Department of Entomology. 



I, Arrangements and Conservation. 



Exhibition Series. — The revision of the series of economic 

 specimens exhibited in the North Hall has been continued and an 

 exhibit dealing with lac and wax has been added. Owing to the 

 evaporation o£ the spirit, several of the jars containing preparations 

 in spirit have had to be refilled, and where necessary re-sealed ; 52 

 jars in the economic series and 22 in the Insect gallery have thus 

 been dealt with. 



Study Series. — The Department is, as in former years, greatly 

 indebted for the assistance of voluntary workers in the identification 

 of species and in the arrangement of certain parts of the collections. 

 Daring the course of the year the members of the stafE absent on 

 War Service returned to duty at varying intervals and the 

 arrangement and incorporation of specimens in the sections for 

 which they are severally responsible much more nearly approach 

 pre-war conditions. 



In the Coleoptera the expansion and re-arrangement of the 

 C'arabidae have been continued, Mr. H. E. Andrewes having, as on 

 many former occasions, rendered valuable help in the determination 

 and description of new species of Oriental genera. The greater 

 part of the Central American (Godman-Salvin) Collection has been 

 incorporated. The large collection of Hawaiian Ptinidse formed 

 and named by Dr. Perkins has been incorporated. The re-arrange- 

 ment of the Endomychidae has been completed and many new genera 

 and species described. Many species of Melolonthidse, including 

 various important pests of crops have been worked out and described. 

 The Brenthidse of Madagascar have been sent for determination to 

 M. Pouillaude. The re-arrangement of the Phytophaga has been 

 continued, the Cryptocephalinse having been completed, and the 

 Halticinge begun, all types of ih^ latter having been incorporated. 

 Mr. Gr. E. Bryant has again generously placed his services at 

 the disposal of the Department for this purpose. The family 

 Pythidse has been revised and new genera and species described, 

 and revisions of various genera, including Cestrinus, Cissites, 

 Pala'stra, &c., have been prepared. The extensive collection of 

 Heteromera made and presented by Mr. G. E. Bryant has been 

 determined and in great part incorporated, as has a part of the 

 Nevinson Collection and numerous smaller collections from various 

 regions, particularly from M. Vi talis de Salvaza from Indo-China, 

 and from Prof. C. F. Baker, from the Philippine Islands. Mr. 

 G. C. Champion has continued work on the Malacodermata, and 

 re-arranged and incorporated material in those groups which he has 

 studied. 



In the Lepidoptera Rhopalocera the re-arrangement of the 

 Hesperidse has been continued and all accessions, especially the
