Apple-tree Worms — C/iaiiix Watcm, Spriiuj- 

 rlll,-. W7.w»«x/«. — Tlie snmll wliiti^ moth.x, whiel'i. 

 as yoii «ay, ' ■ eauie by luillions the last of iMay 

 and laid th(ur eggs on tlu^ tips of the new slioot-s of tlie 

 aiiplc trees, ft'om vvhieh eggs there hatehed out maggots 

 with a l)Uiek head, so that in a few woelts the tops of 

 the appli^ trees were alive with worms." are too much 

 torn and rubbeil to identify the species with any cer- 

 tainty. No such mofhs are at present l<nown to infest 

 apple trees in the manner you describe. So far as we 

 can judge from the very poor specimens sent, we think 

 yoiu- moths are the Cimjcia ccntitWata of Guenee, the 

 hal)its of which insect are, we believe, unknown to 

 scienee. The ••maggots with a black head" cannot be 

 i(k-ntitied from your brief notice of tliem. 



It could scarcely have l>ee.n the canker-worm that 

 stripped the api)le trees last year of their leaves in July, 

 for that insect appears the end of May and in June. 

 'I'he Canker-worm is a measuring-worm. You give no 

 description whatever of those- which you speak oi'. 



Uuk't'lgr tiall — .1. F,:Hdler, Allentoii, J/o.— The 

 dense cluster of yellowish galls, spongy and bladder- 

 like, and all closely pressed to each other, which you 

 found on the twigs of tlie White Oak, are caused by the 

 Stout-horned Cialltly ((>/«;>.< /o)'//i7-/7t/«,'Vyal.sh)-^a small 

 ant-likc wingless species which exists only in the female 

 sex, like many other gall-flies. Dr. Fitch supposed 

 this gall to be produced by what lie called the Oak-tig 

 Gall-fly (Cymps ,[. ficus, Fitcli,) " a small black tly 

 with the lower half of its head, its antenme and legs 

 pale dull yellow, its hind shanks dusky and its abdo- 

 men beneath reddish-brown." But it was long ago 

 proved by the Senior Editor that Fitch's supposed gall- 

 maker is a mere Guest-fly, inhabiting a gall which is in 

 reality made by tlie Stout-horned Gall-fly. (See Osten 

 Sackeu's I'apcr on (iiill-flies, Proc. Ent. Sue, Phil., 

 IV. pp. 353,368-9). 



Insects nainefl — Ih: /'. L. P/iunx, WoodHllr, 

 .Uixs. — 1st. The Hawk-moth is VUttrocampa ^frsii. a not 

 \eiy common species. 2d. The Ci'aida captured May 

 10, 1S69, in a grove where the Periodical brood comes 

 out 1858, 1871, etc.. is a genuine C. tredecim. Its occur- 

 ring two years before the regular time is very remark- 

 able and unusual. Still, many analogous irregularitii's 

 are recorded of several other insects; and supposing all 

 the difl'erent broods of this insect to have sprung from 

 a common origin, we must bear in mind that it is only 

 through such irregularities as these, in the first instance, 

 that distinct broods with distinct periodic times could 

 ever have been permanently established, .".d. 'I'be 

 larva • •found in branches of peai', hickory, etc. , cul olf 

 by the parent insect," is most probably, judging from 

 your drawing, that of the Twig-girdler U'«(vV/.n« .•/»- 

 ijulatus) which we figured and ileseribcd in a lormer 

 number. 



Small Apple-leal' « onus — llennan. I'oiiiiilnii , 

 IIV/As Ci'ni,n, 7'u.— The pale-bniwn worms about half 

 an inch long, with shining black hca<l and neck arc. we 

 believe, the Iar\'a' of the Eye-spottid Hud-moth (Spl- 

 lonota Ofiilaiia, Harris). If so, they will change into 

 the pupa st.itc within the folded leaves, and will come 

 out in July in the form of a small dark gray moth. 

 The only a^•ailable mode of fighting them is to .gather 

 the infested leaves which they have tied together with 

 silken cables, and destroy th(!m. We notii-e that some 

 specimens hav(^ already spun their cocoons among the 

 leaves. So far as we arc aware, this worm does not 

 occur in the West. 



Rose-bug' on Apples — A. Veaii, (Hti\ liidi,iii,i. — 

 The yellowish beetles, about % inch long, which '• gen- 

 erally infest the Persimmon tree , but have left it and 

 are eating the young apple trees that are near by, not 

 a single one having escaped," are the common Rose- 

 bug {Maorodadylas suhspinosus, Fabr.) You will not 

 prevent their injuries by cutting down your Persimmon 

 trees, because this beetle jireys voraciously both on the 

 Rose, the Grape, the Plum, anil the Cherry as well as 

 on the Apple and Persimmon. As it lives underground 

 in the larva state, feeding upon the roots of plants, its 

 injuries cannot easily be warded off. The only way is 

 to shake down the beetles and destroy them. 



TJuicorn Apple-tree Caterpillar — G. (.'. Krml- 

 /((;(f./.--The reddish-brown caterpillar with the second 

 and third segments green , and a prominent horn just 

 l)eliincltheiii, which has the habit of holding up the tail, 

 is known to feed on the Apple, Dog- wood. Plum, Al- 

 d(U-and Winterberry. . It is the larvaof a moth with the 

 fore wings light brown , variegated with greeni.sh-whUe 

 and darli -brown, and the iiind wings cj whiti.sli with a 

 dusky spot on the inner hind angle , and those of $ 

 duslcy. This moth is the Notoioida iinicomie of Sm. 

 and Abb, and may be called in English the Unicorn 

 Notodonta. 



Liargre Water Beetle — S. E. Muiifvrd, Friiicetoii , 



Ind.—'nie large flattened shiny blackish beetle, with a 

 dull orange border, and the wing-covers thickly covered 

 with numerous minute longitudinal impressed lines, is 

 a large species of water beetle, { Cyh inter Jimlriolat us, 

 Say,) and yourfijiding itflying around a barrel of rain- 

 water is in accordance with its habits. Thanks for your 

 flattering encomium.
