any rate occasionally, notwithstanding all that had been said and written to 

 the contrary. 



Mr. Dunning exhibited a parasite, which he had recently taken from a 

 peacock. This was evidently the Pediculus pavonis of Linne and the older 

 authors ; but, by all recent writers on these insects, it was termed 

 Goniodes falcicornis of Nitzsch ; and Nitzsch, in Germar's ' Zeitschrift,' 

 actually gave Linne's name as a synonym, for what reason he knew 

 not. 



Mr. Lewis exhibited examples of antennal malformation in Lepidoptera, 

 comprising (1) a specimen of Melitsea Cinxia, in which the apical half of 

 one antenna was aborted ; (2) Cymatophora diluta, with one antenna 

 congenitally wanting ; and (3) Scopelosoma satellitia in the same condition, 

 and, in this specimen, the corresponding eye was enveloped in a cuticle. He 

 also exhibited Melitsea Cinxia, with malformed hind wings. 



Mr. Butler exhibited examples of Ccenonympha Satyrion from the 

 opposite sides of the Gemmi. These individuals showed marked variation, 

 and he thought it probable they represented the ordinary condition of the 

 species on either side of that mountain-pass. 



Mr. Albert Midler communicated the following notes on a Cecidomyia, 

 causing galls upon Campanula rotundifolia : — 



"Mr. James W. H. Traill, of Old Aberdeen, has sent to me several 

 specimens of Campanula rotundifolia, Linne, gathered by him in August 

 last on exposed braes, two or three miles to the north of that city, 

 which specimens are infested by the larvae of a Cecidomyia. They occur 

 both in the seed-vessels and in green, small, globular, monothalamous 

 axillary galls, developed from buds. On some shoots almost every bud is 

 appropiated by the gall, and one specimen presents a terminal cluster of 

 them. Mr. Traill has suggested to me that the galls are, probably, 

 abortive flower-buds, and I am inclined to concur in his opinion, owing to 

 the presence of the larvae in the seed-capsules as well. One of the latter 

 disclosed an immense number of unripe seeds, each one tenanted by the 

 very young oval-larva, the smallest quite white ; older ones 1 milhm. in 

 length, flattened, the centre of the body longitudinally purple-red, the 

 remaining parts almost transparent. Kt this stage the larvae looked very 

 pretty in the seeds, of which they had consumed the contents, presenting 

 the appearance of living rubies, cased in flat capsules of transparent horn. 

 Adult larvae — taken singly from "the galls, and in number from the seed 

 capsules — were 3 millim. in length, 14-jointed, elongated, reddish, with 

 darker intestine ; their first segment very slender, beak-like. In the full 

 grown state they were lively ; but in the earlier stages they appeared rather 

 sluggish. I regret that mildew killed the whole brood ; but I hope, with 

 Mr. Traill's kind assistance, to rear the perfect insect this season. In the 

 meantime I propose for it the name of C. Campanulas, as its peculiar mode
