Mr. F. Noad Clark exhibited an example of the sweet flag, 

 Acorns calamus, and stated it was the only close relation 

 we had in the British flora to Arum. He pointed out that 

 what was often taken to be a leaf was really the spathe of the 

 flower-head, as in the " hood " of the arum ; the true leaves 

 could always be recognised by their corrugations. Mr. Clark 

 also showed the fruit of the henbane (Hyoscyantus niger). 



Dr. Chapman exhibited larvae of Arctia villica, from ova 

 laid by a female captured in Sicily in April last. He also 

 showed the ova laid by bred imagines of Graellsia isabclhx

 way. 



Mr. Stonell exhibited an example of Abraxas sylvata 

 (uliuata), taken in the Clapham Road. 



Mr. Sich exhibited the ova of Coleophora gryphipcnnclla, 

 in situ on a rose-leaf. It was undoubtedly an " upright " 

 egg, and was so abundantly gummed on as to appear partly 

 buried in the leaf. Apparently it belonged to the higher 

 group with C. laricella, but was much taller. 



Mr. Colthrup exhibited an album containing a number of 

 photographs of clutches of bird's eggs in their surroundings. 

 Those of sea-bird's eggs were remarkably well done. 



Mr. Main showed larvae of Papilio machaon at different 

 ages, obtained from ova sent him by Mr. Browne. He also
