PRACTICAL HINTS. 295 



2. — The dry friable turfs, collected in the corners at the roots of oak, 

 should be well searched, as well as the corners themselves, for cocoons 

 of Dnjmonia chaonia and dodonea. Run your hand along the trunk 

 carefully for adherent cocoons. 



3. — Almost all the Cymatophora ocularis in collections are bred from 

 pupae which are found spun up at the roots of various kinds of poplars^ 

 The pupae of Taeniocampa popideti are to be found deep down at the 

 roots of the same trees. 



4. — The pupffi of all the Taeniocampids should be dug for in 

 November. A detached tree usually gives much better results than 

 those growing close together. 



5. — In November, and on through the winter, the conspicuous 

 yellow cocoon of J^asi/cJn'ra pudibnnda is easily found among the loose 

 rubbish collected about the roots of various trees, or under loose bark. 



6. — The cocoon of Lkinas con/li may be found, sometimes plenti- 

 fully, under moss, at the roots of beech trees, very rarely on the trunk,, 

 from October on through the winter. 



7. — The black cocoon of Poecilocampa populi is to be found in 

 October and November, firmly glued to the inside of a piece of loose 

 bark, or spun ixp tightly among decayed leaves near the base of the tree. 



8. — In October and November, work round the roots of willows, 

 on the banks of ditches and streams, on the side nearest the water ; 

 the sods there should be shaken, and the cocoons of Leiocampa 

 dictaea and of Ftilodontis palpina will be found done up among the dry 

 roots. 



9. — The pupa of Ewj/mene dolobraria is to be found by loosening the 

 edge of patches of moss on beech and oak trees, in November. 



10. — The pupa of EnpitJu'cia dodoncata may be found through 

 the winter months under loose bark on hawthorn trees. 



11. — November is the month to find the weak cocoon of Loplio- 

 pteryx canielina, under moss, on oak, beech, elm, etc. 



12. — Turn over stone-heaps, etc., in November, for Dasypolia 

 templi, a widely distributed insect in the north, but retiring in its 

 habits. Where stone walls are made from flat stones, the latter are 

 often allowed to lie about in heaps, and by turning them over, one or 

 two D. templi may be found in every heap (Robson). 



::^OTES ON COLLECTING, Etc. 



Notes from Beoxbouene. — The members of the North London 

 Natural History Society visited Broxbourne on July 3rd, 1897, 

 arriving there, via Liverpool Street, at about 2.45 p.m. The party 

 made its way, by a rather circuitous route, to " The Woodman," 

 Wormley West End. Messrs. Fuller and Garland found the larvas of 

 Eupithecia renosata by the side of the path, in the pods of Silene 

 inflata. Soon afterwards Mr. Prout beat out a specimen of Acidnlia 

 interjectaria. As the party proceeded, it became evident that certain 

 Geometrids were to be had by beating, mostly Acidalia aversata, 

 Lareniia didymata, and Cidaria Julvata, but including some beautiful 

 little specimens of Melanthia bicolorata, just out. Three specimens of 

 Cucidlia umbratica were taken on fences ; and the larvae of Euchloe 

 cardaviines occurred not uncommonly on Cardamine pratensis, but 

 Zygaena trifolii was a total failure, not one being seen. The party 

 enjoyed a hearty tea at " The Woodman," at 6 p.m., and walked back
