering the female, 
and thus celebrates its nuptials with its invisible partner. 
The hitter subsequently deposits her eggs and dies. In due 
time the young are hatched and leave the case, under which 
they were fostered, by a little crevice at its hinder part. 
These young lice, which I have seen, are very small, of a 
pale yellowish brown color, and of an oval shape, very flat, 
and appearing like minute scales. They move about for a 
while, at length become stationary, increase in size, and in 
due time the whitish shells are produced, and the included 
insects pass from the larva to the pupa state. The means 
for destroying these insects are the same as those recom- 
mended for the exterminatioh of the previous species. 
Many years ago, when on a visit from home, I observed 
on a fine native grape-vine, that was trained against the 
side of a house, great numbers of reddish-brown bark-lice, 
of a globular form, and about half as large as a small pea, 
arranged in lines on the stems. An opportunity for further 
examination of this species did not occur till the summer of 
1839, when I was led to .the discovery of a few of these 
lice on my Isabella grape-vines, by seeing the ants ascending 
and descending the stems. Upon careful search I discov- 
ered the lice, which were nearly of the color of the bark 
of the vine, partly imbedded in a little crevice of the bark, 
and arranged one behind another in a line. They drew 
great quantities of sap, as was apparent by their exudations, 
by which the ants were attracted. Further observations 
were arrested by a fire which consumed the house and the 
vines that were trained to it.
