130 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



In the Rhynchota tlie incorporation of tlie Distant Collection 

 lias been continued and completed, and named collections of 

 American Tingid83 and Aradidse have been incorporated. Many 

 minor collections from various localities have beeif similarly dealt 

 with. In the Coccidse, collections from various parts of the 

 world have been worked out, and good progress has been made 

 w^th the rearrangement of the family. In the Aphidse and 

 Aleurodidce, many small collections have been determined and 

 incorporated. 



In the Orthoptera valuable help in the arrangement and 

 identification of species and genera was received during the second 

 half of the year trom Mr. B. Ilvaroff, Assistant in the Imperial 

 Bureau of Entomology. 



Mr. Heibert Campion, also of the Imperial Bureau, has 

 voluntarily rendered considerable seivice from time to time by 

 the determination and description of Odonata. 



In the Thysanoptera most of the unmounted material of the 

 unnamed microscopic species has been transferred to slides, ready 

 for determination. 



In the Mallophaga and Anoplura the Denny and General 



Collections have been mounted on slides for study purposes, and 

 are now being revised and catalogued. Several odd collections 

 have also been worked out. 



Imperial Bureau of Entomology. 



The Collections of the Entomological Department continue 

 to benefit by the work done by the Imperial Bureau of Entomo- 

 logy. During the year this organisation presented some 8,000 

 specimens, mostly named, and including the typesi of 71 new 

 species. The assistance given by members of the staff of the 

 Bureau in naming and arranging parts of the Museum collection 

 has been referred to above. As a considerable part of the work 

 of the Bureau is carried on, and needs to be carried on, within 

 the Museum, it is much to be regretted that it has not yet been 

 found possible to increase the accommodation jjrovided for the 

 work of its staff in the Museum. The Entomological Deparf- 

 ment itself suffers equally through want of the necessary space.
