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 Réaumut’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 Linné and the older 
authors; but, by all recent writers on these insects, it was 
termed Goniodes falcicornis of Nitzsch, who, in Germar’s 
‘ Zeitschrift,’ actually gave Linné’s name as a synonym, for 
what reason he knew not. 
Malformation in the Antenne of Lepidoptera.—Mr. Lewis 
exhibited examples of antennal malformation in Lepidoptera, 
comprising (1) a specimen of Melitea 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 Melitza Cinxia, with malformed hind wings. 
Galls of Campanula rotundifolia.—Mr. Miiller 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 larve 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 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 larve 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
