Mr. Bedwell exhibited his series of British beetles of the genus 

 Benibidiiim. 



Mr. F. W. Edwards exhibited photographs of a curious new form 

 of the Diptera in which the wings showed an increase in the num- 

 ber of veins normal to the group. (See " Proc. Ent. Soc. Lond.,"

Mr. H. Worsley-Wood, of Acton, was elected a member. 



Mr. Robert Adl<in exhibited a short series of Diaphora mendiva 

 from Co. Cork, and of a form from Co. Tyrone, Ireland. He said 

 that the form with the white, slightly spotted male, represented by 

 the Co. Cork series, was known as var. mstica ; but it would be seen 

 that in the specimens from Co. Tyrone not only were the males of a 

 whitish grey colour and somewhat more spotted than in the Cork 

 form, but that the veins of the wings were indicated by black-grey 

 streaks, and in the females this character is even mote pronounced. 

 Thus we have an insect, which in both sexes has all the wings pale 

 grey, normally spotted with black and the veins dark grey. It 

 appears to be a well-defined local race, for which he proposed the 

 name var. venosa. 



Mr. L. N. Staniland exhibited large specimens of the galls 

 formed on the roots and branches of wild crab-apple trees in North 

 London by the woolly aphis, SchizoneHra lanitjera. The largest
