The Zoologist— January, 1868. 1063 



Mr. M'Lachlan mentioned that Dr. Balbiani had recently called the attention of 

 the Soc. Ent. de France to the facility with wbich the silkworm disease might be com- 

 municated to the healthy larva of other Lepidoptera. He had taken larva? of the same 

 brood of Bombvx neustria, and fed some upon healthy leaves of Scorzonera, others 

 upon leaves of the same plant, which he sprinkled with water in which diseased silk- 

 worms had been pounded ; the former were healthy and well developed, the latter 

 were small, soon filled with corpuscles, and died at the first moult. Dr. Balbiani had 

 also inoculated with muscardine the larvae of clothes-moths, by throwing on the infested 

 clothes a powder formed of the debris of muscardined silkworms ; the infection being 

 more rapid and certain when the powder was fresh, less so when dried. 



Mr. Slainton had to record a new habitat for the larva of a Tinea; Mr. Swanzy 

 had shown him the larva-case of a Tinea which was taken from the horn of a kooloo 

 from Natal, and there could be little doubt that the larva must have been burrowing 

 in the horn of the living animal. 



Mr. Swauzy added that, since Mr. Stainton's visit, he had found a living larva in 

 the horn. 



Mr. Trimen had seen the skull of a hartebeest, the base of which was eaten by 

 what he had no doubt was the larva of a Tinea. 



Mr. Trimen exhibited a grasshopper of the genus Pcecilocerus, of which he had 

 found the pupa? in copula : it was not an isolated case, bm he had seen hundreds of 

 pairs of the nymphs at Natal at the beginning of the present year. 



Mr. Trimen exhibited a Mantis with minute fore legs, remarkable for its 

 resemblance to a Phasma. 



Mr. Bates remarked that its likeness to a Bacillus was very close, and suggested 

 that it would be found to feed upon Bacillus, which, deceived by the imitation of its 

 own form, would fall an easy prey to the Mantis. 



Mr. M'Lachlan reported that Boreus hyemalishad been lately taken by Messrs. 

 Douglas and Scotl, amongst moss, near Croydon. 



December 2, 1867.— Sir John Lubbock, Bart., President, in the chair.
