eggs on the keys — which are still green — so I imagine the second brood has still to 

 feed up, or else there must be a succession of broods throughout the summer. I 

 have found a few cocoons on other maples on the opposite side of the town, where 

 I took a single imago some 20 years since. If the higher boughs of the tree on 

 which I took these cocoons contained an equal number there must have been several 

 hundreds on this one tree, as I gathered over six score from the branches that were 

 within reach of my stick. 



I believe the cocoon is described by Mr. Stainton as pink and attached to the 

 mined key, but in no single case did I find this to be so. I cannot help thinking 

 that the insect might be easily found in other places where the maples flower freely.

[The original notice of this larva is by Colonel Groureau — Ent. Annual, 1861, p. 

 170 — who found it feeding in the keys of Acer platanoides, and spinning its cocoon 

 upon the mined key. He describes the cocoons as flat, y ell oioish- white, white, or 

 whitish -rosy. In this case the infested keys had fallen to the ground unripe. The 

 moths emerged at the end of June and beginning of July. — Eds.] 



Occurrence of Gelechia scotinella, H.-S., in England. — In April of the year 1873, 

 I collected a quantity of distorted shoots of sloe, from which, among several species 

 of Lepidoptera, I bred, at the end of June and beginning of July of the same year, 

 four specimens of a fuliginous Gelechia unknown to me. I delayed ascertaining if 

 the species were known to others until I should have discovered its larva, which I 

 hoped to do in the following spring ; but when that time arrived circumstances 

 precluded my searching for it, and, by degrees, the matter dropped out of mind. 

 When putting my Tineina in order, early in this year, I came across the moths in 

 question, and then forwarded two of them to Mr. Stainton, who obligingly deter- 

 mined them as the Gelechia scotinella, H.-Sch. Through the kindness of Prof. 

 Zeller, Mr. Stainton was enabled to inform me that the species had been bred by 

 Herr Sauber at Hamburg, from the same plant ; also that the insect has been caught 

 at Prague, Yienna, Jena, and Wiesbaden. 



In Staudinger and Wocke's "Catalog," the species is placed before G. sororculella. 

 Last spring I visited the place which had yielded me the larvae, and collected a large 

 number of similarly distorted shoots of the sloe, but none of the contained larvae 

 pertained to the species required.— J. E. Eletchee, Worcester : September, 1881. 



Leaf-mining larvce extracted by birds (?). — The larvae of the genus Tischeria 

 j are frequently extracted from their mines by some small bird, as I imagine. The 

 j exit-hole is larger than would be made by the larva, and the cuticle around is torn, 

 which would not be done by the laiwa. By the dimensions of the mine, the larva 

 must be nearly full-fed at the time of extraction. The species I have observed 

 most affected in this way are T. angusticollella, dodoncea, and complanella — the 

 first most commonly. — Id. 



[Mines of Lithocolletis may often be found torn open in a similar way. I fancy 

 some of the Tits are the offenders. — H. T. S.]. 



Platyptilia dichrodactyla and Bertrami. — After the appearance of Dr. Jordan's 

 first paper on the Pterophori of Europe and North America compared, in one part 

 of which he made some references to the identity of the two plumes above named, 

 I wrote him a few lines, embodying my experience of one of them, dichrodactyla. 

 Dr. Jordan, in the kindest manner, desired me to communicate them to the Maga- 

 zine, as he thought there were some points of interest bearing on the question of
