THE ENTOMOLOGIST. 295 



hornet was providing building-materials for its nest, as he had 

 invariably found this to be composed of friable paper, appa- 

 rently formed from dead or decayed wood. Upon referring 

 to Reaumur's ^ Memoires' he found that that keen observer 

 had recorded a precisely similar circumstance, and he, Mr. 

 Smith, was inclined to think the insect was endeavouring to 

 extract the sap, from the inner wood, as food. 



Parasite of the Peacock. — Mr. Dunning exhibited a para- 

 site, 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, who, in Gerraar's 

 * Zeitschrift,' actually gave Linne's name as a synonym, for 

 what reason he knew not. 



Malformation in the AntenncB of Lejpidoptera. — 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) Sco- 

 pelosoma satellitia in the same condition, and, in this speci- 

 men, the corresponding eye was enveloped in a cuticle. He 

 also exhibited Melitaea Cinxia, with malformed hind wings. 



Galls of Campanula rotundifolia. — Mr. Muller communi- 

 cated 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 Cam- 

 panula rotundifolia, 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 appropriated by the gall, 

 and one specimen presents a terminal cluster of thq^n. 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, of a 

 flattened form, have the centre of the body longitudinally 

 purple-red, and the remaining parts almost transparent. At
