" EUDIOPTES INDICA. 



" Expansion of the wings 10 — 12 lines. Anterior wings hyaline, with a broad, 

 dark brown band along the costa and hinder margin, the band rather widening 

 as it approaches the anal angle : posterior wings hyaline, with a band of the 

 same width and colour as on the anterior wings along its hinder margin, 

 gradually tapering as it approaches the anal angle. 

 " Larva smooth, pale grass-green, with the head yellowish. 

 " Feeds on the Gossypium herbaceum, and on the Corallodendron ; common in 



Java from January to April, according to Dr. Horsfield. 

 " This species is nearly allied to Pyralis hyalinata, Lin., but is nevertheless quite 



distinct. 

 " Three other species of insects attack the cotton plants in the East Indies, and 

 cause serious injury, viz., 



" The larva of some beetle, probably of the family of the Chrysomelidae ; an Aphis, 

 for which I propose the name A. Gossypii ; and the immature state of a Homopte- 

 rous insect, probably related to the family Cercopida;. 



" I trust that this notice, imperfect as it is, may be of some use as a first step to- 

 wards a history of the insects injurious to the cotton-plant, and may bring the impor- 

 tant subject to the notice of entomologists, who have opportunities of witnessing the 

 ravages committed by insects on the cotton-plant, and induce them to record their 

 observations, with a view of furnishing materials for a more complete investigation of 

 the subject hereafter."

The President announced that in addition to the donation of lithograph copies of 

 the portrait of the late Rev. W. Kirby, for the ' Transactions,' Mr. Spence had placed 

 fifty copies at the disposal of the Council, who have determined to offer them to mem- 

 bers and subscribers at one shilling each. 



The President also said he had been requested to announce that Mr. Foxcroft in- 

 tended to visit Wales this year, on an entomological expedition, for which he solicited 

 subscriptions, to be repaid by his captures.
