JUNE i^tk, 1900. 

 Mr. W. J. Lucas, B.A., F.E.S., President, in the Chair. 



Mr. West exhibited the following three species of Hemop- 

 tera : 



Harpocera tJwvacica, obtained by beating oak ; Berytus 

 minor, sweeping grasses ; Salda cincta, at the sides of ponds 

 under refuse. All three species were taken in Hither Green 

 Lane, Lee. 



Mr. H. J. Turner exhibited a twig of red currant from his 

 garden at Hatcham, infested with a large scale, Pulvinaria 

 ribesicB, Signoret, and contributed the following note : 



"The female specimens of scale exhibited were found on 

 a red currant bush much overshadowed by vigorous growth 

 of Clematis vitalba. I consulted that useful series of notes to 

 all interested in economic entomology, viz. ' Reports and 

 Observations on Injurious Insects,' by Miss Ormerod, and 

 found in the number for 1889 that the pest was in all prob- 

 ability Pulvinaria rihesice, a somewhat rare occurrence in this 

 country. I then submitted specimens to Mr. R. Newstead, 

 F.E.S., of Chester Museum, whose work in this group is 

 well known, and he writes me as follows : 



" ' Yes, Pulvinaria ribesia:, Signoret. Thank you very much 

 for the specimens. I am delighted to have them, and shall 

 find them very useful. Did you observe the small and now 



untenanted S scales ? They are glossy white 



I have never seen a male, and as these have not been 

 described, perhaps you would look out for them next 

 season ? ' 



" According to the account given in ' Injurious Insects,' 

 i88g, pp. 43—48, the scale is known as the white woolly 

 currant scale ; it is a native of France, and is allied closely 

 to the well-known and destructive vine-scale, Pulvinaria
