had been gathered and put into a glass with water, which 

 probably diluted the nourishing qualities of the leaf, so that 

 the larva had to mine a greater distance to obtain its full 

 amount of sustenance. 



This species mines indifferently either in Rumex acetosa or 

 R. acetosella. I have found numerous mines in the leaves of 

 both these species of Rumex. 



Mr. H. S. Fremlin read a short paper entitled " Insects as 

 Carriers of Disease " (see p. 14). 



SEPTEMBER 10th, 1908. 



Messrs. Harrison and Main exhibited a series of Macaria 

 liturata, bred from ova laid by a female taken in Delamere 

 Forest in 1907. Of the fourteen insects bred thirteen were 

 of the dark form var. nigrofulvata, and one of the typical 

 form. In one example the fulvous submarginal band was 

 nearly obsolete. Mr. Harrison remarked that from 25 per 

 cent, to 30 per cent, of the specimens captured were of the 

 dark form. 



Mr. L. W. Newman exhibited Abraxas grossulariata, a 

 long and varied series, including ab. varleyata, ab. nigro- 

 sparsata, a rayed example particularly well marked on the 

 hind wings, and dark examples from Aberdeen ; Selcnia 

 tetralunaria (illustraria), a fine aberration in which the whole 

 surface was very darkly powdered ; Noctua rubi, a large 

 yellow aberration from York ; Gnophos obscuraria, a pair of 

 the extremely light form of ab. mundata, from Lewes ; Pieris 

 napi, a rayed form ; Notodonta dictcea, an extremely dark 

 form bred from Bexley ova ; A rgynnis aglaia, a very long 

 series, mostly bred from ova, and including a good range of 

 variation from very light to melanic forms ; also one with a 

 rich brown underside ; they were from North Kent. 



Mr. Tonge exhibited a large species of Ichneumon (Pro- 

 tichncumon cryihrogaster), bred from a larva of Therctra 

 porcellus, taken at Sheringham. 



Mr. Hy. J. Turner exhibited a very finely marked female 

 underside of Ercbia cethiops taken at Gersau, L. of Lucerne, 

 on July 27th, having the bands very brilliant in colour and 

 contrasted in depth, there being five well-marked eyespots 

 on that side, and six on the upper side. 



Mr. T. W. Hall exhibited an abnormal flower of the 

 sweet pea in which the wing parts were duplicated, and 

 expressed the opinion that such irregularities were some-
