The tarsal digitules are simple hairs, and there is a distinct tooth one- 
third the length from the tip of the claw. The caudal lobes are pro- 
minently produced, and bear the usual setae, which average 210 in 
length, and, in addition, two shorter hairs and three stout spines. The 
setae of the anal ring are about 135 fi long.

37a. PsEUDOCOCCUs stelli var. tylococciformis sp. n. var. n. 
(Plate XVIII., Fig. 21.) 
On the twigs with Ps. stelli were a few specimens identical in appear- 
ance except that the body was beautiful rose-pink in colour instead of 
yellow. The waxy secretion was exactly similar, and when mounted the 
legs, antennae, etc., were also identical, but the lateral spine areas were 
produced on small truncate tubercles (Fig. 21). The insects showing this 
character were on an average slightly smaller than the adults of stelli, but 
the antennae were uniformly 9-segmented.
