116 [April, 1892. 



Professor C. Stewart, President of the Linnean Society, exhibited and made 

 remarks on specimens of Cystoccelia immaculata, an Orthopterous insect from 

 Namaqualand, in which the female is far more conspicuously coloured than the 

 male, 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. Poulton, Mr. Distant, Mr. H. J. Elwes, Colonel Swinhoe, and Mr. 

 Hampson took part. 



Mr. Elwes exhibited specimens of Ribes aureum 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. Distant took 

 part in the discussion which ensued. 



Mr. Barrett exhibited a series of specimens of Noctua f estiva, bred by Mr. Gr. 

 V. Hart, of Dublin, which represented most of the known forms of the species, 

 including the Shetland type and the form formerly described as a distinct species 

 under the name of Noctua conjiua. Mr. Fenn and Mr. Tutt made some remarks 

 on the specimens. 



Mr. W. C. Boyd exhibited a specimen of Dianthoecia Barrettii, taken at Ilfra- 

 combe 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. Grregson's col- 

 lection, which had recently been sent to him by Mr. Sydney Webb. 



Mr. Gr. A. James Rothney exhibited and read notes on a large collection of 

 Indian Ants, which he had made in Bengal between 1872 and 1886, comprising some 

 ninety species. He stated that eighteen of these species had been described by Dr. 

 Mayr in his paper, entitled, " Ameisen Fauna Asiens," 1878 ; he alao said that Dr. 

 Forel had recently identified several other new species in the collection, and that 

 there were about ten species and one new genus which Dr. Forel had not yet 

 determined. 



Mr. H. Gross exhibited, for Mr. T. D. A. Cockerell, of Kingston, Jamaica, 

 several specimens of palm leaves, from the garden of the Museum in Kingston, 

 covered with Aspidiotus articulatus, Morgan. The leaves appeared to have been 

 severely attacked, the scales entirely covering the upper surface in places. 



Mr. F. D. Grodman contributed a paper by the late Mr. Henry Walter Bates, 

 with an introduction by himself, entitled, "Additions to the Longicornia of Mexico 

 and Central America, with remarks on some previously-recorded Species." 



The Rev. A. E. Eaton communicated a paper, entitled, " On new Species of 

 ISphemeridoe from the Tenasserim Valley." — H. Gross, Son. Secretary.
