these already formed limbs complete their development, and 

 become clothed with scales. It will also be more easily under- 

 stood how cripples occur, for if the limbs, whilst in their free 

 state, should by any accident become slightly misplaced, con- 

 torted, or maimed, they would become cemented in that condition 

 by the hardening over them of the exuded " lac." Therefore it is 

 probable that the setting of the j)upa-case is the most critical 

 point in the insect's existence. 



As there was no trace whatever of scales, as such it would be 

 interesting to know how and when their development took place, 

 and to what causes variations in their form of colour and 

 arrangement may be attributed. It would appear probable that, 

 " cetera paribus,'' the effect of light upon the exposed surface of 

 the rapidly maturing wings would cause certain results as to 

 colour.

ENTOMOLOGICAL NOTES, CAPTURES, &c. 



Thecla W-album. — As one of the founders of the South 

 London Entomological Society, I am surprised to find the 

 secretary not knowing that the larvifi of Thecla W-album are 

 cannibals, as I have stated before that Society several times that 

 such was the case. I have bred it for several 3'ears, but never put 

 them together until they attain the pupse state, otherwise I found 

 some of them thriving remarkably well on others which were 

 getting beautifully less. — C. J. Boden ; 153, Snowsfields, South- 

 wark, July 4, 1881. 



Larv^ of Genus Thecla. — As regards the larvae of the genus 

 Thecla being cannibals, I beg to say that I have noticed it this 

 year for the first time in T. Quercus. I found eight larvae on 

 May 31st (in Hampshire) nearly full grown. A few days after, I 

 saw one larva which was preparing to "pupate" being eaten by 

 three others. They were well supplied with fresh oak-leaves 

 twice a day. I did not separate them afterwards, but there was 

 no more cannibalism. — M. S. Jenkyns ; Kiverside, East Molesey, 

 July 12, 1881. 



Apatura Iris var. Iole. — I have taken this season numerous 

 specimens of Apatura Iris in our county. Amongst them is a
