Mr. W. J. Kaye exhibited an unusually large spray of the 

 magnificent Orchid, Cattlcya labiata, having five flowers. Three 

 flowers are said to be the usual number in this country, even four 

 flowers are very rare ; no doubt the excess of sun-heat of the present 

 year had been the primary cause of the increased development of 

 the flowers. 



Mr. C. P. Pickett exhibited a cabinet draw^er containing Angerona 

 pnmaria showing the efl'ect of colour environment on the race, 

 which he had been breeding experimentally for the last fourteen 

 years. A brood of larviE was split up into several sections and fed 

 under various coloured muslins throughout their larval period. 

 Those fed under red vmdin produced some of the darkest banded 

 males, several being of a blackish chocolate, while the banded 

 females were of a rusty reddish chocolate. Those fed under pink 

 muslin produced some of the finest specimens reared, many of both 

 sexes showing a tendency for the bands to disappear. One pair 

 have only a slight trace of bands, and closely resemble the plain 

 form. The form jiickettaria came out strongly in this portion. 

 None of these approached in any way those fed under the red 

 muslin. Of those fed under an orani/e-i/ellow )iiiisli)i, all the 

 females had the ordinary yellow ground colour much deeper, 

 several being quite orange-yellow. The males were a deeper and 

 richer orange. Those fed under a cream wnslin ivith a green plaid 

 pattern stamped on it produced some of the most curious forms 

 bred. Several specimens have patches and bleached markings, 

 varying in size and on varying parts of the wings, and look as 

 though response to environment had produced them. As a whole 

 they are not at all rich in colour, but rather inclining to be dull. 

 Pairings have been taken from each brood to continue the 

 experiment next season. 



Mr. Pickett also exhibited the following series and aberrations : — 

 A series of Melanargia (jalathea bred from Folkestone larvte and fed 

 up in a greenhouse. Some of the females were extremely large, 

 one male had a deep black border around all the wings (near var. 

 prncida). Colias hijaie taken at Dover in August, one of the males 

 had the row of spots on the underside unusually prominent. Series 

 of A(jriades coridon^irom Dover, including numerous vars. and abs. 

 obsnleta, striata, minor, etc. Series of the same species from South 

 Cambridge, mcluding among other named forms var. seiiii-syni/rapha, 

 a very tine female form with the hindwings perfectly blue. Two 

 specimens had the undersides of a deep smoky shade over the 

 entire surface of the four wings. Another very striking form was
