more slender than the preceding joints, and is rather longer than 

 the fifth and the sixth joints together : the eyes are red, and 

 rather prominent : the tip of the mouth is brown, and reaches 

 the middle hips : the nectaries are very short, and not more than 

 one-twentieth of the length of the body : the legs are rather 

 short ; the tips of the feet are brown. 



1st variety. The feelers are less than half the length of the 

 body. 



The oviparous ivingless female. The body is spindle-shaped, 

 and contains two eggs : the feelers are rather less than half the 

 length of the body : the hind-shanks are not dilated. 



The wingless male. It has a narrower body, and longer and 

 stouter legs than the female : the body is nearly linear, and ob- 

 tuse at the tip : the feelers are much stouter than those of the 

 female ; the fifth joint is shorter than the fourth ; the sixth is 

 much shorter than the fifth.

Sometimes above eight hundred insects of this species feed 

 together under a single leaf of the willow, S. caprea, from the

 the time for the appearance of the male and of the oviparous 

 female.

 entelloid group of monkeys is represented over the low northern half 

 of that island by a peculiar species, of which Dr. R. Templeton (late 

 of Colombo) has favoured me with a living adult male, which I have 

 since figured and described by the name Pr. thersites, Elliot (J. A. 

 S. B. xvi. 1271). I have given coloured figures also of Pr. entellus 

 (verus), Pr. priamus, Pr. hypoleucos, Pr. Johnii, Pr. cephalopterus 

 (three varieties of colour), Pr. pileatus and Pr. Phayrei. There is 

 another large monkey in Ceylon, peculiar to the elevated and colder 

 parts of the island*, which remains to be examined, but would seem 

 to be very probably Pr. Johnii, which is common in the Neilgherries ; 

 and Dr. Templeton assures me of the existence of a small monkey 

 probably undescribed, — all additional to the well-known Pr. cephalo-
