Tent-caterpillar of the Forest— .-1. M. Brown, 

 Villa Ridge, IlU.—Tlie worms which have infested your 

 plum, apple, and several forest trees, are the above 

 named insect ( Clisiocampa ayhutica , Harris). It hatches 

 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 in the markings mentioned 

 on page 208 of our tirst volume, it differs ft'om 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 swarm like the 

 Army-worm, wherefore it has been erroneously called 

 THE Ai-my-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 

 different moulting periods, when large 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 

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

 is of a uniform thickness, and is docked off s(|uarely at 

 each end. 



John, E. Evans, Des Arc, Arl-.—Thv worms which are 

 scattered all over your part 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, we have concluded to 

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

 Your infoi-maut, in stating that this worm also devours 

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

 with the Cotton-worm {Anomis xtjlina,, Say). 



iVorm boring: into Peach— W. C. 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, prodvices an undescribed moth, 

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

 We have for several years been acquainted with this 

 worm, and have found it in apples, peaches, oak-galls, 

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

 never done much dama.gc to fruit. We shall shortly 

 figure the moth^ 



A 0. Hammond, Warsaw, Ills.— The wonn boring 

 into your apples is the same as that mentioned above. 



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

 him as the gentleman boring into your peaches. 



Insects Nanieil— >-f. Engelinan, Shiloh, Ills. — The 

 two treu-lioppers which you foiuul 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-lmife, may be known as the Golden-green Vine 

 \lof-pe(%Smilia anriciilaia. Fitch). The browi species 

 with a camel-like hump on his back is theXilemiracis 

 ampelopsidis of Hams. Both species are common on 

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



Ijice on " Snonr-balls'' — Mrs. (J. Z. Seymour, 

 Chicago, His. — Give your shrubs frequent syringings of 

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

 especially when the lice first appear.

Tivi^ Borer- .y. //. Kriedelbaugh, M. D.—T\\e in- 

 sects which were boring into your grape cuttings, and 



[Fig. 154 ] 



which entered at the axil of a bud, 

 are the common Twig -borer {Bos- 

 T\rV HH 1 *'*^"* Ucaudatus, Say), repeatedly 

 referral to in back numbers under 

 this name. We repeat the annexed 

 cut (Fig. 154), 5 giving a side view of 

 '^'"c^ior-Brownr'' (f", and G a back view of ? . We foiuul 

 a c? and $ in each of the cuttings you sent. 



G. F. Merriam, Topela, Kansas. —Yoxxv insect boring 

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

 Preserving: and mounting Beetles— ff. C. B., 

 Lawrence, Kansas .—BvetXes to be sent away can be well 

 kept in alcohol. Entomological puis can be obtained in 

 Philadelphia, as per advertisement on our cover. Be 

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

 they will send you a worthless pin of American make, 

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

 genuine Prussian article as a squash is to a pine-apple 

 in flavor. 



Bee Enemy — F. Brewer, WaynesvUle , Mo. — The in- 

 sect which you sent and which you caught with a bee, 

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

 which we referred to on page 5'J. That which you 

 now send is the Spotted Rove-beetle {StapMUnus viacu- 

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

 would be more likely to devour a dead than a living 

 bee. 



Orang:e Raspberry Rust — Isidor Bush, Bushherg, 

 j/-^ —The bright orange rust which is entirely covering 

 the underside of the leaves of many of your raspberry 

 bushes, is the Orange Kaspberry Rust (Vredo ruborum). 

 Knowing that you have the back numbers of our maga- 

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

 on page 238 of our first volume. There is no other 

 available remedy than the complete desti'Uctlon, 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 fungus, which seems to be on the 

 Increase. This answer will sufflce for all.
