Cocoons and Cbrysalids na.meA—A. S. Fuller, 

 EiJgewood, N. ^.— The large black chrysalis, measur- 

 ing nearly two inches in length, and one inch in 

 difinictcr," belongs to that large and beautiful moth 

 known as tlie Regal Walnut Moth (Ceralommpa regalig, 

 Ilarr.) The front wings of thi* moth are ]ialo olive, 

 adorned with yellow spots and vcinrd witli n.ldisli, 

 while the hind wings are or:ingi' i-'d. Il^ rali i |ull;ir 

 feeds on Black Walnut,Butternut, llirkMij . l'riHi]iiii..n, 

 and Sumach, and is, wlien full grown, :ni immense 

 j,'i-eeii ii-.:iiiii'e, with 10 long orange horn-like and 

 liri kly -piiH- neai- llii' liead, and other shorter black 

 our- nil ih( II -I oi ilie linily. The Smaller, mahogany- 

 eoldi', il ilirvsalid^ talvcn IVom the earth belong, doubt- 

 less, to some species of Owlet :Motli {Xodna family), 

 lint it is impossible to identity the >iie, ie- until the per- 

 fect insect escapes. The f;ray. silkm (■.inions, woven 

 within a leaf and attached to the t\\ i^ by a lung silken 

 cord, belong to the Promethca Moth (AUucus Protne- 

 thea, Drury). The larger looser cocoons of the same 

 color, attached lengthwise to difl'erent kinds of twigs, 

 and among others to that of a blackberry , are those of 

 the Cecropia Moth (.J«a(!«« Cecropia, Linn) The co- 

 coons which are more tightly woven, rounder, lighter 

 colored, and usually spun within leaves, are those of 

 the Polyphemus Moth (Att.icus r.^hijihanus, Linn.) 

 Finally the eases which hang pemlant trom a inimber of 

 different .shrubs and trees, both deciduous and ever- 

 green, aiul which are generally covered with pieces of 

 leaves or stems, belong to the Bag- worm (Thyridopteryx 

 tphemera/onnis , Haw.) 



TTbite-Iined IHorningr Sphinx — Stephen Blan- 

 chard, Oregon, Holt Co., Mo —The beautiful hawk 

 moth which you send, distinguished principally by Its 

 roseate under-wings and by a broad pale band running 

 from the apex lo the base of the <l:irk olive upper- 

 wings, is the White-lineil Moniin- Sjihinx (DeUepIdla 

 lineuta, Falir.) II is a l.ileial.ly i-ommnii insect, and 

 may quite IVeqiiently be sem, at twiliiflit and even 

 during the day , hovering, hiimmin^-liinl-rashion. over 

 Verbenas and other Howers. Its laiva feeds upon 

 pur.slane, turnip, buckwheat, wati rmelnus and even 

 apple leaves, upon any of wliirh it may lie Imind in 

 the month of July. It descends into the ground, and 

 within a smooth cavity, changes to a light brown chry- 

 salis, from which the moth emerges during the month 

 of September. The most common color of this larva 



spots, each spot consisting of two curved bin 

 enclosing superiorly a bright crimson spot and interiorly 

 a pale yellow line— the whole row of spots connected 

 by a pale yellow line, edged above with black. Such 

 is the accepted larva of this moth, and it is not gener- 

 ally known that a black vaiieiv iM.iii<, di tiering totally 

 in Its markings from ilie meiii \ariity Thi's insect 

 has a wide range , as it i.rriir- in \\ r^t linlia. Mexico, 

 and Canada, as well as in all part- ol the I iiited States.

 erechthea, Guence, a very eommon owlet moth. We 

 have observed that the sjirin- Inood of this insect are 

 always several sizes smaller tlian the autumuaf brood, 

 and at one time wc snpposed the two forms to belong 

 to distinct species. The three small larvae ' ' found 

 feeding upon the younger leaves and unopened Howers 

 of the woodbine,'' belong to some owlet moth, and 

 apparently to some of the climbing cut- worm moths ; 

 but we cannot identify the species with auv certainty. 

 The two-winged Hv, banded with blaek amfvellow like 

 a wasp, whigh you iiotieed ilvini,' round v.'iur honey-

 genus Scmm, and should therefore he eareliillv inntei-ted 

 instead of being destroyed. Its larva is a legless mag- 

 got, and feeds most ravenously upou Plant-liee. 



Feacb Twig Borer — Wm. Muir, Fox Creek, Mo.— 

 The livid brown worm, with whitish longitudinal 

 stripes, which Is boring into and ruining great num- 



t*'S' ""■' "buds" and shoots, 



is evidently the com-

 {Goiiyna nttela, Gue-

 rin" to that page, it Inhabits the stems of a number of 

 different plants, though the fact of its also boring into 

 peach stems is an entirely new one. At Figure 140 this 

 borer is represented as 'it appears when full grown. 

 Those you send are but one-third grown, and as the 

 point oi' entrance is always discernable by a slight dis- 

 colored spot on the stem ."you might save many of your 

 "buds" which show this sign, by carefully cutting out 

 the borer. In this way we have often saved plants of 

 the Dahlia, to which this borer is very partial. 



The Apple-t\wig' Borer— ^. BincTclen, DuBoia, 



Ill.-The beetle that you tiud boring in the stems of. 



your young apple-trees is the Apple-twig Borer {Boa- 



trichus lieaudatus. Say, Fig. 141). Unlike the two com-

 which we should also inter from the fact of both sexes 

 occurring therein in about equal numbers. With in- 

 sects, as a general rule, it is only the female tluat labors 

 for the well-being of her future family. 



Apple-tree Borers on South Side of Xrees — 

 Jno. F. Wh'laiuhi, Jefferson City, Mo.— It has long been 

 known that the Flat-headed Apple-tree Borer (C/iryso- 

 hothris femoriifn , Fabr.) prefers what are known as 

 "sun-seaMed"' iri'e^. nnd that it is almost invariably

 Ills., who states, ( IlVWfrw, Ji'ural, Apr 29, '09) that '• he 

 has never known it to occur in a healthy tree, but al- 

 ways in those partially killed by sun-scald." Your 

 exi^erieuce confirms the fact. 



Cocoons of the Cecropia Moth — Thos. W. 

 Gordon, Georgetown, Ohio.—'ihe large cocoons taken 

 from various trees are not those of the Polyphemus, 

 but of the Cecropia Moth. The cocoons of the former 

 spi lie- are viry closely woven, tough and hard, bluntly 

 n\al ill tniin lind of a pale butt' color. Those of the 

 latii 1 all nt an ashy-brown color, much more loosely

 end. 



Flea-beetles— Co?. Fred. Uecker, Lebanon, St. Clair 

 Co., 111.— The minute brassy -brown flea-beetle that, as 

 you say. covered your wheat-fields and meadows, but

doubt ])rcys upon living vegetation. 



Grape-vine Caterpillar — E. S. Foster, Bush- 

 hurg. Mo— The caterpillar which is eating out the ter- 

 minal buds of your grape vines is entirely new to us.
