 ggRACTICAL HINTS. 



~ By W. HOLLAND. 



{a) Get the men who are potato digging in market gardens, to look 

 out for large pupte for you, and you will sometimes have a number of 

 Acherontia atropos brought you. 



(jb) Do not fail to put on sugar every possible night now for Dasy- 

 cainpa riibiginea. It would probably be heard of in many more districts, 

 if collectors did not give up the sugaring too early. A good, place to 

 try is in or near an oak wood. If ivy is not near or convenient to 

 search, cut off branches with blossom and place in favourable looking 

 spots, and it will double your chance. Even if you do not get ricbiginea, 

 other species as Xylina semibrunnca, X. petrificata, and X. rhizolitha, 

 Calocampa vefusta, C. exokta, Hoporina croceago and Cidaria psittacata 

 may be attracted sometimes till the end of November. 



(c) Examine stems of wild parsnip for larvae of Cotichylis dUucidana. 

 The white frass is conspicuous just above the lower nodes of the stem. 

 Cut off stems containing larvre into convenient lengths and place in 

 damp sand. 



{d) Beat thatch of old summer houses in gardens, and Alucita 

 polydactyla may be got in plenty. 



{e) Beginning to middle of November, search after dark in birch 

 plantations, and Hybernia awatitiaria and Cheimatobia boreata may be 

 found in large numbers at rest hanging from the twigs and branches and 

 also on the grass below. 



(/) From about the 6th to 20th of November, look out for Pacilo- 

 campa populi, Pefasia cassinea and Ptilophora plumigera at light. The 

 two first named rest on dark surfaces near the light (see Ent. Record^ 

 p. 20) ; cassinea is sometimes out a {Q\y! days earlier i\\z.n populi. 



(g) Beat hedges containing spindle for Pteroxia caudella before it 

 hybernates. 



(//) Far more pupge of Smerinthus tiiiie may be dug up at elm than 

 at lime trees, and now is the best time to get them. Close up to 

 tree only. 



(/) Pull off bark from willow trees and rough fences near, for 

 larvse of Apainea unanimis, which hide away early, you will sometimes 

 find pupae oi Ptilodoniis palpina when doing this.
