between markings and ground is very much stronger than 

 in an}' of the other forms. In the worn specimen of this 

 form there is little loss in these melanic characters. Tliere 

 is no trace of the ' ochreous tinge' of the type, nor of the 

 'pale grey ground-colour.' This, compared with the normal 

 form, is a very striking one, and might be well termed var. 

 fusca." 



Mr. L. W. Newman exhibited two specimens of Pvlygonia 

 c-albmn, bred on October 19th and 20th, igio, by the Rev. A. 

 Stiff, of Leigh-on-Sea. The specimens are var. Imtchinsoni, 

 which form has not previousl}'^ been obtained as an autumn 

 emergence. Two others were bred about the same time, also 

 some twenty very varied examples. With these two were 

 shown a varied series for comparison, of summer, autumn, and 

 summer var. hutchinsoni, forms. The whole of the summer 

 brood specimens were bred from ova laid by a female captured 

 in the Wye Valley, and the autumn examples were the result of 

 in-breeding from the former. These autumn var. hutchinsoni 

 were from the same female as the yellow forms exhibited on 

 a previous occasion. 



Mr. Step exhibited a living group of the discomycetous 

 fungus Humaria rutilnns, from Ashtead ; also a sporophore 

 of Menilins lachrymans (" dry rot "), from a house in the same 

 neighbourhood where the species had effected wholesale 

 destruction of the woodwork, involving very expensive 

 reconstruction.
