I have recently, through the kindness of Sq./Ldr. G. R. Radford, had the pri- 
vilege of studying two specimens of what must be referred to this species or to a 
variation of it, from Colombo, Ceylon. The specimens were collected by Sq./Ldr. 
Radford on 30th Aug., 1944. 
The two specimens are both somewhat smaller than the dimensions given by 
Canestrini and Berlese, namely, 975p long by 675y, as compared with 1800p and 
1250u respectively. The front tarsus is 210» long by 110, high, giving a ratio of 
1:0:1-91, whereas Berlese’s figures give a ratio of 1-0: 2-0, the metatarsus, 146. 
long, is rather shorter in proportion to the tarsal length, giving 1-0:1-17. The 
dorsal setae are of the two forms as figured by Berlese, although the large decum- 
bent seale-like ciliated setae measure only ca. 354, as compared with 60p given by 
Berlese. Strictly these setae are not scale-like, but have the lateral margins in-
