The species is com- 
mon everywhere in the northern 
middle parts of Europe. 
I compared the types of A. Fitch 
(Ps. salicis), of Walsh (Ps. geologus), 
Riley; they are identical. 
Walsh’s specimens are badly gummed 
and of 
on paper; probably the difference in the 
shape of the pterostigma is the conse- 
quence, as the two sides of the wings 
are very loosely connected in the psocina, 
and therefore the venation easily al- 
tered by pasting the wings on paper. 
One of Walsh’s types has the pterostig- 
ma triangular, and rounded posteriorly 
as described by him, the other type has 
the pterostigma identical with C. pedicu- 
I have observed variation of the 
veins in other specimens, but till now no 
variation of the pterostigma. The speci- 
mens from A. Fitch, Riley, and Walsh, 
and from Berlin Falls. are the smallest, 
larius. 
those in the houses in Cambridge and 
from Cuba have just the average size of
