 latter should be cut off before the fly emerges. 



CaterpiNars— The larva? of a number of moths, 

 most of which have been described elsewhere in this 

 volume, infest the rose, and often do considerable injury 

 to the foliage, etc. The chief culprits are the Vapourer 

 Moth (Orgyia antiqua). Pale Tussock Moth (Dasychira 

 pudibunda), Gold-tail Moth (Porthesia similis), Brown- 

 tail Moth (Euproctus chrysorrhoea), Buff-tip Moth (Py- 

 gaera bucephala), Dagger Moth (Acronycta psi). Winter 

 Moth (Cheimatobia l)rumata), Mottled Umber Moth 

 (Hybernia defoliaria), lied liose Maggot (Pardioe tripunc- 

 tata), Brown Eose Grub (Spilonata roborana), Green Rose 

 Maggot (Tortrix ribeana), Yellow Rose Grub (Croesia 

 holmiana), and the Rose-leaf Miner (Nepticula anoma- 

 lella). The Red Rose Maggots spin the leaves together 

 and feed upon them and the buds. The Brown Rose and 

 the Green Rose Maggot do the same thing. The Leaf 

 Miner forms tunnels in the leaves, and the rest feed on 

 the foliage generally. 



Remedies. — During the spring and summer the rosarian 

 must be constantly on the alert looking out for cater- 

 pillars, and remove them by hand. In the case of those 

 caterpillars that roll the leaflets together, it is almost 

 impossible to reach them by means of insecticides; hand- 

 picking is therefore the only remedy. A vigorous shaking 

 of the bushes will cause many of the caterpillars to fall 

 to the ground, but, unless a sheet or sack be placed under- 

 neath to catch them, they will crawl up the stems again 

 and do fui'ther mischief. Spraying with Formula^ Nns. 

 10 or 11 will destroy all the foregoing larvjie. 



Chafer Beetles.— Three beetles, in addition to the 

 Rose Beetle just described, also attack roses. The Com- 

 mon Cockchafer Beetle (Melolontha vulgaris), also known 

 as the May Bug, feeds on the leaves and petals, and their 

 lai'ge, fat, white gi'ubs frequently eat the roots of tender
