APPENDIX 11 345 



DECEMBER 



Oiitdoor work is now at a minimum. Tlie weatlier is too severe, 

 as a rule, to allow pupa digging to be carried on with either success 

 or comfort, but favourable opportunities should be seized for this 

 employment as well as for ova collecting. 



Now and again we may meet with P. Populi at rest by day, or 

 fluttering round a light at night. Brumata and Defoliaria inay 

 also be seen, and the Early ]\Ioth (Bupicaiyraria) may appear on 

 the wing before the new year ; but nothing is likely to be met with 

 beyond these save the hybernators, already named in other lists, 

 and some of the Tlnecc. 



It is a good plan to utilise your spare time during the dreary 

 months of winter by attending to your cabinet. Rearrange your 

 specimens where neceFsary, and see that all are properly labelled ; 

 remove all greasy specimens, and deal with them as recommended 

 on page 127 ; also renew the supply of camphor or naphthaline in 

 yoiu' drawers and store boxes. Time may also be found for the 

 constnrction of apparatus that is likely to be required next season, 

 and for repairing anj' that has been damaged during the work of 

 the last.
