By R. Newstead, A.L.S., &c. 
The following Epor of 24 genera and 45 species 
represents about one half of all the species which have been 
found within the British Isles, and far surpasses any other record 
for an equal area. 
Of the 45 recorded eund 11 may be considered gu) peek 
and the remaining found under glass, are exotics, and 
been introduced on im ported plants. Of the latter, 14 have ot 
been found elsewhere in the British Isles ; and deri nia kewensis, 
Newst., a Ripersia filicicola, Newst., have not, so far as is at 
present known, been met with in any other r part of "s world. 
It is importan nt to note that four of the introduced species, 
parisitic fungi, and in the three latter by careful attention and the 
application of insecticides. On the other hand several destructive 
species are apparently on the increase and difficult to check by 
means of insecticides or by ordinary fumigation methods. 
The work of collecting v coccids has been carried on chiefly 
by Mr. Nicholson, F.L.S., who has discovered several interesting

several collections of the Coccide. The results of their researches 
will be found in the volumes of the Entomologist's Monthly 
Magazine. Mr. J. W. Douglas has also dealt with several important 
Species in the same publication.
