 the Balearic Isles. Brunner mentions that in 1866 pere- 

 grinum appeared in the Isle of Corfu, and that the N. y\frican 

 variety is always of a lemon-yellow colour, and that the 

 specimens from W. Africa and from Hindostan are tinged 

 with blood-red.

Weevils of Wheat. — Mr. J. Jenner Weir (on behalf of Mr. 

 James Yogan) exhibited specimens of grain attacked by 

 weevils: from 74 tons of Spanish wheat 10 cwt. of weevils 

 had been screened, and these must have consumed several 

 times their own weight of grain before arriving at maturity : 

 in August, 1868, some American maize was stored, weighing 

 145 tons; in August, 1869, this was found to be infested 

 with weevils, and 6 cwt. of the beetles were screened out; 

 in December 29 cwt. more were screened out, making a ton 

 and three-quarters in all. Specimens of the weevils were 

 exhibited, and in both cases the depredator proved to be the 

 rice-weevil, Calandra Oryzae, and not C. granaria : along with 

 the weevils were a {qw specimens of Stene ferruginea and of 

 a Laemophloeus, the predatory larva of the latter being the 

 natural enemy of the Calandra. Prof Westwood observed 

 that no description of the larva of Calandra granaria had 

 been published : it was comparatively a fatter and shorter 

 larva than Balaninus, distinguished from the usual form of 

 Curculionidous larvae by having two recurved points or 

 hooks at the extremity of the body, and changed to the 

 pupa within the grain. 



Argynnis Adippe and A. Niche. — Mr. J. J. Weir, with 

 reference to Mr. Butler's suggestion of the identity of Argynnis 

 Adi})pe and Niobe, exhibited four specimens which had been 

 sent to him from St. Petersburg, one as the typical form of 

 Adippe and another as its variety Cleodoxa, and one as the 

 typical form of Niobe and another as its variety Eris : the 

 typical form of each had silvery spots on the under side, and 

 these were absent both from Cleodoxa and Eris ; but notwith- 

 standing this parallelism of variation, there was no greater
