Mr. A. A. W. Buckstone exhibited several series of Selenia Imuiria

Failed in an attempt to force pupa^ in summer, but fourteen 

 moths emerged under natural conditions. There are 46 pupae 

 remaining over. 



D. Dwarfed specimen bred from a full fed larva taken at Box 

 Hill in September. Moth emerged in the following May. 



He communicated the following note : — 



" Both the type and a much darker form occur in the Teesdale 

 district (on Yorkshire and Durham side). Some of the specimens 

 shown at B and C would appear to approach ab. stMunaria. 



" It is usual for the pup;c of the second (summer) brood to remain 

 green, but those which produced the moths which emerged October 

 to December (C) were brown, as are those which have yet to emerge. 

 The moths themselves are, speaking generally, considerably darker 

 than the April-June specimens, instead of being lighter as those of 

 the second (summer) brood almost invariably are. These two 

 peculiarities, together with the fact that the moths commenced to 

 emerge only after the pupie had been subjected to frost, cause me to 

 consider them rather as precocious members of the usual spring 

 emergence. 



" Specimens exhibited varied from greyish through various shades 

 of brown to red-brown, thickly sprinkled with red scabs." 



Mr. Bowman exhibited a short series of Zunosonia {/■!/>}ii/r(i) pendu- 

 laria, and communicated the following notes : — 



" 1. Examples, in which the pink suffusion on the forewings is
