346 MR. R. S. BAGNALL'S REPORT OF 



including Trichopsylla dalei Rothschild, T. vagabundus 

 {insularis Rothschild), Typhlopsylla dasycnemus Rothschild, 

 T. pentacanthus Rothschild, and Ctenopsyllus spectabilis 

 Rothschild ; 4 ticks, including a recently described species, 

 Ixodes caledonicns Nuttall, from the starling ; 5 Hippoboscid 

 flies including Oxypte?~ii?n pallidum Leach, from the swift, 

 observed by Mr. Alaric Richardson • 6 bloodsucking lice 

 (Anoplura) and 84 bird lice (Mallophaga), of which over thirty 

 are for the first time recorded from Great Britain. Two of 

 these are apparently new, one taken by Mr. Charlton on the 

 teal and the other by Mr. Gill from the little auk, whilst others 

 have only recently been described from North America. 

 There remain numerous birds we have not yet had the 

 opportunity of examining. The study, too, has led to 

 interesting data in regard to the ancestry and evolution of the 

 host species. 



In 1907 Prof. Silvestri diagnosed a new order of curious 

 primitive insects, Protura, the Italian species of which have since 

 been monographed by Berlese. I have had the pleasure of 

 discovering, locally, specimens of the three genera falling into 

 the two families of this order, Acerentomidae and Eosentomidse. 

 Some of my species are evidently new. 



As regards the Myriapoda enough has already been said, 

 so that I must now proceed with my report after a few words 

 on my favourite insects, thrips or Thysanoptera. My collecting 

 in this group has been carried out almost entirely at our field 

 meetings. Amblythrips ericce. Bagnall, and Bagnallia agnessce. 

 Bagnall, have been taken in new localities, including numerous 

 examples of the previously unknown male of the latter; Mr. 

 H. S. Wallace discovered a new species at Whitfield, 

 Physothrips latus Bagnall, of which Mr. Hull sent me further 

 examples later; whilst Prof. Karny, of Elbogen in Austria, has 

 shown that the elm-leaf thrips taken by myself in the Derwent 

 Valley and Teesdale differs from the type of Liothrips 

 hradacensis Uzel, to which I referred the species ; the species 

 is now known as Hoodia bagnalli Karny. At the Harbottle
