110 POLYOMMATUS (lTOJINA) ADONIS. 



tliis larva was so like those I had lately reared that 

 I felt quite puzzled. It luckily happened that Mr. 

 Buckler and I had just been comparing the notes we 

 had made of Adonis, and so, seeing in this larva all 

 that I had seen in Adonis, except that its bristles were 

 brown instead of black, I sent it on to him at once, 

 drawing his attention to a little point which I had 

 wished him to notice in Adonis. Thus with every 

 incentive to exactness, he examined and figured it 

 most carefully, finding nothing to notice but the tint 

 of the ground colour and the hue of its hairs, and then 

 kept it apart, waiting to see what the imago would 

 prove to be, till on the 31st of July there appeared a 

 fine Gory don. 



As far, therefore, as our means of comparison have 

 gone — our materials to work upon being some dozen 

 and a half larvse of Adonis on the one hand, and this 

 one larva of Cory don, and figures of others taken in 

 1862 on the other — we can say that the two species 

 resemble each other in the larval state in every par- 

 ticular of form and ornamentation except these two 

 points : 



Adonis has its ground colour deeper green, with the 

 hairs or bristles black, while Cory don has the ground 

 colour of a lighter, brighter green (a green with more 

 yellow in its composition), and the hairs light brown. 



I have been thus minutely circumstantial in relating 

 what was done by us because the result we have 

 arrived at is not altogether in agreement with what 

 we have been able to find already published. Thus, 

 in ' Stainton's Manual' there are descriptions from 

 Freyer, which, according to our observations, rightly 

 distinguished between the green of Cory don and the 

 deep green of Adonis, but err in making the number of 

 yellow dorsal streaks different, for Adonis certainly 

 has but eight in a row, and not twelve. 



The only other author accessible to us, Boisduval, 

 speaks of " le grand rapport qu'il y a entre cette 

 chenille (Cory don) et celle d! Adonis" and gives every
