V. thompsoni x v. thompsoni, 



which should produce wholly v. thompsoni. 



Mr. Newman exhibited several portions of the stems of 

 Viburnum, and pointed out the evidence of the presence 

 of larvae of Sesia andreniformis, viz. the " caps " covering 

 the openings from which the imagines would subsequently 

 emerge. He had met with a considerable number of attacked 

 stems in a shaded area among trees. It was noted that the 

 larvae were found in both V. lantana and V. opulits, and 

 usually in more exposed situations; but Mr. Rayvvard said 

 that he had met with evidences of the presence of the larvee 

 in at least two shady localities. 



Mr. Tutt remarked that the ova of the species of ^geria 

 (Sesia) were laid anywhere on their respective food plants, 

 even away from the woody parts, on the leaves. They were 

 dark brown in colour. It was very remarkable that, so far 

 as was known, the young larvae in their first skin were hairy, 

 and bore no resemblance to the shiny boring larvae of the 

 later instars. This suggested that during the first instar the 

 larvae were external feeders. But really what was known of 

 them was only sufficient to express ignorance. Reliable 

 information of the earlier stages was urgently needed. 



A considerable discussion ensued. 



FEBRUARY 25M, 1909. 



Mr. F. J. Stone, of Clapham, was elected a member. 



Dr. Hodgson exhibited a series of Nemoria viridata, 

 obtained in 1906-7-8 from Lancashire and Surrey. The 

 specimens included Linne's typical form, that usually met 

 with, specimens of a grey green, of a blue green, and of a 

 yellow green ; some with lines very distinct, others with 

 them very indistinct, the form ab. concavilinea, and various 

 examples, of which some were irregularly and some 

 symmetrically bleached. He showed pupae of the same 

 species, spun up in glass tubes among heather, having much 

 silk in evidence. In addition he exhibited a female of 

 Celastrina argiolus, a third brood specimen, in which almost 

 all the blue was replaced by dull grey or leaden blue, together 

 with a pupa of the same species in a glass tube, having a 

 considerable amount of silk threads around it. 



Mr. W. West (of Greenwich) exhibited one of the Society's 

 cabinet drawers of Coleoptera, being the first portion of the 

 collection as rearranged.
