tlie serrated fore margin of the tegmina by means of which the stridulation 

 is effected. 



Mr. Wood-Mason also stated that it might interest the members of the 

 Society to hear that in the course of his anatomical work he had discovered 

 a remarkable case of viviparity in the Orthoptera, in a large cockroach 

 belonging to the genus Panesthia, the species of which inhabited the 

 tropical forests of Southern Asia and of Australia, where they lived in 

 the rotten wood of fallen trees. The species in question was P. Javanica, 

 from the abdominal brood-pouch of the female of which he had extracted 

 young white specimens of 6-5 mm. in length, and these, from their being 

 already provided with legs, antennae, black eyes, and the full number of already 

 hard-tipped gnathites, as well as from their size, he judged were just on the 

 point of birth when the mother was thrown into the alcohol. He further 

 suggested that the curious and as yet unexplained habit evinced by several 

 European species of Blattida of carrying their egg-capsules about with 

 them for a week, or even for so long a period as a fortnight, before depositing 

 them, might possibly be explicable us the retention of a vestige of a lost 

 viviparity.

Mr. F. Smith called attention to a passage in Mr. M'Lachlan's " Report 

 on the Linnean Collection," read at the last meeting {vide also Ent. Mo. Mag. 

 for November, p. 140), wherein the author states, as the result of his 

 examination of the collection, that " there were no traces of mites, Psoci, 

 or Anthreni." Mr. Smith was of opinion that this statement might lead to 

 the belief that he had affirmed that the collection was actually attacked by 

 mites, Psoci, and Anthreni, and as this was not the case he mentioned the 

 subject in order to remove any erroneous impression. 



Mr. C. 0. Waterhouse exhibited a specimen of ChauUognathus excellens, 

 a new beetle from the United States of Columbia. 



Mr. H. T. Stainton exhibited a new horn-feeding Tinea reared from 

 horns from Singapore, T. orientalis, allied to the well-known large species 

 from South Africa, of which the larvae fed in the horns of living buffaloes 

 and antelopes, and which had been described by Zeller under the name of 

 Vastella, and subsequently by himself under the name Giyantella, both
