pair. Conspicuous thick but short Mack liairs on hind femora, 

 longest on under side, and on front and hind sides of hind tibia?.

The above redescription is from three perfect d 6 in the Indian 

 Museum from Tolpaiii, Garhwal District, W. ]Iimalayas, 9500 ft., 

 23. iv.-13.v. 1914; Simla, x. 1911 [Uoiulett). The type c? in the 

 British Museum agrees perfectly. 



This is the most striking of tlie Oriental species known to me, 

 the very conspicuous, dense black hair on the hind femora and 

 tibijB being quite unknown in any other. The pinkish and 

 grey bands of the abdomen are also very characteristic. The 

 species beafs a close general resemblance to S. ;/riseocinctus, but 

 this latter is immediately recognised by the pubescent eyes and 

 by tlie absence of the black hair on the hind legs.
