APPENDIX V. 



ARANEIDAE OF THE CLARK EXPEDITION TO NORTHERN CHINA — 

 BY H. R. HOGG, M.A., F.Z.S. 



■yi-IE small collection of spiders herein described were taken during the 



R. S. Clark expedition to Northern China, in the autumn of 1908 and 

 early part of igog, by Captain H. E. M. Douglas, V.C., D.S.O., R.A.M.C. 



The districts from which they came were Yiin-t'ing Shan, in the Chiao- 

 ch'eng Shan, a mountainous forest-country ninety miles west from T'ai-yiian 

 Fu, Shansi, and Yii-lin Fu, in North Shensi, a dry sandy area on the borders 

 of the Ordos desert. 



Owing probably to the time of year, the specimens taken cannot be 

 supposed to represent the Arachnid fauna of the district, an outlying part of 

 what is known as the Indo Malay. A large proportion of the number have 

 not reached the adult stage. 



They comprise eight species of four families, and two of the latter, 

 Argiopidae and Drassidae, are represented by a single specimen only of the 

 genera Araneus, Clerck, and Drassodes, Westring. 



There are three specimens of Thomisidae of the genus Diaea, Thorell, the 

 remainder being all Lycosidae of the genera Lycosa, Latreille, Pardosa, 

 C. Koch, and Evippa, Simon. 



Evippa is a small genus whose members are recorded from the deserts of 

 N. Africa, Palestine, and China; but the distribution of the others are 

 world-wide. 



The Drassodes appears to agree closely with D. lapsus, described by 

 Rev. O. P. Cambridge, from Yarkand,* and the Diaea is perhaps D. subdola 

 Cambr., but none of the others seem to have been previously noted from 

 India, China, Burma, or the neighbourhood. The known species of Araneus 

 and the Lycosidae are so Tiumerous, and many so widely spread, that they 

 may have been recorded from even so far as Japan on the one side, or Western 

 Europe on the other. As I cannot trace them I have taken them to be new 

 species.
