196 THE entomologist's record. 



occur). The headings just enumerated are those under which Lachneis 

 lancstria is described. In addition to most of these there are other 

 headings in the Psychids — Case, Puparium, Dehiscence of Pupa, &C. 

 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 almost 

 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 Avhole of the known 

 Palsearctic species. A full consideration of their position with regard 

 to other superfamilies and inter sc 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 LosiocMiipidci; or Lachiieides 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. Sec, 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 larvte, pupte, &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 Oberthiir, 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.
