Apion hookeri, A. confluens, and CcuthorJiynchus rugulosns ; all 

 taken near Erith on chamomile. 



Mr. Simmons exhibited the larvae of Eupithccia subfulvata, 

 found feeding on Achillea millefolium in his own garden. 



Mr. Main exhibited the ova of a "stick" insect, Bacillus 

 rossi, which much resembles a short-stalked seed. 



Mr. R. Adkin exhibited a series of Melanippc galiata reared 

 from ova obtained at Eastbourne in September, 1906. He 

 said the parent female was quite an ordinary example of the 

 dark-banded form, but the progeny, which emerged between 

 June 7th and August 4th of the present year, varied consider- 

 ably in the tone of colour of the transverse band, from one, 

 the first to emerge, in which it was of a very pale bluish- 

 grey tint, to one of quite the dark-banded form similar to 

 the parent, which happened to be the last to emerge; the 

 remainder of the brood consisted of individuals covering all 

 grades of variation between the two, and they emerged 

 indiscriminately between the first and the last, light and 

 dark forms often coming out on the same day. He men- 

 tioned that on a former occasion he had reared a brood 

 under similar conditions, except that in that case the parent 

 female was of a light. form, but the progeny varied in much 

 the same way as in the present case. In neither instance 

 was the male parent known. He further stated that, in his 

 experience, very few pale forms were found among the wild 

 examples. 



Mr. Henry J. Turner exhibited leaves of birch showing 

 the web, feeding gallery, and cocoons of the Hyponomeutid 

 moth, Swammerdammia griseo-capitella, and contributed the 

 following note : 



" The larva spins an intricate web of very fine threads on 

 the upper surface of a birch leaf, gradually causing the mid- 

 rib region to become depressed and the margins to be more 

 or less raised and approximated. Among this collection of 

 web is formed a cylindrical chamber, open at both ends, 

 general^ parallel to the mid-rib, and raised above the 

 surface of the leaf, which tube the larva usually occupies. 

 It feeds upon the upper cuticle and parenchyma of the leaf, 

 reaching down from its chamber, but generally keeping its 

 hind segments in the tube while doing so. Such is the 

 colour of the larva and its position in the colorless tube, 

 that the combination of light and shade render its recogni- 

 tion very difficult except by careful examination. Add to 

 this the fact of its extreme agility to drop by a thread, when 

 disturbed, and also its habit of lying perfectly straight in the
