portions of Exmoor ; the connection between which and the 

 locality referred to was only interrupted here and there by an 

 occasional strip of cultivated land. Between these patches of 

 arable land are broad areas of common covered with heather, 

 gorse, and bilberry. Large detached masses of rock lie 

 scattered here and there along the sides and at the bottom 

 of the glen, which are now almost entirely covered by 

 vegetation. At the shore end, however, the rocks, which 

 belong to the Middle Devonian system, and consist of red and 

 grey grit, shales, and sandstones, stand out clear and bold. 

 The series of specimens exhibited included strongly-marked 

 examples of the type-form ; an extreme form of var. conversaria. 

 Hub., a form intermediate between the type and the last- 

 named var. ; examples of var. destrigaria, Steph. ; and another 

 form, believed by Mr. South to be the issue of a cross between 

 the var. conversaria and the var. destrigaria. In support of 

 this suggestion Mr. South said that in 1883 he bred about 

 equal numbers of the type and conversaria forms from ova 

 deposited by a banded female, which he had every reason to 

 suppose had paired with a typical male. It was apparent, on 

 looking at the entire series, that the extreme forms were in 

 each case connected with the type by intermediate forms and 

 their aberrations. 



Mr. E. B. Poulton exhibited young larvas of Apatura iris, 

 which had been beaten off sallow in the New Forest. He 

 also exhibited eight larva? of Sphinx convolvuli, of which seven 

 were in the fourth stage and one in the third. A female moth, 

 captured in S. Devon by Mr. Pode, laid eighteen eggs on 

 August 29th ; all except one of these produced larvas by 

 September 9th, and up to the date of the meeting only a 

 single larva had been lost. Mr. Poulton said the life-history 

 had been of extreme interest, throwing much light upon 

 that of Sphinx ligustri, as well as upon difficult points in the 

 ontogeny of the allied genera, Acherontia and Smerinthus. 



Mr. Stainton commented on the interesting nature of the 

 exhibition, and said he was not aware that the larvae of 

 Sphinx convolvuli had ever before been seen in this country in 

 their early stages. 



Mr. M'Lachlan remarked that females of this species
