I have received both the typical and varietal form from Ceylon. 

 According to Capt. Hutton(si?;2"'fO' ^™i^ observations on the insect 

 made at Mnssooree, the white sugary secretion which it produces 

 is only obtainable throughout the dry weather from Januarv to 

 June, as it is washed au ay by the first heavj^ rain that falls upon 

 it. The eggs hatch iu December, and the larvae cluster like sheep 

 upon the food-plant. They feed by sucking the juices of the 

 leaves, and moult several times, gradually increasing in size until 

 the setting-in of the rainy season in June, when winged imagos 

 begin to emerge, Mr, R. II. E. Thompson noticed that in Garhwal 

 the natives eat the sugary secretion and call the insects Dharheri, 

 i. e. " sheep," on a,ccount of their habit of clustering together and 

 jumping away when disturbed. Mr. W, P. Thomas ascertained 

 that the Koorkoos and other ti'ibes in the jS^arsingpur district of 

 the Central Provinces kno\v the insect, but make no use of the 

 sugary secretion, which they say has a narcotic effect when eaten. 

 In this district the insects were found on the green succulent 

 coppice-shoots of Elceodendron rocvhurgliii.

Body ochraceous, abdomen strongly cretaceously tomentose ; 

 legs greenish, the tibiae darker; head with the lateral ridged 

 marg'ins greenish ; pronotum and mesonotum very finely sprinkled 

 with black ; tegmina pale greenish, more or less cretaceously and 

 tomentosely finely maculate, the costal and claval areas palely 

 sanguineous and also cretaceously maculate ; the under surface of 

 the tegmina is more cretaceously tomentose than above ; wino-s 

 pale lacteous much suffused with ci'etaceous ; general structural 

 characters as in P. margiiiella. 



In some specimens the ground-colour of the tegmina is reddish-
