with the markings, as far as observable, of a pale yellow or yellow- 
ish-green. These were somewhat variable, but might be described 
as one central patch on the fore part of the thorax (or body between 
the wings), two patches or marks on the succeeding part, and 
narrow cross stripes on the abdomen. The eyes are in some cases 
pale, with the chief part reddish ; in others white, with a central 
black spot, looking, as described by Schmidberger, like a black pupil. 
The antennae were yellowish, dark towards the extremity, which was 
furnished with two seta?, or small bristles ; wings yellowish ; legs 
pale, tarsi pale brownish, or tips of joints and tip of tibia dark. 
By September 1 1 the changes of colour, which accompany 
pairing, and which, in the case of this insect, render it sometimes 
hardly recognisable, were noticeable. Some of the specimens were 
variously patched above with red, some red from head to tail. 
The Psylla does mischief (especially in its earliest stage, when 
it is still wingless) by drawing away the juices with its sucker 
from the buds, or flower buds, or their stalks. It lays its eggs in

autumn near the ends of the shoots, and the little chermes hatch out 
in the spring, much at the same time as the other young orchard 
pests make their appearance. Where these are attended to, the 
apple chermes will need no special applications. They will be in- 
cluded in the same methods of treatment as aphides. 
Hessian fly has, as usual, been of much interest to the general 
public ; but so far as I can judge from the agricultural observations 
and estimates which have been sent me, and taking these in connec- 
tion with the records of the rive years of its total known presence 
in this country, there does not appear to me to be any reason to 
look on this infestation as being of as injurious a nature in this in- 
sular climate as several of our other corn stem pests ; that is, so long 
as the common-sense precautions regularly advised, and based on 
customary methods of agricultural practice, are carried out. 
Presence of Hessian fly attack has been reported to me from 
various localities, mainly in the counties of Hants, Herts, Beds, 
Northampton, Lincoln, Gloucester, Hereford, and Cheshire, and
