The collection of Dermaptera brought back by Mr. Stanle^^ 

 Kemp from the Abor Expedition contains, as was to be expected, 

 matter of considerable interest. It consists of thirty-one recog- 

 nizable species, of which five are new to science; one is the third 

 known specimen, and first known female, of a species alread^^ 

 recorded from Burma and Assam ; another species is added to the 

 Indian list, being hitherto known only from a pair from Tonkin. 

 The remaining species are well-known Himalayan, Burmese and 

 generally Oriental forms. 



Superfamily PROTODERMAPTERA. 



Family PYGIDICRANIDAE. 



Subfamily DIPLATYINAE. 



Genus Diplatys, Serv. 



The collection contains seven specimens, all, unfortunately, 

 immature, and not therefore specifically determinable. They all 

 present the long segmented caudal setae characteristic of the 

 larvae and nymphs of this genus. The specimens were all taken 

 between December 24th, 1911, and February 9th, 1912, under 

 stones, on the banks of small streams. The exact localities are 

 as follows : — 



Dibrugarh, 17 — i9-xi-i9ri. No. ^^. 



Rotung, 1400 ft., 24-xii-ii, under stones on bank of small
