Cabbage 'Worms— Ifm. C. Ilolmts, Ptattshmj, ilo. 

 — Tlic green worm which has been destroying the cab- 

 bage's lu your neighborliood, is in all probability the 

 larva of the Southern Cabbage butterfly {Pieris protu- 

 ..'i\r. Boisd.) At least we know that this is the most 

 common insect found on the cabbage in your locality; 

 liut as you describe it simply as a " green worm," we 

 cannot decide positively, because there are several other 

 worms of a green color which also attack that plant. 

 At Figure 37 a, wc represent the larva of the South-

 two other common butterflies belonging to the same 

 genus {Piei'ie], which at present attack the Cabbage in 

 dift'ercut parts of the United States One ot these, 

 knuwii as the Kape Butterfly {P/«« rajxe, Schrank), has 

 nf lale years been introduced from Europe, and has 

 he ill iaj)idly spreading westward from the Atlantic sea- 

 board, while the armies of the Colorado Potato Bug 

 have been marching in the opposite direction, towards 

 tfic sea . Thus, while there is every reason to believe 

 that we shall, in a few years' time, give to our Eastern 

 liretliroii the greatest and most destructive insect foe of 

 thf I'otato; they seem determined to pay us back in our 

 own coin , by sending forth into the West the greatest of 

 cabbage pests. The only known way to destroy these 

 Cabbage worms is to pick and kill them either by hand or 

 chicken-power, and to catch and kill the butterflies 

 which are constantly hovering over the plants during the 

 sinishiny days of summer and autumn .

Bad pacUing— y/. C. Beanhlee, PairusmlU, Ohio.— 

 The green larva, marked with brown at each end of its 

 body, and with a large round brown patch on the 

 middle of its back, and also with sprangling horns at 

 each extremity which sting like a nettle, is the Saddle- 

 back caterpillar (£'/H/);W;a j/iVwaZea, Fig. 30). It feeds 

 on a great variety of trees, besides Indian corn on 

 which you found it, and last year ue nul with it on

 to pack them in a pasteboard box, which always sufl'ers 

 the moisture to evaporate from it, it is making matters

 considered as an exceptional occurrence, and we should 

 advise you to encourage, rather than destroy these long-

Borer in Apple Twig— ff. 0. Bracl-eU, Luwrtncf. 

 Katuas. — The borer in the apple twig sent is not, as you 

 suppose, the larva of the .Vpple-twig Borer (Bostrichue 

 hkamlatus, Say), which bores into the twigs in the 

 beetle state only ; but is evidently the larva of some long- 

 horned beetle. It resembles in every respect the larva 

 of the Parallel Loughorn[ElaphidionparalUlum, Newni.), 

 which we have bred from both apple and plum twigs, and 

 it will in all probability produce that beetle. The hole 

 at the axis of the leaf-bud, which connects by a bur- 

 row through a side-shoot, with the main chamber in 

 the twig where rests the larva, was evidently made by 

 that larva while younger. The Parallel Longhorn 

 bears a very close resemblance to the Oak Pruner [E. 

 r/llosum, Fabr.), which you will find figured on page OS 

 of Harris's Injurious Insects.
