POLYOMMATUS (lYCTENa) ADONIS. 109 



riclge above. In some specimens the ventral prolegs 

 are also marked with yellow; the spiracles are con- 

 spicuous, being round and black ; the pulsating dorsal 

 vessel is rather deeper green- than the ground colour. 



Some of my larvae buried themselves about half an 

 inch deep in the loose soil, and formed a weak sort of 

 cocoon ; others, not having been supplied with soil 

 that could be easily penetrated, retired under the 

 stems of their food-plants, and in angles formed by 

 the branching stems spun a few weak threads to keep 

 themselves in place. 



The pupa is barely half an inch long, dumpy in 

 figure; the profile of the back swells out at the 

 thorax, drops in again at the waist, and the abdomen 

 slopes off in a curve to the rounded anal end ; the 

 ventral profile is much straighter, though still with a 

 slight curve ; the wing-cases reach more than two- 

 thirds of the whole length, and the widest part is just 

 where they end. The thorax and wing-cases are 

 slightly glossy, the abdomen granulated ; there are 

 some very small hairs scattered all over ; the colour 

 is at first greenish on the wing-cases, greenish-brown 

 on the rest of the body ; afterwards ochreous all over, 

 and. finally turning very dark the day before the imago 

 emerges. 



On comparing the larvae of Adonis, which I had sent 

 him, with figures of Gory don made some years ago, 

 Mr. Buckler could detect no point of difference except 

 a somewhat different tint in the green ground colour ; 

 this made us very anxious to see the larva of Gory don 

 again, and our wish was very soon gratified in an 

 unexpected manner. 



My friend had sent me a great many plants of Hvp- 

 jpocrepis comosa for my larvae, and upon one of these 

 that had not been wanted for their use, I found on 

 June 8th, a half-grown Lyccena larva, which had evi- 

 dently travelled to me out of Hampshire with its food. 



I had been told that Gory don occurred at the place 

 whence the plants were procured, but not Adonis, yet
