the collection of slides has been considerably augmented. Good 

 progress has been made in remounting and transferring the 

 British series of Tineina to other cabinets. 



In the DIPTERA the Tsetse-flies (Genus Glossina) have 

 been worked out afresh and redescribed (with the addition of 

 matter relating to Bionomics, Distribution, etc.), and the results 

 of the revision have been published by the Museum as "A 

 Handbook of the Tsetse-Flies {Genus Glossina)" ; the Glossina 

 material in the . Museum Collection has been rearranged in 

 accordance therewith. 



The family Nemestrinidse has been rearranged, and all 

 material belonging thereto, returned by Herr B. Lichtwardfe 

 after determination by him, has been reincorporated. 



The sub-family Cerioidin8e(fam. Syrphidse) has been worked 

 out and rearranged, and the rearrangement of the sub-family 

 Anthracinse (fam. Bombyliidse) has been commenced. 



New genera and species of Tabanidse and HippoboscidsQ 

 recently received from various parts of Tropical Africa and 

 from Madagascar have been described. 



The family Culicidge has been rearranged, and the whole 

 collection of microscope-slides illustrating their structure has 

 been arranged. A large collection of Indian Anopheles has. 

 been mounted and incorporated, and a number of collections- 

 of African Culicidse and other Blood-sucking flies have been 

 worked out and incorporated. 



The collections of British Syrphidae, Platypezidaj, Pipun- 

 culidee, and Conopidtie have been expanded, and part of the 

 collection of British Simulium has been sent to Mr. P. H. 

 Grimshaw for redetermination. 



A large number of inquiries from various parts of the world 

 concerning Diptera of economic or medical importance have 

 been dealt with. 



Entomological Research Committee. 



As one of the results of the work carried on by the 

 Entomological Research Committee of the Colonial Oflice, more 

 than 30,000 specimens, many representing species of consider- 

 able economic importance, have been added to the Insect 

 collections of the Museum during the year. The importance 

 of the work, and the benefits accruing from it to the Museum,, 

 make it a matter of regret that more adequate accommodation 

 could not be provided for the Scientific Secretary of the 

 Committee and his Assistants than the two rooms allotted to 

 their use in ]910. The congested state of the Insect Room, and 

 the consequent want of available space, made this impossible, 

 but the members of the Stafl" have continued as heretofore to 

 give all the assistance they could to the Secretary ; and most 

 of the setting and labelling of specimens has been done by the 

 preparators employed by the Museum.
