400 Mr. Forsayeth on the life-history of 



Cocoon of silk, attached by greater length to stem of 

 grass. An opening defended by hairs exists at inferior 

 extremity for egress of imago. Head of pupa towards 

 this aperture. 



From a cocoon spun on Sept. 1st an imago came out 

 on night of Sept. 11th. It occupied, when at rest, the 

 position shown in the sketch, the front legs stretched 

 out in advance of the head, and was sluggish and not 

 easily excited to move during the day. 



Parasitic on this larva is a large yellow-bodied insect 

 like a sawfly, with long antennae, which are perpetually 

 in a state of tremulous motion. A single parasite 

 occupies a whole pupa. 



Euproctis lunata, Walk. (PL XIV., figs. 5 — 5 c). 

 Mhow, September 23rd, 1879. 



The eggs, covered with down from the abdomen of the 

 female, are deposited in oblong masses on the twigs of 

 Acacia Gummi-arahicce and allied species (PI. XIV., 

 fig. 5 a). The larvae feed on leaves of above tree, also 

 on Zizijphus jujuha and garden rose. 



The larvEe hatched from a mass of eggs on Sept. 23rd, 

 changed skin for the first time on Sept. 27th, again on 

 Oct. 6th, and a third time on 15th to 18th of October. 

 I noticed that all the larvae were not the same size. On 

 Oct. 29th some had begun to spin cocoons of a loose 

 web-like character, singly and gregariously in the 

 corners of the cage. Nov. 5th : Most of the larvffi had 

 spun cocoons on this date, and by Nov. 11th almost 

 every one had done so. The cocoons are soft silken 

 bags formed under surface of earth, but close to it, and 

 with particles of clay adherent to them. 



Pupae with small caudal spine. Male smaller than 

 female, and distinguished by its larger antenna-cases. 



The imagines, when touched, fall down and simulate 

 death. General colour white, with black oblong patch 

 at centre of primaries. 



Male smaller than female, with large doubly-plumed 

 antennae. In the female the antennae are smaller, but 

 otherwise resemble those of male. The extremity of 

 female abdomen is also furnished with a large mass of 

 silky down, absent in the male, and used to clothe the 

 egg-masses after deposit on twigs of the food-plant. In 

 the female the mouth is rudimentary ; I could find no
