MonocRAPHI£ DER FAMILIEN DER PFLANZENLAUSE (PHYTOPHTHIRES). Von J. 
H. KatrenspacuH. Aachen, 1843. 8vo. 222 pp., and one plate. 
It is rather remarkable that, whilst the extraordinary physio- 
logical peculiarities exhibited by the Aphides, in respect to their 
modes of reproduction, have attracted the notice of every Natur- 
alist, so few attempts have been made to describe the very 
numerous species of which the family consists. It is true, nume- 
rous species are indicated by Linnzeus, Fabricius, and others, but, 
with scarcely any other description than that of the name of the 
plant on which they are found. In our own country, many species 
were well figured by Harris, long ago, in his ‘‘ Exposition of 
English Insects,” and a most extensive series of species, together 
with the plants which they attack, was formed by Mr. Haworth, 
who was induced to place them in Mr. Donovan’s hands, with the 
view to their publication with figures; the latter author giving up 
to Mr. Haworth, in return, a unique specimen of the splendid 
Indian grasshopper, since published by Donovan, under the name 
of Gryllus Donovani, in the Naturalist’s Repository. Unfortu- 
nately, the latter never proceeded with the contemplated work : 
the collection, formed with so much care, was returned, half-eaten 
by mites, to Mr. Haworth, and at the sale of his collection, it 
fetched the price of one shilling !
