REVIEWS. 
The Transactions of the Entomological Society of London, 
for the year 1878. 
JUDGED by quantity or bulk the volume for 1878 must yield 
to its predecessors, as it contains but 335488 pages and six 
plates against 439+93 pages and ten plates in the volume for 
1877, 655+87 and twelve plates for 1876, 342+68 and nine 
plates for 1875, and 548+70 and eleven plates for 1874. 
Judged by the more severe test of quality it can hardly be said 
to equal, certainly not altogether to surpass, any of the last few 
volumes. In the Transactions of a society lke the KEnto- 
mological it 1s quite idle to expect them to maintain a given 
standard of excellence; as here, so in other cases, certain 
important and interesting memoirs come spontaneously and 
nregularly, not in answer to any given call or need. 
There is still much to learn from the volume for 1878, and 
to that we more particularly limit ourselves, the present article 
being intended more as a digest than for a review. ‘Thirty-one 
memoirs, from nineteen contributors, are printed—a larger number 
than has appeared in any volume since the first of the 38rd series 
(1862-4); twenty-one of these relate to descriptions and lists of exotic 
species. Classification is the subject of one; habits and economy, 
five. ‘There is one on structural peculiarities—the hairs of bees 
—-which may be useful in throwing hght both on economy and 
classification; two concerning the colour and forms of larve, 
which come somewhat indirectly within the now wide range of 
Darwinism, and one on practical Entomology. ‘This last is a short 
paper by Miss E. A. Ormerod, on “‘ The Prevention of Insect 
Injury by the use of Phenol Preparations.” A detailed account 
of how the use of the preparation checked an attack from the 
“rust” fly (Psila rose) in the carrot, is given. The two papers 
bearing on the great natural selection theory tend altogether to 
bear out the views of Wallace, Darwin, Weismann, and others, 
viz., that, as a general rule, edible caterpillars are dull or
