414 Mr. Forsayeth on the life-history of 



silk to the ground. It spins a net on the leaf, partially 

 curling it up, and sometimes rolling it ; but as a general 

 rule the margins of the leaf are merely approximated, 

 nnd a cobweb-like net spun across from side to side, 

 beneath which the larva feeds on the internal parenchyma 

 of the leaf. A single larva will thus destroy several 

 leaves, and when the former are numerous the tree 

 which they infest soon presents a blasted appearance. 

 At the end of October and early in November I found a 

 second brood of these larvse on the same trees. 



The cocoon is of a dense leathery nature, and re- 

 sembles a flat brown seed. It is made under a thin net 

 of silk on one of the leaves inhabited by the larva, or in 

 its immediate proximity. 



This larva, in its appearance, habits, &c., seems to 

 me to present a strong resemblance to that of S copula 

 strenualis, a leaf-roller. I have not compared the 

 imagines, but I hazard the opinion that the life-history 

 of each indicates a closer relation than that at present 

 supposed to exist between them.

Larvae rare in this localit3\ Found on leaves of a 

 thorny shrub-like acacia, but having white bark. I only 

 obtained three specimens during the whole season ; they 

 are very beautifully marked. Ground colour a light 

 grass-green, with white spots and figures all over the 

 dorsum and sides, the most noticeable being of an 

 )( shape, and running along the centre line of back. At 

 the spot marked "A" in figure is a transverse bar of an 

 orange colour in the centre, and deep blue at each 

 extremity, but visible only when the larva is in motion. 

 The movement is semi-looping, and the habits of larva 

 somewhat similar to those of the loopers. Front legs 

 six, sienna-red colour ; prolegs eight, but front pair 

 much smaller than the remainder ; anal two. 



The pupa is formed in a cocoon of silk and clay under 

 the surface of the ground, not attached by caudal end, 

 and of a dull reddish brown colour, without any white 

 efflorescence. Body unarmed.
