Berlese gives a sketch (91) of the comparative physiology of meta¬ 
morphosis in several orders. 
Pergande’s account (1012) of the cycles of generations of two migratory 
species of Aphidce is very interesting and important. 
Forel (474) continues his critical account of recent publications on 
Insect psychology. 
Silvestri’s papers (1288, 1289) contain some brief but highly interesting 
jiarticulars as to the relations of termitophilous Insects with their hosts. 
Kieffer has completed his important memoir (728) on the biologv of 
Cecidomyiidce , and has also given us a synopsis of the galls of Europe 
(729) arranged according to plants. Dahl’s study (315) of the ethology of 
ants in the Bismarck Archipelago well repays perusal; Ferton (454) 
gives us a series of observations on the instinct and habits of Aculeate 
Hymenoptera , and Adele Fielde an interesting sketch of the life of 
Stenamma (456, 457) in a captive nest. 
Wheeler’s series of papers on the natural history of ants is sure to 
receive attention. Babb (53) has shewn that previous writers have been 
in error as to the stridulation of Passalidce. 
Staudinger & Rebel’s long expected catalogue (1325) of palyearctic 
Lepidoptera has been thankfully received. British entomologists have 
had a welcome volume from the Ray Society (962) in Mr Newstead’s 
Coccidce. Yerrall’s volume (1413) commences the work on British Diptera 
that has for so long been a desideratum. Kraepelin’s list of Insects 
introduced at Hamburg (786) amounting to nearly 300 species is of 
considerable importance. Hutton has completed his enumeration (661) 
of the New Zealand Diptera , but it is certain that only a fragment of this 
division of the New Zealand fauna is at present known. Handlirsch & 
Bischof have discussed the modes in vogue of dealing with local faunas 
(114, 635). Froggatt (505) gives some notes as to the rapid destruction of 
the Australian Fauna. The series of papers on Galapagos Insects of the 
Hopkins Stanford expedition has brought to light sufficient novelties to 
make it clear that a thorough exploration of these islands should be 
undertaken as soon as possible [see Banks (61), Currie (310, 311), Coquil- 
lett (290), Heidemann (608), McNeill (901)]. 
Dr Thebault (1356) assures us that the larvae of Piophila casei can 
traverse the human alimentary canal and give rise to very serious 
symptoms without being themselves killed. 
Townsend has called attention to a remarkable case of resemblance 
between an associated Dipteron and fossorial Hymenopteron (1375). 
Scudder (1254) gives us an important paper on fossil Coleoptera. 
Maeterlinck’s work (870) on the Instinct of bees is really philo¬ 
sophical, well written and interesting, and includes a few original observa¬ 
tions. It is probably the only entomological book that has ever sold an 
edition of 10,000 copies in a few weeks. It has been translated into 
English, Sutro (1344). 
As popular works we may mention Howard’s two books (646, 647), 
Connold’s galls (289), and the translation of Fabre (426). 
Through the kindness of Dr Frederico Philippi I am able to include 
this year several papers on Chilian Insects that I have tried in vain to 
procure previously. 
The work called “Butterflies in amber” by Francis Wyman has not 
been overlooked but is omitted because the only entomological matter in 
it, is the verse that serves as motto, 
“’Tis visible in all the Poet sings 
What of the beautiful his soul hath won : 
As butterflies show on their tinted wings 
The colours of the flowers they feed upon.”
