In the Araneae, five species — 



1. Lycosa clarki. 



2. Lycosa ordosa. 



3. Evippa douglasi. 



4. Pardosa shansia. 



5. Pardosa sowerbyi. 



In the Siphonaptera, three species — 



1. Ceratophyllus subcsecatus. 



2. Neopsylla anoma. 



3. Vermipsylla dorcadia. 



In the case of the two new species of Acari, Mr. Hirst has been unable to 

 publish descriptions, but he hopes to do so later. 



The chief interest attached to the collection is the locality in which it 

 was made. No previous collections have been made in the same district. 



Most of the species are representative of very widely distributed genera. 



On the return journey from Lan-chou Fu to T'ai-yiian Fu, Mr. Grant 

 and I made a collection of butterflies and dragonflies. This was forwarded, 

 with the mammals, to the Smithsonian Institution. A description of this 

 journey and the country where these insects were most prevalent appears in 

 another chapter so it need take up no space here. At the end of the present 

 chapter appears a list of the butterflies. I received no report on the collection 

 from the Smithsonian Institution, and have been forced to make up the list 

 myself, trusting largely to memory, and to the coloured plates and descriptions 

 in Leech's " Butterflies of China." 



In northern Shensi where the climate is dry and vegetation scarce, 

 butterflies and dragonflies are comparatively rare, while scarcely any were 

 seen west of Ching-ning Chou in Kansu. In the mountains of Shansi 

 butterflies are plentiful and the marshes and rivers of the plains in the same 

 province support many species of dragonflies. Nowhere however, on the line 

 of march, were either of these orders seen in such quantities as in the loess 

 valleys of eastern Kansu and central Shensi. 



Whether any of the species collected in these localities are new I cannot 

 say. 



Specimens of a fresh water crab were obtained by me in the mountain 

 streams south of Hsi-an Fu in Shensi and also near T'ai-pei-ch'6ng in eastern 

 Kansu. They belong to the genus Poiamon.
