APPENDIX III. 
INVERTEBRATES COLLECTED ON THE EXPEDITION— 
BY ARTHUR DE C. SOWERBY. 
N 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-yiian Fu and in the Chiao-ch’éng Shan district in 
Shansi, and also in northern Shensi. 
The collections contained representatives of nine orders, viz. :—Coleoptera, 
Hymenoptera, Hemiptera, Mallophaga, Diptera, Siphonaptera, Scorpiones, 
Aranez, 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 Aranez.* 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 
Hezmaphysalis and Leiognathus.
