also taken in Essex, viz., by Mr. B. Harwood, at St. Osyth, 

 on August 21st, 1899 ; (3) a series of males of Cordulia 

 cenea, ranging in date from June 5th to July 1st. These 

 specimens are unusually large, the smallest of them 

 measuring 49*5 mm. in length, and 71 mm. in expanse of 

 hind wings, and the largest 53*5 mm. by 72 mm. 



Mr. Lucas, to illustrate the exhibit of Messrs. Campion, 

 showed a <5 S. vulgatum taken in Richmond Park ; two 

 c?s from Denmark; and three c?s S. striolatum, for com- 

 parison. Drawings were shown of S genitalia beneath 

 segment 2 of both species, and a photo-micrograph of the 

 genitalia, etc., of 5. striolatum. 



Messrs. Harrison and Main exhibited (1) a brood oi Pier is 

 brassicce, bred from ova obtained from a normal female taken 

 near Liverpool ; 38 pupae were produced, from which 36 

 butterflies emerged in the summer ; the remaining 2 pupae 

 are lying over the winter. On the under-surfaces of 3 of the 

 males, and on both upper and under-surfaces of 10 of the 

 females, in the space between the black spots on the fore 

 wings, there are black scales, varying in number. In some 

 specimens they are just perceptible, increasing in others, 

 until, in the most extreme form, they constitute, with the 

 spots, a broad, black band ; (2) Aplecta nebulosa ; a series 

 from Delamere Forest, bred this year from collected larvae — 

 varying from the usual grey colour to the almost black form, 

 with deep white fringes and crenulate border. For com- 

 parison were shown series from the New Forest, bred from 

 the egg, and from Epping Forest, from collected larvae. 

 These exhibited little variation, the New Forest specimens 

 being of the usual light form, and the Epping Forest insects 

 were, as found in former years, similar to the grey form from 

 Delamere ; (3) Tcphrosia biundidaria, a bred series from the 

 New Forest, of the common light colour, and a series of the 

 dark brown form from Delamere, some of the latter being of 

 an intermediate shade. 



Mr. Kaye exhibited an extremely large ? specimen of 

 Apatura iris, caught in the New Forest, on July 23rd, 1906, 

 measuring 3-^ in., i.e., \^ in. more in expanse than the 

 extreme size given by Mr. C. G. Barrett in his " British 

 Lepidoptera." It was stated that no bred specimen ever 

 attained such size. 



Mr. Dobson exhibited four species of the genus Sympetrum, 

 all taken in one place in Surrey, on September 3rd, 1906, as 

 follows : S. striolatum ; S. flaveolum — of which he took twenty 

 examples; S. sanguincum ; and S. scoticum ; he also showed
