tomentosus was constantly of another form ; yet no one hitherto had doubted 

 the specific identity of the two forms. 



Mr. Butler recalled the fact that, on the same plant of golden-rod {SoUdago 

 mrgaured), larvse of Mamestra persicarise might often be found of three or four 

 different colours. 



Mr. Henry Moore had once found larvae of Eupithecia virgaureata feeding 

 on the petals of a crimson dahlia, and they assumed a crimson hue, in lieu of 

 the ordinary ochreous with sepia-coloured markings.

 Spanish wheat 10 cwt. of weevils had been screened, and these must have con-

 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,
