XeiU>caterpillar of the Forest — A. M. Brown, 

 Villa Riige, Ills. — The worms wliicli have infested your 

 plum, api^le, and several forest trees, are the above 

 named insect [CUsiocampa syhat ica , Harris). It hatclies 

 at about the same time of year as does the common 

 Orchard Tent-caterpillar (CT. americana), matures at the 

 same time, and spins a cocoon almost identically similar; 

 but besides the difference iii the markings mentioned 

 on page 208 of our llrst volume, it differs from the other 

 species in the following essential points : It is a more 

 indiscriminate feeder, attacking alike many forest as 

 well as orchard trees, and is more apt to become exces- 

 sively numerous in certain years, and to swarni like the 

 Army-worm, wherefore it has been erroneously called 

 THE Anny-worm in some parts of New York. It spins 

 a much less conspicuous web (sometimes fastened to 

 the limbs so closely that it is not readily perceptible) 

 and congregates on the outside of it, especially at the 

 dilferent moulting periods, when Uu-go companies may 

 often be found huddled together, and easily destroyed. 

 It loses its gregarious habit much earlier, or when about 

 half grown, and travels rapidly from place to place in 

 searcli of proper shelter to spin its cocoon. Its egg mass 

 is of a uniform thickness, and is dopked oft" si|uarely at 

 each end . 



Jolm H. Eiians, Pes Arc, Arl:.— The worms which arc 

 scattered all over your x)art of the country, and which 

 completely stripped the over-cup timber in the over- 

 flowed bottoms, both last year and this, are the same 

 Forest Caterpillars mentioned above. As they have 

 been very numerous this season, \ve have concluded to 

 publish a more full account of tliem in our next issue. 

 Your informant, in stating that this worm also devours 

 the Cotton plant, must, we think, have confounded it 

 with the Cotton- worm {Aiiomis xylina, Say). 



Worm boring into Peach — W. G. Flagg, Alton, 

 Ills. — The pale green worm, with cream-colored specks, 

 and a broad cream-colored lateral band, and which you 

 found inside a peach, produces an undescribed moth, 

 of an ash-gray color, belonging to the genus Xylina. 

 Wc have for several years been aciiuainted with this 

 worm, and have foiuid it in ajiplcs, peaches, oak-galls, 

 on hickory leaves, and on other forest trees. It has 

 never done miu'h damage to fruit. AVe shall shortly 

 figure the moth. 



A 0. Hammond, Warsaii; Ills. — The worm boriug 

 into your apphis is the siinie as that mentioned above. 



M. M. Ilooton, Centralia, Jlls. — You will also recognize 

 him as the gentleman boring into your peaches. 



Insects Named — A. Engelman, Shiluh, Ills. — The 

 two tree-hoppers which you found together on one of 

 your vines, are not of the same species. The golden- 

 green species with the back compressed, thin-edged, 

 rounded, high and arched anteriorily, like the edge of 

 a shoe-knife, may be known as the (ioldcn-green Vine 

 Hopper {.Smilia auricnlata, Fitch). The brown species 

 with a camel-like hump on his back is the Membracis 

 ampelopsidis of Ilai-ris. Both species are common on 

 grape-vines. The rough beetle is $ Trox punctatus. 



L,ice ou " Snow-balls''— Jfr*. C. L. Seymour, 

 Chicago, Ills.— Gi\e your shrubs frequent syringiugs of 

 tobacco-water, or of a weak solution of crcsylic soap, 

 especially when the lice first appear.

Twig Borer- S. H. Kriedelbaugh, M. />.— The in- 

 sects which were boring into your grape cuttings, and 

 [Fig 154] which entered at the axil of a bud, 

 are the conuuon Twig -borer (i?6«- 

 trichus hicaudatus, Say), repeatedly 

 referred to in back numl)crs under 

 this name. We repeat the annexed 

 r c cut (Fig. iri4), & giving a side view of 

 (J, and (i aback view of $. We found 

 a (f and 2 i" each of the cuttings you sent. 



G. F. Merriam, Topela, Kansas. —\ovlIl insect boring 

 grape canes is the same Twig-bonT. It is an old enemy. 



Preserving and Mounting Beetles — G. C.P., 



Lawrence, AaH»a«.— Beetles to be sent away can be well 

 kept in alcohol. Entomological puis can be obtained in 

 riuladelpbia, as per advertisement on our cover. Be 

 sure and order the Klaeger pin, made in Berlin; else 

 they will send you a worthless pjn of American make, 

 which in quality, strength and finish is as inferior to the 

 geiniine I^-ussian article as a squash is to a pine-apple 

 in llavor. 



Bee Uneniy — /'. Brewer, Wayuesrille, J/w. — The in- 

 sect which you sent and ^vliich you caught with a Ijcc, 

 is not the same Dee-enemy which you sent last fall, and 

 which we referred to on page 50. That which you 

 now send is the Spotted Kove-bectle {Staphilinus macu- 

 losus, Grv.), an Insect of scavenger habits, and which 

 would be more likely to de\our a dead than a li\ing 

 bee. 



Orange Raspberry Rust — Isidor Bush, Bushhcrg, 

 .]/,, —The bright orange rust which is entirely covering 

 (he underside of the leaves of many of your raspbcny 

 bushes, is the Orange Raspberry Rust {Credo niborum). 

 Knowing that you have the back numbers of our maga- 

 zine, we refer you to what was said about this fungus 

 on page iot* of our first volume. There is no other 

 available remedy than the complete destruction, root 

 and branch, of every iulected plant, and unless this 

 remedy be unhesitatingly and thoroughly applied, you 

 may expect in a few years to lose your whole raspberry 

 plantation. Several other subscribers have lately sent 

 to us this same lungus, which seems to be on the 

 increase. This answer will suffice for all.

 Iowa.—\on will find the information you w.ant on page
