INTRODUCTION. 
The amount of entomological work we record this year surpasses the 
previous maximum: the titles being 1251 in number, against 1173 last year. 
We find in this year’s list several works of a more comprehensive nature 
than usual. Comstock (245) discusses all the orders of Insects, limiting 
himself only by the extent of the North American fauna. The 
Recorder (1055) has published the first part of a work on the Natural 
History of the Insects of the whole world ; and Mi all has given us a 
very interesting volume (767) on the Natural History of Aquatic Insects 
of our own country. 
We are indebted for a monograph of the Pseudophyllides to Hofratii 
Brunner von Wattenwyl ; to Brauer & Bergenstamm (139) for 
the concluding part of their attempt to reorganise the system of 
one of the most complex divisions of Diptera. It will be generally 
regretted that the decease of Herr von Bergenstamm should have fol- 
lowed so closely on the completion of this work. R^GIM bart’s revision 
of the Dytiscidce of Africa and Madagascar is remarkable from the great 
proportion of new forms it describes of a family that has been previously 
not altogether a neglected one. The monograph of Pepsis , by Lucas 
(705), and the completion of Handlirsch’s series of papers (486) on the 
Bombecini deserve recognition; while Hampson’s (482) revision of the 
Crambinm will no doubt prove very useful. 
The valuable list by Champion (197) of Tenebrionidie described in the 
last twenty-five years, shows that the number of known genera and 
species has been just about doubled in that period, more spocios having 
been described in the last twenty-five years than in the previous 
century. 
Dyar has published several important studies on the classification of 
Lepidopterous larvae, which are perhaps more interesting to the phylo- 
genist than to the systematic worker or naturalist. Uzel’s work on 
Thymnnptera will be welcomed, as it deals with the most neglected of 
the orders of Insects ; it is chiefly devoted to the Thysanoptera of 
Bohemia, but little material from other parts of the world haviug been 
at the author’s disposal. After an interval of many years, the student of 
British Lepidoptera has another handbook for the determination of his 
species (764). Meyrick’s system is based almost exclusively on wing- 
neuration, and therefore differs totally from that of Stainton ; time 
only can show whether Scudder is right in believing that the system of 
thirty years hence will bo as different from Meyrick's as this is from 
Stainton’s. Ganglbauer’s second volume on the Coleoptera of Central 
Europe (416) is a valuable addition to the series of existing works on 
this part of the world’s fauna. 
In anatomy we find a series of papers on Hymenoptera by Bordas ; 
his account of the Malpighian tubes is comprehensive and succinct. 
Dr. Meijere’s (754) illustrations of the compound stigmata of certain
