volumes : Merriam (940). Hutton's list of the fauna of New Zealand is 
a work for which we owe our thanks to the author and his collaborators 
(726) : the Insects occupy about 150 pp. James & Liston Anopheles of 
India is remarkable for the figures of mosquitoes it contains (760). The 
third part of E. E. Green's beautiful work on the Coccidce of Ceylon (620) 
is devoted entirely to the genus Lecanium. The fourth volume of Gangl- 
bauer's valuable work on European Coleoptera includes a statement of 
his views as to the classification of this Order (580). 
Br^ithes (181) records some valuable experiments as to the habits of 
Aculeate Hymenoptera ; they tend to support Eabre's views as to the 
skill displayed in stinging the prey. Adlerz has given a short account 
of the habits of Methoca ichneumonoides, which appear to be of the most 
extraordinary and unexpected nature (16). 
The fact that has given rise to much surprise of the use of larvae by 
ants for the formation of their nests has now been confirmed by its dis- 
covery on the other side of the world, the Messrs Goldi having observed 
that Camponotus senex constructs its nests in this fashion in S. America : 
FoREL (532). The information given by Jacobson & Wassiljew (741) 
adds to our knowledge of the habits of Termitidce, the founding of a nest 
of Hodotermes having been witnessed and described by Jacobson. Miss 
FiELDE & Miss Parker have given an account (508) of a series of 
instructive experiments as to the sense of hearing in ants. Perhaps the 
most interesting of Miss Fielde's papers on ants is that on their power of 
recognition (506). Mr Dwight Pierce has an interesting ethological 
article on hypermetamorphic beetles and their hosts, with special reference 
to the very curious Myiodites (1086). Schwarz (1260) tells us of a grass 
that catches insects in great quantities in Cuba. M. Perraud (1031, 1032) 
as the result of experiments is able to state the conditions that should be 
realised to attract Lepidoptera to light. 
Packard (1006), whose decease will be generally regretted, gives an 
account of the origin of pattern from the Lamarckian stand-point, and 
accompanies it with a very sensible criticism of the fashionable theories of 
mimicry. Kusnezov has published an article (849) calling attention to 
the undeveloped state of the study of the markings of Lepidopterous 
larvae. Entz has a long discussion on mimicry, but unfortunately, as it is 
in Hungarian few of us can profit by it (466). Piepers, who discusses the 
" tails " of Lepidopterous wings, apparently considers them as relicts from 
wings of larger size. 
In the economic department Prof. J. B. Smith's work (1315) on mosquito 
control is the most important production. Dy^ gives (444) a short and 
easily intelligible acount of the relations of Cidicidce and their disease- 
dealing parasites. 
Those who are interested in the — perhaps too extensive — chamber of 
horrors of entomology must not miss the New Congo floor maggot, 
Button, Todd & Christy (418). 
The Polymorphism of ants is discussed by Forel (525) & Emery (452) ; 
the former of whom expresses a little doubt as to its causation. Kellogg 
& Bell contribute a study of variation in 24 species of various Orders, 
and a discussion of general conclusions (783). 
The naming of varieties is at present carried to a great extent, and we 
have not space to record them all, but we endeavour to point out all that 
appear to be of real importance. It may perhaps not be superfluous to 
add that the study of variation is by no means dependent for advancement 
on the naming of varieties.
