weeks, till fully grown, then escapes and lets itself down 

 to the ground by means of a silken thread. Sometimes 

 the injuries caused by the caterpillar cause the fruit to 

 fall off, and then the caterpillar easily crawls out on to 

 the ground. Directly the caterpillar leaves the fruit it 

 crawls along to the nearest tree and ascends it, finds its 

 way into the first crack or crevice, .and surrounds itself 

 with a silken case gummed over with a sticky fluid. Here 

 it remains till the spring, when it appears as a perfect 

 insect in May. 



Remedies. — (1) Pick up and burn all fruit that has fallen 

 early on the ground, and that shows evidence of being 

 worm-eaten. (2) Grease-band the trunks, as advised in 

 the remedies for the Winter Moth, taking special care to 

 see the grease paper is kept thoroughly moist and fre- 

 quently smeared with the grease. This smearing must be 

 continued during May and June, and into the early part 

 of July; then the caterpillars, which have let themselves 

 down from the fruit, when they try to ascend the trunks 

 will be easily caught. (3) Spray the trees directly the 

 petals fall with Paris Green solution or Lead Areenate 

 Spray solution (Nos. 10 and 11). This will destroy any 

 eggs that may have been laid upon the young fruit ; repeat 

 the spraying a fortnight later. (4) All dead rubbish, etc., 

 that may have accumulated underneath the trees should 

 be carefully gathered and burnt, so as to prevent the pos- 

 sibihty of any larvae or pupae escaping. (5) Wrap a hay- 

 band, or strips of old sacking, around the trunk of each 

 tree early in June; let this remain till winter; then re- 

 move and burn. The hay will serve as a trap for the 

 larvae or pup«. 



Figure-of-Eig-ht Moth (Diloba caeruleocephala). — 

 The larvte of this moth, commonly known as the Blue- 

 head Caterpillar, occasionally does injury to the foliage of 

 the apple and plum. The parent measures about one
