INVERTEBRATES COLLECTED ON THE EXPEDITION — 

 BY ARTHUR DE C. SOWERBY. 



IN this branch of zoology the work done was not very extensive, though the 

 results have proved to be of some interest. The greater part of the work 

 was carried out by Captain H. E. M. Douglas, V.C, D.S.O., R.A.M.C, who 

 made collections at T'ai-yuan Fu and in the Chiao-ch'eng Shan district in 

 Shansi, and also in northern Shensi. 



The collections contained representatives of nine orders, viz. : — Coleoptera, 

 Hymenoptera, Hemiptera, Mallophaga, Diptera, Siphonaptera, Scorpiones, 

 Aranese, Acari. The Lepidoptera and Neuroptera were collected by Mr. 

 Grant and myself. 



It was unfortunate that the season was so far advanced when the 

 expedition commenced. As a consequence this work suffered considerably. 



The collection was sent first to the Royal Army Medical College, but 

 was subsequently presented to the British Museum (Natural History) in 

 exchange for the identification of the specimens it contained. Many species, 

 represented by single specimens only, have been left undetermined, while the 

 bad condition of some specimens has rendered their identification impossible. 



For the identification of the various species contained in this collection, 

 thanks are due to the following specialists : — 



E. E. Austen (Diptera). 



C. J. Gahan (Coleoptera). 



G. Meade-Waldo (Hymenoptera). 



S. Hirst (Scorpiones and Acari). 



— all of the British Museum. 



The Hon. N. C. Rothschild very kindly undertook the identification of 

 the Siphonaptera, while Mr. H. R. Hogg, has been equally kind in working 

 out the Aranese.* Good results have been obtained in the two last orders, 

 some eight new species having been described. 



Altogether the following new species were contained in the collection. 



In the Acari, two undetermined species belonging to the genera 

 Hsemaphysalis and Leiognathus.
