726 The American Naturalist. [August, 
marked tendency to become more destructive than in their 
native habitat. 
If the naturalist, pure and simple, on reading these lines 
should say that the matter does not concern him, but the hor- 
ticulturist, he is begged to remember the bearing of these 
changes on questions of geographical distribution. If, ignor- 
ant of what is going on through man’s energy, he proceeds to 
collect Coccide and argue about their distribution, he will ar- 
rive at the most extraordinary conclusions, and will, perhaps, 
be asking for sunken continents to explain phenomena which 
had no existence twenty-five years ago! 
The notes given will be placed under sub-heads indicating 
the several countries, states or districts. Species marked * are 
new to the region indicated by the sub-head. This merely 
means that they are first found there, whether on wild or cul- 
tivated plants, out of doors or in hothouses. But native and 
introduced species will not be placed under the same sub-head 
if it can be avoided; when we do not know whether a species 
is native or not, it will be assumed for the present to be so.

While we have no positive information to guide us, I be- 
lieve the following species have been introduced. They were 
all coll. Mr. Barber, Superintendent of Agriculture of the Lee- 
ward Institute (cp. Ins. Life, VI, 50-51.) 
Aspidiotus destructor Signoret. On leaves of banana at Clare 
Hall; also on cocoanut, Jan. 15, 1895. 
Aspidiotus personatus Comst. A few on rose leaves, and 
many on Ficus sp. near benjamina (cp. Jn. Inst., J amaica, 1892, 
54). This isthe fifth Aspidiotus found on rose, the others being 
A. fiscus, A. articulatus, A. dictyospermi var. jamaicensis, and A.
