considerable part of his time to naming and arranging the 

 Scolytida3. 



In the Hymenoptera, the re-arrangement of the Apidse has 

 been continued, the sub- family NomadinsD being completed and 

 considerable progress made with the sub-family Anthophorinse. 

 A number of accessions has also been incorporated in other 

 families, and in the Vespidae a partial re-arrangement has been 

 effected. The collection has continued to benefit very much by 

 the help of specialists, loans of specimens having been sent to 

 Dr. A. Mocsary (Chrysididie), and Prof. T. D. A. Cockerell 

 (Apidse), who have returned them, to Dr. Franklin (Apidaj), 

 and Herr Bischoff' (Mutillidae), who are still engaged on their 

 respective consignments. Mr. Claude Morley has continued the 

 work of determining, re-arranging and incorporating the 

 Parasitic Hymenoptera (Ichneumonidse), special attention 

 having been given to various tribes in the sub-families 

 Pimplinae, Tryphonime, and Cryptin^ie. Part II. of tho 

 " Hevision of the Ichneumonidse '" was published during the 

 year. 



In the Neuroptera, a considerable amount of material of 

 the sub-family Calopteryginse (Odonata) has been studied by 

 Dr. Ris. of Rheinau, Switzerland. SenorR. P. Longinos Navas, 

 S.J., of Saragossa, has continued to woi'k out the Chrysopidte 

 and Mantispidae of the Neuroptera Planipennia, and has 

 described a great number of new genera and species from the 

 Museum collection. Among the accessions, a considerable 

 number of valuable British Phryganeidse, Ephemeridae, and 

 Sialidse have been presented by Mr. Martin E. Moseley and the 

 specimens prepared for exhibition. A stud}^ of various diag- 

 nostic characters used in the classification of the Phryganeidae 

 has been made. 



The collection of the Anoplura and Mallophaga continues 

 to grow, large numbers of specimens having been presented by 

 the Hon. N. C. Rothschild. The whole of the types have been 

 transferred from cards to slides and mounted in Canada balsam. 

 Several new species have been described, the specimens in the 

 slide cabinet re-arranged and an index commenced. Some time 

 has also been devoted to the study of Denny's types. 



The large collection of Rhynchota made in the Seychelle 

 Islands by the Percy Sladen Trust Expedition has been partly 

 worked out, the whole of the Heteroptera having been incor- 

 porated. A considerable number of new species and genera 

 of Cicadidse from Indo-China, New Caledonia, British India, 

 Australia, and Tropical Africa has been received. Another 

 instalment of the Distant collection has been purchased. A 

 large number of Coccidse on slides, determined by Prof. Robt. 

 Newstead, F.R.S., and presented by the Imperial Bureau of 

 Entomology, are being arranged in the further cabinet accom- 

 modation provided. 



In the Thysanoptera, many valuable and important new 

 species and genera have been described by Mr. R. S. Bagnall 

 and incorporated on their return.
