purposes, and tlie years 1907 to 1916 nearly completed, Mr. 

 H. T. G. Watkins has given considerable assistance by voluntarily 

 rearranging the Pierine genera Pieris, Colias, and Gonepterya?, 

 and incorporating all accessions at the same time. 



In the Heterocera the classification and rearrangement of the 

 Anerastiinse have been continued, the Dioptidse rearranged, and 

 the collection of the Lasiocanipidae expanded. A large collection 

 of moths made by Mr. E. J. Godfrey in Siam has been worked 

 out. 



In the Tineina and Pterophorina much unarranged material 

 has been catalogued, determined and incorporated, and types 

 and typical material have been identified and labelled. The 

 large collection of separata presented to the Walsingham Library 

 by Sir George F. Hampson has been catalogued and the exact 

 references indicated (over 4,000). 



In the Diptera the African Tipulidae, determined by Dr. C. P. 

 Alexander, and the exotic Psychodidse, determined by M. A. 

 Tonnoir, have been received back and reincorporated ; the large 

 collection of exotic Anthomyiidse has been sent to Mr. J. R. 

 Malloch for determination ; the collection of British RhyphidsB, 

 Psychodidse, Ptychopteridse and Limnobiinse has been ar- 

 ranged ; the spirit collection of Dipterous larvae and adults has 

 been rearranged in filing cabinets. A series of Tabanidse, 

 chiefly from Africa and North Russia, has been worked out, 

 described and incorporated. A series of named Nearctic and 

 Neotropical Muscoidea, received in exchange from the United 

 States National Museum, has been labelled and incorporated, 

 while a small series of economically important Australian Calli- 

 jihorinae and Muscinae has been determined and also incor- 

 porated. A large number of miscellaneous accessions have also 

 been made to the General Collection. The official '* Instructions 

 for Collectors," Nos. 4, 5, 6, and 7, have been revised and 

 edited (for a new edition of " Handbook for Collectors"), while 

 during the year " A Handbook of British Mosquitoes " has been 

 published. 



In the Hymenoptera the parasitic families Chalcididae and 

 Haltichellidae have been arranged, and the Agaonidae and Eury- 

 tomidse partially completed. Work has also been done on 

 isolated genera belonging to various families. In the Ichneu- 

 monoidea the Australian genus Poecilocryptus has been arranged 

 and monographed in conjunction with Mr. R. E. Turner. • The 

 African genus Oneilella has also been arranged. Several col- 

 lections of general Hymenoptera — particularly from Eastern War 

 areas — have been determined. Parasites of the Frit-fly, Wheat 

 Pests, Forest Pests, pests affecting the Cabbage and Turnip, 

 Calli'phora, Musca, and Glossina, have been determined and 

 described. In the Tenthredinidae the Rev. F. D. Morice has 

 completed the rearrangement of the family, and Prof. T. D. A. 

 Cockerell has kindly assisted in incorporating a set of Apidae 

 presented by the United States National Museum.
