On behalf of Mr. Alderson, Mr. Main exhibited several 

 specimens of a Dipteron bred from larvae passed through the 

 intestines of a child. They had been identified as Musca 

 domcstica. It was stated that although similar records had 

 been made before, the species had not hitherto been iden- 

 tified. The child was stated to have ravenous and dirty 

 habits. 



Mr. Robert Adkin exhibited a short series of Anchocelis 

 rufina from Rannoch, together with series of the same 

 species from the English Lake District, Yorkshire, and the 

 South of England, for comparison. The first mentioned 

 specimens were taken near the shore of Loch Rannoch, and 

 were the most richly coloured and brightest of the four 

 series, in this respect more nearly resembling those from the 

 South of England than either of the others ; both the Lake 

 District and Yorkshire series were of a paler and duller 

 form. 



Mr. Montgomery and others reported that Pieris napi had 

 been seen during the last two or three weeks. 



Mr. Newman said that at the present time P. napi, P. 

 rupee, and Vanessa atalanta were more or less common in 

 Devonshire. 



APRIL nth, 1907. 



Mr. Lucas exhibited a living specimen of the rare Ento- 

 mostracon, Chiroccphalus diaplianus, found in water in cart- 

 ruts in the neighbourhood of Claygate. 



Mr. R. South exhibited preserved larval skins of Gastro- 

 pacha qucrcifolia , showing four stages of growth ; and a full 

 grown larva, also inflated, of Epicnaptera ilicifolia. He called 

 attention to the orange markings on the second and third 

 thoracic segments of the ilicifolia and of one of the qucrcifolia. 

 In the former the orange marks were divided by a blackish 

 dorsal line, and had a black spot on each side, whilst in the 

 latter, which was probably in the third instar, each orange 

 mark had a large central black spot and a black dot on each 

 side. 



He further showed the cocoon of E. ilicifolia, which was 

 spun up in the terminal leaves of a twig of bilberry, and 

 looked not unlike a spider's web, often to be seen in a similar 

 position ; the inflated skin of a half-grown larva of Lcelia 

 ccenosa, and the cocoon of the same species. Also a pre- 

 served larval skin and the cocoon of Drcpana harpagula 

 (siatla).
