task. The insect is now becoming more and more abundant, has 
established itself in Rhode Island and is gradually extending its 
range. The brown tail moth, Euproctis chrysorrhoea 
Linn., has also become established in that state, is known to oecur 
in New Hampshire and Maine and is rapidly extending its range. 
The elms of that commonwealth are seriously injured by the 
imported elm leaf beetle, Galerucella luteola Miill., which 
has made its way over a considerable proportion of the state 
and is being assisted in its destructive work by the imported elm 
bark louse, Gossyparia ulmi Geoff. It would seem as if 
this might be sufficient, but apparently not, since the dreaded 
San José scale, Aspidiotus perniciosus Comst., is also 
established in a number of localities in that state and is proving 
true to its reputation in other places. 
The condition of New York State is not. much happier than 
that of its sister commonwealth, though as yet it is free from 
the gipsy and brown tail moths. Our elms, however, are badly 
injured from year to year by both the elm leaf beetle and the 
elm bark louse, and the shade trees in the vicinity of New York 
city are seriously ravaged by another imported insect, the leopard 
moth, Zeuzera pyrina Linn., a species which thrives in a 
large number of trees and when not checked inflicts extensive in- 
juries. Our fruit trees are suffering here and there from exces- 
sive infestation by San José scale. The pear psylla, Psylla 
pyricola Forst., occasionally inflicts great injury on this fruit 
tree in various portions of the State. 
In the South, we find the cotton boll weevil, Anthonomus 
grandis Boh., threatening the cotton crop of Texas, while the 
harlequin cabbage bug, Murgantia histrionica Hahn., has 
established itself in numbers in most of the southern states and 
is proving an exceedingly serious enemy of cruciferous crops. 
The imported peach scale, Diaspis pentagona Targ., is 
another recent introduction which has become established in 
several localities in the southern states and bids fair to rival in 
destructiveness the San José scale. It is also established in one 
or two localities in the north. 
These are all insects which have been introduced into this 
eountry within comparatively recent years and which are proving 
pests of first importance. It is interesting in this connection to
