in 1893, and others (now exhibited) came forth this year. In 

 1892 the larvae were throughout sickly, the result, so far, 

 being the two undersized specimens now shown. Last year 

 the brood was healthy from the time of leaving the egg until 

 pupation, yet no imagines have appeared thus far. Indeed, 

 although I have now had several years experience in rearing 

 this species, I have on no occasion found the imago emerge 

 during the year following that in which the larva fed up, at 

 least two and often three years being spent in the pupa state. 

 "The five specimens of Aleucis pictaria, Curt., were bred 

 from larvae taken in the New Forest last summer. Of some 

 thirty larvae that I then had, only about half a dozen were 

 near full growth, the others being in various younger stages, 

 and so far as I have been able to follow them, only those that 

 were on the point of pupating at the time when they were 

 taken have produced imagines, the younger larvae refusing to 

 feed up in confinement, although liberally supplied with their 

 natural food — blackthorn. This entirely agrees with my 

 previous experience with the species, and I am inclined to 

 think that the peculiar habitat of the larva renders some 

 special treatment, which I have not yet succeeded in dis- 

 covering, necessary." 



Mr. Adkin' also exhibited on behalf of Mr. R. Armstrong 

 Adkin, a series of Cyclostoma elegans. Mull., taken on the 

 occasion of the Society's Field Meeting at Reigate on 

 Saturday last. The shells showed considerable variation, 

 some being of a uniform bone colour, while others were of 

 the more usual reddish shades and banded, some were also 

 mounted so as to show the operculum peculiar to this 

 species. 



Mr. Step remarked upon the wide range of variation shown 

 in the specimens of C. elegans, especially as they were 

 obtained in one spot. It was the only British land mollusc 

 which had a true, fully developed, calcareous operculum. It 

 was attached to the tail and presented a very curious appear- 

 ance when the animal was extended feeding. 



Mr. Frohawk exhibited an ovum of Vanessa c-alhim, L.. ift 

 situ, on a nettle leaf, together with larvae of the same species, 

 showing all five stages of growth. They were from the same 

 parent, and were part of a batch of 270 ova, laid at intervals 

 from April 17th to June 1st. The whole of this large 

 number of eggs were fertile. 



Mr. Frohawk exhibited, on behalf of Mr. Fremlin, an 

 interesting variety of Apatura iris, L., from Berlin, inter- 

 mediate between the type and var. iole, Schiff.; and on behalf
