THE AMERICAN 



planted in this part of Missouri. It was the fate 

 of my iirst planting', and as long as people con- 

 sider $2.00 too much for your paper, and ento- 

 mology beneath their notice, they will have to 

 learn the truth from woftil experience. I can 

 now, thanks to the teachings of the Entomolo- 

 gist, show trees as fine, smooth, and vigorous, 

 probably, as those of Mr. Wielandy ; though I 

 cannot say that I am free from the borer. 



[The young borers which escaped your vigil- 

 ance last summer wintered in a dormant state, 

 which accounts for your finding them of the same 

 size either in early spring or late fall. — Ed.] 



Flock of Butterflies — Waxahachie, Ellis 

 county, Texas, 3Iarch 31, 1870. — During my 

 ramble this morning I happened upon a flock or 

 bevy of butterflies, known as Danais archippus, 

 Fabr., containing thirty individuals, four of 

 which I captured for the purpose of identifica- 

 tion, only two of which, however, I pinned down. 

 I find them to be of the genuine archippus, iden- 

 tical in every res])e(t. widi siHM'iniciis bred from 

 the caterpillar by iii\ xir Inst >uiiiiiicr, except in 

 that of color, wliicli i> M>iiit\vliiit paler in these 

 captured this morning tlian it was in those bred 

 by me in the summer. They have the appear- 

 ance of having been on the wing some days. 

 The interes<jing question is, do tlicy hilxTiuite in 

 the imago state, or in that of tlic dir^ -mHs':' They 

 ai-e wholly in advance of their l:u\ al li"Ml-]ihiiit,

[They undoubtedly hibernate in the perfect 

 state, for we have often captured pale, faded 

 and worn specimens quite early in the spring 

 of the year. — Eu.] 



An anomalous Grape Sphinx Moth — Cov- 

 ington, Ky., April 19, 1870.— A friend yes- 

 terday gave me a badly battered specimen of 

 a Philampelus, which is such a curiosity that I 

 write to inquire about it. In size, and in the 

 size and shape of the markings, it is identical 

 with P. satellitia, as figured on page 90 of the 

 present volume of the Entomologist, except 

 that under the double discal dots of the anterior 

 wings is a veiy short and narrow longitudinal 

 dash. (Your figure has three small dots, but 

 all of my specimens of satellitia have only two, 

 although agreeing in all other particulars with 

 your figure.) But the peculiarity about this 

 specimen is, that a longitutliual line down the 

 center divides the insect so that all of the spots 



and patches on the right side of the thorax and 

 abdomen and front wing are light green, except 

 the one on the thorax at the base of the wing 

 and the large one on the hind margin of the wing 

 near the base, which are of a rich dark green, 

 not at all the color of P. satellitia, which I call 

 rather dusky than green. The spots on the left 

 side of the body and left wing are rust-red, vary- 

 ing to a light yellow drab; that on the thorax at 

 the base of the wing, and that on the posterior 

 margin near the base, being dai-ker than the 

 others. The line down the middle would divide 

 the band across the metathorax and first abdom- 

 inal segment into the same two colors. The 

 spots on the two sides of the abdomen also differ, 

 but not so glaringly. The hind wings are alike 

 except that the drab appears again at the jjoste- 

 rior angle of the Ict'l wing: otherwise the hind 

 wings do not difter from those of P. satellitia. 

 The ground color of the left anterior wing is also 

 much lighter than that of the right wing. Both 

 antennae are missing. 



It is clearly not P. achemon or satellitia, as 

 figured by you ; nor P. Linnei, nor Lycaon, as 

 figured by Grote (Pr. Phil En. So., Vol. V., pi. 3). 

 Indeed, the only one of these for which it could 

 be mistaken, would be a hermaphrodite satellitia, 

 in which there had been a wide departure from 

 the normal colors even on the right side. But 

 then I liave never heard that there is any differ- 

 ence as to color between the (^ and ? satellitia. 

 A hole made by some insect in the side of the 

 abdomen shows that it is a female, for the abdo- 

 men is full of eggs. It was picked up dead by 

 some children last summer. What can you make 

 of it? V. T. Chambers. 



Fooi>-Plant of Green SpRAN(iLiNG Slug- 

 worm— j;«««6ei;A, Intl., March 19, 1870.— The 

 green, oval, flattened object, with lateral, tooth- 

 like appendages, fringed with hairs, the two at 

 the tail being longer than the others, and which 

 you say is an undescribed species of Limacodes, 

 or Slug-worm, sent j^ou by me sevei'al weeks 

 ago, were found feeding upon tlie leaves of a tree 

 growing along the Ohio river and creek bottoms 

 in this country, known as the Sycamore tree. I 

 have ascertained this since the specimens were 

 sent to you. Some of the specimens were much 

 larger tlian the one sent.
