J^RACTICAL HINTS. 



Field Work for July and August. 



By J. W. TUTT, F.E.S. 



1. — The larvfe of Eupithccia cenosata are to be found in seeds of 

 Silene infiata, in July, those of Eupithecia linariata in seeds of Linaria 

 vulymis, in July and August, those of Eupithecia pulcJwllata in flowers 

 of Diyitalis pitrpuralis, in July and August, those of Eupithecia 

 plwaheolata on flowers of Melainpyruiii pratense, in July and August. 



2. — The larvfe of Eupithecia valerianata feed on' flowers of 

 Valeriana oJficinali>i in July. 



3. — The fullfed larvae of Aiiarta inyrtilli may be SAvept from 

 L'alluna vulyaris in July and again in September (Newman). 



4. — The larvte of Malacosoma castrensis can be reared readily on 

 chrysanthemums ; cover a plant with a muslin net, leave them until 

 they spin up, then clip oft' ihe cocoons and put in a breeding-cage 

 (Button). 



5. — The imagines of Acidalia etuutaria fly most freely at dusk, 

 and may be found almost throughout June and July ; there are two 

 distinct broods (June and x'^.ugust) in the Isle of Wight, in the marshes 

 fringing the Yar. 



6. — The larva? of Xylina >>eiiiihrun.nea are to be found on willow 

 and ash in July (Croydon and Hackney Marshes) (Machin). 



7. — The plants of Typha latifolia, with yellow central leaf, want 

 cutting down in August for larva? of Xonayria arundinia. 



8. — The larvie of Eupithecia isoyrammata are to be found in flowers 

 of Clematis vitalba in August ; a little black spot distinguishes the 

 aftected flowers. 



9. — The larva? of Eupithecia piuipinellata feed on seeds of Pinipi- 

 nella saxifraya in August and September. 



10. — The larvas of Eupithecia subnotata feed on the flowers and 

 seeds of Chenopodium in August and September. 



11. — Larvfe of Eudidia mi occur on sandhills feeding on sea 

 marram-grass ; drop oft' when disturbed and twist into grotesque 

 attitudes and feign death ; the white mottled colour and shape exactly 

 imitates the exuviae of snails {Helix neuioralix) (Kane).
