Systoechus socius, Walk. 



Ins. Sauud. Dipt. pt. 3, p. 201, 



Near Theog, 7,000 ft., 14-v-og. This seems a fairly well dis- 

 tributed species extending from the Himalayas to Ceylon ; 

 Kashmir, Kumaon, Dehra Dun, Sikkim, and the Kangra Valley, 

 and several localities in Ceylon.

Common on Sedum rosulatum, the white stone-crop at 

 Simla, 16-V-09, where Dr. Annandale first discovered it. He found 

 it again at Phagu on the same plant, 18 — 21-V-16. The sexes 

 exhibit some difference in the markings of the head and thorax. 



Usia marginata, Brun. 



Rec. I lid. Miis._ III, p. 228. 



A single cf taken by Dr. Annandale at Simla in company with 

 the first series of U. sedophila.
