occur). The headings just enumerated are those under which Lachneis 
lanestris 18 described. In addition to most of these there are other 
headings in the Psychids—Case, Puparium, Dehiscence of Pupa, &t. 
There are also full details of the ‘superfamilies, families, subfamilies, 
tribes and genera under which the species have been described. 
The feature of this volume will be considered, undoubtedly, the 
very full and complete monograph of the Psychides. This exceedingly 
interesting group has been hitherto practically unknown to British 
lepidopterists, and such authors as have dealt with it have largely 
copied their descriptions and notes from the continental authorities, 
with the result that a very large proportion of the little that has been 
published about them in Britain is erroneous. In this work almo+t 
every British species of the Micro-Psychina, as well as the Macro- 
Psychina, has been worked out in detail and there is no doubt that 
British lepidopterists will now be far ahead of their continental 
brethren in their knowledge of this group, especially as in the Micro- 
Psychina the author has given a summary of the whole of the known 
Palearctic species. A full consideration of their position with reeard 
to other superfamilies and inter se has been given, and the whole group 
has been so thoroughly overhauled that the work will be invaluable to 
continental as well as British lepidopterists. 
The superfamily Lastocampides or Lachneides has been similarly 
treated. The whole of the family has been considered historically 
and the positions of the various authorities discussed. With the 
exception of a few instances, the author finds himself in agreement 
with Aurivillius as to the names to be used, but the life-histories have 
had to be worked out de novo, on modern lines, to determine the 
characters on which the classification of the group should be based. 
The work has been so arranged as to make the facts of the greatest 
possible use to the synonymist, the systematist, the biologist, phenolo- 
gist, and the students of variation and distribution. At the same 
time the collector has unequalled lists of food-plants, dates of 
appearance, full county lists, full account of the habits (larval and 
imaginal) and habitats, mode of pupation, &¢., in such detail as has 
never been offered before. 
Help has been obtained from a very large number of our best 
lepidopterists at home and abroad. Lord Walsingham, Messrs. 
Durrant, Kirby, and Prout are almost entirely responsible for the 
synonymy, Dr. T. A. Chapman and Mr. Bacot for the life-histories, 
descriptions of larvae, pup, &c. Some 250 local and county lists 
have been overhauled and put together for the localities, which form a 
really good series of county lists. Special help has been obtained 
from those who know any species particularly well, whilst considerable 
help has also to be acknowledged from Messieurs Oberthtr, Dupont, 
and Dr. F. J. M. Heylaerts, of Breda. 
As the work can only be continued by the goodwill of subscribers, 
it is hoped that every entomologist who is anxious that we should 
have a series of books on British lepidoptera, that shall be far in 
advance of anything before offered to the entomological public, and 
form a real work of reference, based on the lines of modern science, 
will support this undertaking, not only by becoming a subscriber 
but also by inducing his friends to do so.—H. E. P.
