PRACTICAL HINTS. 167 



campion for larva? of Dianthoecia capdyicola ; the larvae often have their 

 bodies hanging half-way out, and round holes in the capsules denote 

 the affected ones. 



11. — During the first fortnight of July visitors to the south-west 

 coast (Lizard, &c.) shonld look ont ior Sesia pJnlantMf()rmi!< Ajing along 

 the flowery earth-walls, and settling on the thyme and seathrift. -S'. 

 ichneiiHionifoninft is also there at the same time. Both fly in the 

 bright sunshine, and prefer the morning sun. 



12. — At the end of July collect the seedheads of the common 

 blue-bell (Scilla nutans) for larvas of Kujioccilia maculomna. It is 

 necessary to open the seed-vessels to find them, as the larvae give no 

 outward indication of their presence. 



13. ^In July and August collect the flower-heads of Centaurea 

 scabiosa on the coast between Deal and St. Margaret's Bay. Keep in 

 band-box, and you will breed plenty of ('(inchi/lu alternana. 



14. — The larva of ('onclnjlis Htminineana feeds in July, and again in 

 September at the base of the flower heads of Centaurea nif/ra, eating 

 the young seeds, and lying curved in the cavity formed, or (if disturbed) 

 retreating into the stem (Barrett). 



15. — The larva of Eupoecilia atricapitana feeds in July (second 

 brood) within the growing stems of- Senecio jacohacae, eating the pith 

 and stopping the growth of the central shoot so that it becomes 

 thickened and covered with a bunch of leaves, while the side- shoots 

 grow lip past it (Barrett). 



16. — The green, semitransparent larva of Gracilaria populetoriuit 

 feeds in July, making a cone of an entire birch leaf. 



17. — The green larva of Depressaria capreolella feeds in July, in the 

 leaves on the higher shoots of Pimpinclla mxifrar/a. 



18. — The larvae of EujntJtecia venosata feed during July inside the 

 capsules of Silene, much in the same manner as the Dianthoecias. 



19. — In July the imagines of Collix sparaata (York, Wicken, New 

 Forest, &c.), swarm at early dusk, flying about the buckthorn bushes 

 with Scotosia rhamnata. 



20.- — The imagines of Epionc apiciaria always used to occur in 

 abundance late at night (11 p.m. -12 p.m.) round sallow bushes in 

 Wicken, in late July and early August. We used often to make up a 

 bag with this species on the way home. 



21. — During July and August be sure to fill a linen bag or two 

 with capsules of Silene. They should be transferred to band-boxes 

 later. 



22. — From solitary floAver heads of foxglove in open spaces in woods, 

 the larvae of Eupithecia pidcJwllata may be obtained in the spun up 

 flowers in July. 



23.^ — After a dry, hot day in July, if there be the slightest trace of 

 dew, Nndaria senex may be found in its marshy haunts, just before 

 dusk, swarming. We have seen them in hundreds crawling up 

 the grass and rushes, then fluttering off, threading their way 

 among grass and rushes for about half an hour. After that their 

 flight is over, 



24. — On rough heath-covered ground at a moderate elevation 

 where there is an abiindance of bare rocks Danydia nbfiiscata is found 

 in July, resting on the lee side of the rocks, and creeping into the 

 shelter of any overhanging part.
