rearranged several families in the British Collection, and in 

 1902-1903 worked out the Tsetse-flies (Glossina), upon which he 

 published a monograph in the latter year. In 1903-190 1 In- 

 rearranged those portions of the general collection comprised in 

 the families Hippoboscidse, Nycteribidde, Streblidse, and Muscidse 

 Calyptratse down to the end of the section Butilia, and in- 

 corporated the extensive series of Central American material 

 belonging to these families contained in the Godman-Salvio 

 collection. The first portion of the Tabanidse (including the 

 Pangoninse and the genus Hsematopota) were rearranged by Bliss 

 Gertrude Kicardo between 1900 and 1904, and between 1898 

 and 1904 the Midaidae, Conopidse, and part of the Bombylidse 

 were similarly dealt with by Lieut .-Colonel J. W. Yerbury. 



Rhyxchota. 



This Order was arranged and partly named up by Mr. Adam 

 White prior to 1850, and the Hemiptera Homoptera were 

 rearranged by Mr. F. Walker and catalogued between 1849 and 

 1852. In 1851-2 Mr. W. S. Dallas prepared a list of these 

 families of the Hemiptera Heteroptera (Pentatomida?, Coreidae 

 and Lygseidae), which he appears to have arranged in 1853 ; the 

 whole Heteroptera were subsequently rearranged and catalogued 

 by Mr. Walker between 186G and 1873. In 1874 Dr. A. G. Butler 

 rearranged a portion of the Homoptera, which then numbered 

 10,161 specimens, referable to 4046 species, and completely revised 

 many of the genera and the whole of the New World Mem- 

 bracidse. In 1895 Mr. W. F. Ivirby rearranged the dcadidse. 

 In 1897 Mr. E. A. Waterhouse commenced a rearrangement of 

 the British Hemiptera, which was completed in 1899 ; and in the 

 latter year Mr. W. L. Distant commenced a complete revision 

 and rearrangement of the general collection of the Order; hr has 

 completed the Heteropterous section and is now at work on the 

 Homoptera. 



Aptera. 



For many years these were crowded together, withoul much 

 pretence at arrangement, in three or four cabinet-drawers, the 

 only exception being that the British Anoplura were placed in 

 the order of the list published by the Trustees in 1852, but 

 without special labels. These were all gone over and arranged 

 by Dr. Butler about 1873, and have not subsequently been 

 rearranged.
