6 PREFACE 



valuable series on the Tetriginae (Orthoptera) of the Hope 

 Department, by Dr. J. L. Hancock, the description of a new 

 moth from New Zealand (15) by Mr. E. Meyrick, as well as 

 the late Mr. R. Shelford's papers in this volume and its 

 Appendix, already referred to. Notes on the moths of the 

 1 Dale Collection ' (22) are contributed by Commander J.J. 

 Walker, and on the Orthoptera (23) by Mr. W. J. Lucas. 

 A third supplement to the beetles of the Oxford district 

 (24) has been written by Commander Walker, and notes on 

 the life-histories of two British beetles (25) by Mr. A. H. 

 Hamm, and of another by Mr. Joseph Collins (26). 



It is a pleasure to include for the first time a series of 

 papers (27-33) by Mr. R. S. Bagnall on the difficult groups 

 he has done so much to elucidate — the Thysanoptera 

 (Thrips) and the Myriopoda. 



The progress of the Hope Department in 19 10, 191 1, 

 and 191 2 may be traced in the Annual Reports (37-39). 



All the nine memoirs in the separate Appendix have 

 been mentioned above except (8), a paper on the external 

 structure of the Lepidopterous pupa published by the 

 Professor in 1890. It so happened that the remaining 

 separata were just sufficient to supply the issue, and it was 

 thought that they might be usefully employed in this way. 

 At the same time it may not be out of place to inform 

 readers who are interested that the subject was continued 

 in another paper of which separata are not available. 

 This second paper, containing parts IV-V, was published, 

 like the first, in the Transactions of the Linnean Society. 

 (Vol. V, Pt. 7, 1 891, p. 245.)
