i8C PROCEEDINGS OF THE 



extensive brush-maker in the north of the city ; and exhibited 

 specimens. 



A letter from Mr. House was read, detailing the method by 

 wliich he had succeeded in rearing a Hybrid, between Smerin- 

 thiis Ocellatus and ^S*. Populi, accompanied by two specimens. 

 The upper wings were those of the latter, the under ones those 

 of the former species ; and these characters were constant 

 thoughout all the specimens reared. The antennae were half- 

 pectinated, and the new insects exhibited a singular mingling 

 of the characters, not only of their two parents, but of the two 

 sexes likewise. 



A Paper by Mr. Westwood, on Amblythyreus rhombiventris, 

 a new exotic Hemipterous insect, was read. 



Some remarks from Mr. Children, on the autumnal dis- 

 ease of Flies, supposed by Mr. MacLeay to be of the nature 

 of a Fungus, in contravention of that opinion, were read. 



A Paper by Mr. Ashton, illustrated with drawings, on the 

 wings of Hemipterous Insects, and the curious apparatus, of 

 two distinct constructions, by which their wings are united 

 together in flight, as in Hymenoptera, — by which the last-named 

 order was deprived of the sole right to their title, — was com- 

 municated. 



A Letter from Mr. Raddon was read, with specimens of a 

 small Moth, found to be extremely destructive in granaries at 

 Bristol, and begging the communication of a remedy. The 

 letter stated that turpentine was of no use, for the knots and 

 other most resinous parts of the skirting and floors appeared to 

 be the favourite morsels of these infesters. The application of 

 Kyan's Patent was suggested by Mr. Waterhouse. 



A communication from the Earl of Derby, with a feather 

 of a Harpy Eagle, in his possession, infested with a species of 

 Pediculus. They were seen, when alive, running in and out 

 of the quill of the feather, by a very minute hole they had 

 made near its root.
