144 IMPORTANT NEW WORKS ON ENTOMOLOGY. 
only 294; in other words 155 species, or about one-third of the 
whole, have disappeared. Perhaps we may be permitted 
to doubt whether still further investigation may not lead to 
the re-admission of some of the species rejected by Mr. 
Dawson; at any rate it will be interesting, and possibly 
useful, to collect such gleanings of information about any 
of them as may tend, however slightly, to bring the question 
of their authenticity to a final issue. The pervading spirit 
of Mr. Dawson’s Monograph is that of determined compres¬ 
sion. Thoroughly dissatisfied with the received arrange¬ 
ment, and continually complaining of the confusion into 
which it has been thrown, the author has set himself in 
good earnest to simplify as much as possible; he has applied J 
himself to his task with most laudable patience and assiduity, 
and has evidently turned to good account the great advan- , 
tages of which he was possessed. In conclusion, we will 
only express our opinion that Mr. Dawson has produced a 
very original and useful Monograph, and we hope that 
many other Entomologists may be incited to follow his 
example.”— Natural History Review . 
“ A work that bears internal evidence of invincible assi¬ 
duity and a profound knowledge of the subject. This 
volume is less remarkable for the amount of new matter < 
it contains than for the mass of old and worthless matter 
which it sweeps away. Nothing was ever more extraordi¬ 
nary than the wholesale destruction of names which Mr. 
Dawson has achieved. Those entomologists who had re¬ 
served long gaps in their cabinets, under the fond idea that 
these were to be eventually filled, now find that half the 
names for which this extensive accommodation was prepared 
actually signify nothing, while a large portion of the remain¬ 
ing moiety is comprised of names erroneously applied. . * 
I think that every British Coleopterist is bound to possess 
himself of this valuable volume.”— Address of the President 
of the Entomological Society of London , January , 1855.
