Aspidiotfs S. STR. 
A. nerii Bouche must be regarded as the type. It will be observed 
that the scale is light colored and the exuviae are not covered by 
secretion. The terminal lobes of the female are wide apart, and the 
plates (or glandular hairs) are well developed and strongly fringed. 
There are no deep depressions between the lobes, and the chitinous 
processes at their bases are 
[r^C^k^^ki absent. The dorsal glands 
are very well developed (see 
fig.O, A. ])i<t< <triiis) and in form 
and position differ from those 
of other sections of Aspidiotus. 
It will be noticed at the out- 
set that in the fringe, and es- 
pecially in the dorsal glands, 
there is indicated some rela- 
tionship to those remarkable 
genera, Parlatoria, Synycnas- 
pis, and Leucaspis. These 
three genera are exclusively 
natives of the Old World, tlie 
recent determination of Parlatoria pergandii from China and Japan 
(specimens quarantined by Mr. Craw) showing that the one apparently 
American species, if regarded as valid, is of foreign origin. This toler- 
ably obvious affinity would of itself indicate that Aspidiotus s. str. 
belonged to the Old World; and a careful survey of the genus reveals 
the fact that there is no good reason for supposing that any species of 
this subgenus is a native of 
America. A. destructor, so 
common in the West Indies, 
is unquestionably a native of 
the eastern tropics, whence it 
was originally described. A. 
ohirtis, a modified form of this 
subgenus, might be thought 
surely native of America, 
being found in Xew York and 
Georgia, but it proves to be a 
well-known species of Central 
Europe; and against the 
probability of its being a native of both continents is the fact that it 
does not occur in the coniferous forests of the West, as does the really 
native Chionaspis pinifolii. It can not be doubted, I think, that A. 
abietis (inch pini) is an introduction from Europe. 
There are two peculiar West Indian species which represent a modi- 
fied type of Aspidiotus s. str., viz: A. sacchari and A. hartii. The
