Viii PROCEEDINGS OF THE ROYAL HORTICULTURAL SOCIETY. 



Mr. McLachlan pointed out that the proposed trap to be 

 affixed to the lamp-posts, in the case of suburban fruit planta- 

 tions, would be practically useless, as only the male insects 

 would be thus captured, the females being nearly destitute of 

 wings, and incapable of flight. All attempts at stamping out the 

 winter moth should be directed fco the destruction of the females, 

 which are capable of depositing eggs for many generations in 

 succession without the intervention of the male. The capture 

 of myriads of males would not have the slightest appreciable 

 effect on the fertility of the untrapped females. 



Monstrous Cypripediums. — Dr. Masters showed drawings of 

 two Cypripedia, in one of which the three sepals were separate, 

 as in most Orchids, whilst in the others there was an adhesion 

 between the median sepal, the lateral petal on the left side, and 

 the lateral sepal on the same side, the adhesion of these parts 

 being accompanied by corresponding adhesion of the labellum to 

 the right lateral petal. The median stigma, G, 1, of the Dar- 

 winian notation, was also petaloid. 



Keteleeria Davidiana. — Dr. Masters showed a cone sent by 

 Dr. Henry to Kew, from Ichang, which has special interest 

 as being intermediate in character between the Spruces (Picea) 

 and the Silver Firs (Abies). It is congeneric with Keteleeria 

 Fortunei, a tree introduced to this country from China, but which 

 is too tender for general cultivation.
