to the ears of the animal, in the orifice of which it breeds and feeds 

 so fatally that it is very common to see one or both ears of the ass 

 lopping over the face, vi^ithout power in the animal of ever again 

 raising them. This injury is called by the natives ' Clabaud.' How 

 fast the insect breeds may be inferred from the quantity of eggs in 

 the bottle now exhibited, which were deposited by the two inclosed 

 specimens in the space of three days in a cornet of writing-paper. 

 The specimens were taken from under the tail of a horse. The usual 

 and most efficacious mode of getting rid of this tormenting insect is 

 by anointing its haunts with sweet or other oil ; but the vn-iter adds, 

 that if any better or other mode quicker in its effects and equally in- 

 noxious to the animal could be ascertained, its communication would 

 render a great service to the Haytians. 



He likewise exhibited specimens of the Vegetative Wasp of the 

 West Indies, accompanied by the following note from General Inginac, 

 Secretary to His Excellency the President of Hayti : 



" La guepe vegetale, servant de semence au limoncelle, arbrisseau 

 charge d'epines fort dangereuses, se nourrit de la graine, bien plus 

 volumineuse qu'elle, que produit cet arbrisseau. Des graines du li- 

 moncelle on obtient la cire vegetale qui est tres parfumee. Curiosite 

 naturelle digne d'occuper 1' attention des naturahstes. Le limoncelle 

 croit en abondance a St. Jague." 



Specimens of the vegetable wax mentioned in the note were also 

 exhibited. An extract from the 'Family Library,' No. 51, ('The 

 Natural History of Insects,' vol. ii., p. 296,) was also read, giving a 

 detailed account of the vegetative wasps. The German work, ' Der 

 Naturforscher,' was also upon the table, in the fourth number of 

 which (tab. iv.) the plant is represented with two of the wasps laying 

 upon the ground on their backs and three flying round the tree, with 

 the vegetable matter growing out of the base of the abdomen. 



Mr. Hearne also exhibited a specimen of spider- silk, produced 

 from the Nephila clavipes, a large West Indian species, the webs of 

 which are very strong, and are supposed by Mr. MacLeay (in his 

 Memoir upon Mygale pubhshed in the ' Transactions of the Zoolo- 

 gical Society') to have been regarded by the early voyagers as those 

 of Myfjale avicularia, whence has arisen the incorrect notion that the 

 latter are bird-killing species. According to Mr. MacLeay, the web 

 of the Nephila is sufficiently strong to hold a small bird if caught 

 in it. 



The same gentleman also exhibited a very large species of Mygale 

 from the same island. 



Mr. Ingpen exhibited twigs of apple and jasmine trees infested 

 with Cocci; in the former the young minute Coed were observed
