busy in one tree climbing out to the tips of twigs, 

 as though after nuts ; and, as the second leaf 

 dropped, I easil}' caught it before it came to the 

 ground. In most instances ever}' inhabitant of 

 the gall had been removed, though now and then 

 one or two were left. The squirrels worked 

 rapidl}', and have cut several thousand leaves 

 from one tree

PorLAR-STEM GALL-LOUSE: a, gall just forming, beneath ; 

 />, do. above ; c, perfect gall, beneath ; </,<?, young double galls 

 — nat. size ; y", stem-mother ; ^, winged female — enlarged (af- 

 ter Riley). 



This is in the yard of Mr. Frank Cornell. A 

 second tree of the same species, in the Ithaca 

 Cemetery, has had quite a number of leaves cut, 

 but few compared with the first named. At this 

 last there are some shoots growing up about the 

 trunk, and I find many galls upon these opened, 

 but the leaf not cut enougli to wither or fall off. 

 If this holds for the whole tree — and I do not see 

 why it should not — they must have opened not 

 less than ten thousand galls on these two trees. 

 Is it generally known that the squirrel is mis- 

 chievous even to this extent? If not, it might 

 not be out of place to have a note made of it. 

 My observations to-day settle the matter beyond 

 all question, as I saw them cut several dozen 

 leaves, many of which I caught as they fell, and 

 examined carefully. — Ithaca, N. Y., June 24, 

 1880.

Cotton Worm in Alabama. — I send you slips 

 showing worms, on the 5th inst., in Marengo 

 County, near Macon station, on the plantations 

 of Collins and Pool. Also, worms in Montgom- 

 ery County, reported by Mr. Kiden on the loth 

 inst. Also, worms on the Conighead plantation, 

 in Perry County, on the 14th inst. ; and contin- 

 ued reports of worms in the cotton fields of 

 Montgomery County up to yesterday. Indeed, 

 I hear of sporadic cases of the appearance in 

 Aletia all along the Prairie belt. The worms are 

 nearly one month earlier than last season. We 

 have had two cool nights, unfavorable to cotton 

 and to worms. — Jas. F. Bailey, Marion, Ala., 

 June 17, 1880. 



Cotton Worm in Texas.— The papers in the 

 State report the appearance of the veritable Cot- 

 ton worm in various sections, but mostly, if not 



entirely, above the 30th parallel, which may be 

 accounted for by the heavy and continuous rains 

 on and above that line. There are no reports of 

 any on the coast, and none nearer than Lavaca 

 Count)^ on the Sun Set route. But heavy rains 

 have just fallen along the coast line, and we may 

 soon expect their advent. — W. J. Jones, Virginia 

 Point, Texas, June 25th, 1880. 



Chinch Bug in Iowa and Minnesota.— North 

 east Iowa and southeastern Minnesota have been 

 greatly infested with Chinch Bugs. They came 

 early in April, and were flying in great numbers 

 about twenty days ago. The}' commenced laying 

 eggs, but, as we have had a wet spring and sum- 

 mer so far, the eggs are mostly destroyed, and, 

 we hope, many bugs also. But wet weather 

 brings rust. Our wheat is struck with red rust. 

 We are in a strait betwixt two evils. If it's dry, 

 we have the bugs ; if wet, the rust. — S. L. Cary, 

 Lime Springs, Iowa, July i, 18S0. 



Cotton Worm in Mississippi. — The Cotton 



Army-worm, the Aletia, has made its appearance 

 here. I have not been able to find the moth, but 

 here are the worms. I find them, though in lim- 

 ited numbers, in the field to-day. They are of 

 all sizes, and I found one already "webbed 

 up." They are in the same place they first ap- 

 peared last year. Though the cotton is about 

 two (2) weeks later than it was last year, the 

 worms are exactly twenty (20) days earlier. — T. G. 

 Smith-Vaniz, Canton, Miss., June 22, 1880. 



Orange Mite in Florida. — In the afternoon I 

 visited a young grove (Mr. Cash's grove) infested by 

 the Rust-mite. The leaves present the same dusty 

 appearance and yellow color as Mr. Norton's. 

 The mites are more numerous than at present on 

 Mr. N.'s trees, but their number has evidently 

 diminished somewhat. They infest both leaves 

 and stem, but arc more numerous on the upper 

 surfaces of the leaves, and particularly congre- 

 gate near the edge shaded from direct sunlight. 

 Some of the older leaves on an infested tree show 

 a brownish coating of rust on their under sur- 

 faces, of the same sort as that which appears 

 upon the fruit. That they spread rapidly over 

 all parts of the tree is evident from their presence 

 upon young and growing leaves, which have 

 pushed out since the late rains began. To-day 

 being cloudy, with some rain, the mites seem par- 

 ticularly active. I observed a small orange- 

 colored Dipterous (?) larva upon an infested leaf, 

 and among the mites. — H. G. Hubbard, Crescent 

 City, Fla., June. 



Larva of Apatura alicia. — You will be glad 

 to know that I have at last got the larva of Apat- 

 ura alicia from Florida. It is now mature, and 

 quite distinct from A. ccltis — one solid green, 

 uniform, no spots or bands. — W. H. Edwards, 

 Coalburgh, W. Va., June 28, 1880.
