right, in that my specimens are intermediate between 0. aranifera, 

 and (). arachnites, but to me it is obvious that all are one, i.e., 

 O. aranifera. The species is locally very variable, as at Folkestone 

 and Hythe. Some localities only yield a single form, and others 

 another single form, but it is not extraordinary to find a variety 

 of forms growing together." 



Mr. R. Adkin exhibited some tobacco leaves that were much 

 infested by a species of beetle. The tobacco was grown in Turkey, 

 and had recently arrived in England. It was found to have been 

 considerably damaged by the ravages of the beetle larvae, which 

 had apparently fed inwards from the outsides of the bale in 

 which the leaf was solidly packed, their burrows often extending 

 from two to three inches into the tobacco. The species was 

 identified as Anobiuii} paniceuiu. 



Mr. West (Greenwich) exhibited a short series of the homopteron, 

 I'sijlla albijie.^, a species recently new to Britain, discovered by him 

 on the white-beam tree, together with the allied P. spartii. which 

 was to be found on broom. 



Mr. Coxhead exhibited leaves of the blackthorn galled by the 

 dipteron, Cccidowyia prinii, from Shooter's Hill, Kent. 



Mr. Graham exhibited a nice aberrational form of Abraxas gros- 

 sulariata in which the black markings of the forewings were coalesced 

 and extended into a wide transverse band with consequent sup- 

 pression of all the usual yellow markings. 



Mr. Sich exhibited the egg-shells of the white ova of Dicranura 

 rimila, which he had previously exhibited, and from which normal 

 imagines had been bred. 



Mr. Blenkarn exhibited a number of the coleopteron Bruchus pisiy 

 found by Mr. Main in peas in a shop at Woodford, Essex ; also a 

 pair of the rare Pterostichas paranrpnnctatns, taken at Chopwell, 

 Northumberland, in May, 1912. 



IMr. Buckstone reported that be had taken Colias edusa at Ascot on 

 June 2nd. It was a freshly-emerged specimen. He had also seen 

 I'ljrameis atalanta and P. carrhii, and at Horsley, on June 3rd, he 

 had seen three more (7. ediisa. Mr. Edwards said that Chrysoclysta 

 linneella was out quite to its average date of appearance this year.

Although the day was fine, and the route taken was through a
