INTRODUCTION. 
The most remarkable discovery of the year is the unsegmented animal 
considered by Adensamer (7) to be the female imago of a pupiparous 
Dipteron. 
Much greater attention has been given to TermitidfB than was ever the 
case before. Haviland describes (463) a large number of new forms, so 
that his paper with those of Wasmann (1153) and Froggatt (370) just 
about double the number of described forms. The illustrations of Australian 
Termitaria by Saville-Kent (957) are very valuable. 
The eighth Vol. of Dalla Torre’s (229) Catalogue brings this im- 
portant work within measurable distance of completion. This volume is 
entirely devoted to fossorial Hymenoptera and is the most bulky of the 
series. 
Sir George Hampson has continued his remodelling of the taxonomy of 
Pyraloid moths by the treatment of several families (452, 453). 
Faunistic works are as usual both numerous and important. The 
Biologia Centrali- American a (416) has made fair progress. Colonel 
Bingham’s Volume (76) on the Hymenoptera of British India is a valuable 
addition to entomological literature. IIormuzaki’s papor (495) on the 
Lepidoptera of the Bukowina deserves notico ; Kerremans’ memoir (567) 
on the Buprestidce of Brazil contributes no less than 235 new species. 
Mr Meyrick has treated the Australian Elachistidce , recording 254 species, 
nearly all of which are new (747). Lord Walsingham (1139) records 
302 species of Micro-lepidoptera from the West Indies; Cuba has as yet 
produced only 23 species, though it probably shelters several hundred. 
One of the most considerable faunistic works is that of Davis on 
N. American Tryphonince (234). Coquillett (218) on N. American para- 
sitic Diptera is also important; and Casey (162) has added a large number 
of new species of Coleoptera to the N. American fauna. 
In Morphology we may call attention to Genthe’s paper (396) on the 
comparative anatomy of the mouth-parts of Micro-lepidoptera ; to Perez’s 
discovery (824) of a new kind of bee proboscis ; to Bordas’ extensive 
investigations (104-109) on the internal anatomy of Orthoptera\ and to 
Bruel’s (137) anatomy and development of the sexual ducts and annexes in 
Muscidce ; while KlafAlek’s memoir on comparative anatomy of Perlidce 
(593) appears to be of considerable value, and Pratt’s account (881) of 
imaginal discs in Diptera will be found very useful by students of 
metamorphosis. Meinert’s (736) views as to the morphology of mouth- 
parts will require careful consideration. 
Kulagin (642) has made another contribution to the embryology of 
parasitic Hymenoptera, and Dr Heymons has given us an opportune 
sketch (478) of the development of a Thysanuran. 
The most important work on embryology is however the history of the . 
development of a Mason-bee by Carri&re and BUrger (161). The 
work is divided into two parts ; it was commenced by Prof. Carrikre, and 
after his decease prepared for publication by his colleague, who appears 
to be chiefly responsible for tho second part of the work. They confirm 
the view, previously put forward for Orthoptera , that the mesenteron 
is derived either from ectoderm or directly from blastoderm. 
Tho publication of a fifth volume of Fabre’b “Souvenirs” (303) is 
welcome. It gives details of the habits and life-histories previously 
unknown of several common Mediterranean Insects. Unfortunately the 
volume exhibits, in more than one place, an inadequate acquaintance 
with the work of other Naturalists. None the less important and in- 
teresting because of its brevity is Pantel’s sketch (819) of the larval
