Professor C. Stewart, President of the Linnean Society, 

 exhibited and made remarks on specimens of Cijstoccdia inivia- 

 culata, an Orthopterons insect from Namaqualaud, in which 

 the female is far more conspicuously coloured than the mnle, 

 and the stridulating apparatus of the male differs in certain 

 important details from that of other species. A long and 

 interesting discussion ensued, in which Dr. Sharp, Mr. Poul- 

 ton, Mr. Distant, jMr. H. J. Elwes, Colonel Swinhoe, and 

 Mr. Hampson took part. 



Mr. Elwes exhibited specimens of Rihes aurenii) which were 

 covered with galls, as to the nature of which the Scientific 

 Committee of the Horticultural Society desired to have the 

 opinion of the Entomological Society. Mr. Fenn, Mr. Tutt, 

 and Mr. Barrett made some remarks on these galls. Mr. 

 Elwes also exhibited a large number of species of Heterocera 

 recently collected by Mr. Doherty in South-east Borneo and 

 Sambawa. Colonel Swinhoe, Mr. Hampson, and Mr. Dis- 

 tant took part in the discussion which ensued. 



Mr. Barrett exhibited a series of specimens of Noctua /estiva, 

 bred by Mr. G. B. Hart, of Dublin, which represented most 

 of the known forms of the species, including the Shetland 

 type of the form formerly described as a distinct species under 

 the name of Xoct2t<i cunjlua. Mr. Fenn and Mr. Tutt made 

 some remarks on the specimens. 



Mr. W. C. Boyd exhibited a specimen of Diantlmcia Bar- 

 rettii, taken at Ilfraconibe last summer. It was remarked 

 that Mr. W. F. H. Blandford had recorded the capture of 

 D. Barrettii — which had until recently been supposed to be 

 confined to Ireland — from Pembrokeshire, and that its 

 capture had also since been recorded from Cornwall. 



Mr. Tutt exhibited specimens of Polia xanthomista from 

 Mr. Gregson's collection, which had recently been sent to him 

 by Mr. Sydney Webb. They included amongst others a 

 specimen much suffused with yellow, and resembling Hiibner's 

 type and Gregson's type of var. staticcfi, which Mr. Tutt 

 stated was practically identical with Treitschke's nvirocincta . 

 He remarked that certain localities appeared to produce 

 different forms of this species responding largely to their
