disturbance, and so much resembled the S. limonium 

 in colour, that it was only by searching for the plants 

 which showed signs of being eaten, that I was able to 

 find them. 



The larva, when full-fed, is about 8 lines long ; the 

 head is very small, and when the creature is at rest or 

 disturbed it is drawn under the second segment, 

 which is provided with two horn-like projections, and 

 covers the head like a cowl. The third segment is 

 the largest, and from this the body tapers gradually 

 to the anal extremity ; the last segment but one being 

 provided with a horn, as in the larvae of the Sj)liincji&%. 



The colour of the head is brownish-green, with six 

 small black spots (ocelli) on each cheek ; the head is 

 sparingly covered with pale obtuse setae ; the tips of 

 the horns are pink ; the body is bright green, shag- 

 reened with light and dark spots ; the anal segment is 

 green, with a ray of six long bristles, which point 

 backwards. 



When about to change to a pupa the larva crawls 

 to the top of the leaf, and spins across it numerous 

 silken threads, to which it attaches itself by the anal 

 claspers ; and in this position it remains about two 

 days. The colour gradually becomes brown, the skin 

 assuming a shrivelled appearance. 



The final change is gone through very suddenly ; a 

 few minutes suffice to throw off the old skin, which 

 remains in a little heap on the leaf, and the pupa then 

 hangs freely suspended by the anal segment (or 

 hooks ?). It is very attenuated, and the points of the 

 legs and wing-cases are free from the body. (Henry 

 Moncreaff, 19th May, 1871; Entom., June, 1871, V,
