several points by which it may be readily distinguished from 

 V. odorata, to which it bears some general resemblance. 

 The leaves are narrower, more triangular, hairy beneath on 

 leaf stalks, and with the edges more or less incurved, the 

 spur longer and ending in a sHght hook ; the lower position 

 of the bracts on the flower-stalk, and the shortness or entire 

 absence of runners. White flowers are almost as plentiful at 

 Mickleham as those of the normal purple tint, whilst an 

 intermediate form has much paler flowers with a white centre. 



Mr. Manger exhibited a very perfect specimen of the 

 elephant beetle, Megasouia elephas, from Venezuela. The 

 delicate pile with which the thorax, head, and elytra are 

 covered at first was practically intact. 



Mr. Edwards exhibited specimens of Papilio neptunus from 

 the Malay, P. karna from Java, P. andrcEinon from S. America, 

 and Morplio anaxihia ^ and ? from Brazil. 



Mr. Hy. J. Turner exhibited living larvae and cases of: 



(i) Colcophora lixdla, with its case made of pieces of the 

 various grasses upon which it feeds. He noted that in its 

 pre-hybernating stage the larva feeds exclusively on Thymus 

 serpyllwn, from the calices of the flowers of which it forms a 

 rough case. These cases may occasionally be found aban- 

 doned in the spring and affixed to the stems of grasses. It 

 was a somewhat rare species. 



(2) Colcophora conyzcs, with its case made of portions of the 

 cuticle of the leaves of Imda conyzce or /. dyscnterica. In its 

 young stage it has a straight case, very dark and apparently 

 made of silk, in which it hybernates and feeds for a time in 

 spring. This it later on abandons and mines into a leaf, 

 leaving its young case behind. It soon builds a new case from 

 the cuticle of the leaf, which is very hairy. When this is too 

 small it abandons it and forms another, leaving the old one 

 affixed to the mine. Thus it differs from many cuticle- 

 builders, which enlarge their cases rather than build new 

 ones. This species, he stated, was an exceedingly local one. 



(3) Colcophora troglodytclla, with its smooth case made of 

 silk. This species was feeding on /. dyscnterica, and was 

 fairly common in some districts of Great Britain ; it often 

 occurred on Enpatorium cannahinum. 



He stated that he was indebted to the kindness of Mr. 

 Eustace Bankes, of Corfe Castle, Dorset, who had sent him 

 numbers of larvae of all three species. They were all found 

 in the Isle of Purbeck. 



Mr. Sich exhibited a short series of Cramhus chrysonuchcllus 

 from the chalk hills east of Guildford, and ^ and apterous $ s
