NOTES AND OBSEBVATIONS. 



Acronycta tridens and psi. — With regard to the note on page 119 

 on the differentiation of tbese insects, is it not the fact that the 

 females can be distinguished by the colour of the hind wings, which 

 in tridens are grey, and in psi white ? It is so at least in my series, 

 all of which are bred ; but if I am wrong in this, I shall be glad to 

 be corrected. — (Rev.) W. Claxton ; Navestock Vicarage, Romford. 



CAPTUEES AND FIELD REPORTS. 



Halesus radiatus. — Mr. A. Sich was kind enough to give me a 

 specimen of this caddis-fly, taken at Chiswick on October 4th, 1903. 

 The record is of interest on account of the encroachment of bricks and 

 mortar over the neighbourhood. — W. J. Lucas ; 28, Knights Park, 

 Kingston-on-Thames, May 13th, 1907. 



Vanessa cardui. — On May 11th numbers were seen at Oxshott. 

 They were flying strongly, and usually more or less with the wind, 

 from a south-westerly direction. None were seen to settle, nor could 

 a capture be made. They gave one the impression that they formed 

 part of a migration. — W. J. Lucas ; 28, Knights Park, Kingston-on- 

 Thames, May 13th, 1907. 



Cyaniris argiolus in North-west London. — I should like to record 

 the fact that I saw a specimen of C. argiolus, L., in the garden here, 

 to-day. It was flying in the bright sunshine, and appeared in fine 

 condition, probably having just emerged. It has been observed here 

 in May and July most years since 1899, and seems to have become 

 firmly established. It is the only " blue " we ever see here. —

 Loudon, N.W., May 11th, 1907. 



Scarcity of Larvae in Season 1907. — I notice in the reports of 

 the City of London Entomological Society in the May 'Entomologist ' 

 that Mr. L. W. Newman comments on the scarcity of the larvse of
