dragon-fly Enallagma cyathigevum, Charp, with one stigma 

 missing and aberrant neuration of tip of same wing. 



Mr. Kemp exhibited a collection of the genus Donacia, 

 consisting of about 280 specimens and comprising sixteen 

 species. He called particular attention to the long series of 

 D. discolor, showing great variation in colour, and also 

 pointed out the empty cocoons of D. vulgaris, showing the 

 small perforation which communicates with the intercellular 

 air-spaces of the root to which it is attached, and through 

 which the beetle breathes. 



Mr. Berthoud, of Hamel, West Australia, sent a large 

 number of wild flowers from " the Bush," which were 

 exceedingly beautiful and interesting. He had read a short 

 notice of the Society in the " Review of Reviews." 



Mr. Kaye exhibited examples oi Aniorpha anstauti, a giant 

 form of A. popiili, and of Smerinthus atlanticus, a giant form 

 of 5. ocellatus, both from North Africa ; together with the 

 hybrid metis obtained from a crossing of Amorpha anstauti 

 (male) and Smerinthus atlanticus (female) ; and also the hybrid 

 hybridus obtained from a crossing oi Smerinthus ocellatus (male) 

 and Amorpha populi (female). Both hybrids showed the male 

 to be prepotent. It was remarked that it was extraordinary 

 that metis, the equivalent of the inverse of hybridus, should be 

 more frequently obtained when the actual inverse of hybridus, 

 i. e. a pairing of male Amorpha populi and female Smerinthus 

 ocellatus, should be so exceptional and rare.
