Lord Walsingham exhibited a series of the larger and more striking species of 

 Xyloryctinae, a sub-family of the G-elechiidae, especially characteristic of the Austra- 

 lian fauna. The series illustrated the life-histories and the great disparity in colour 

 and form between the sexes of many species. He also gave an account of the family, 

 chiefly from notes by Mr. Dodd, of Queensland, with especial reference to the habits 

 of the larvse, which live in holes in tree-trunks, to which they drag leaves in the 

 night for the next day's consumption. Mr. Grahan, a locust, Acrydium CBgyptium 

 (= tartaricum), taken in a house in Hanover Square, and probably imported in 

 vegetables. Mr. Kirkaldy, species of water-bugs, including Enicocephalus culicis 

 and Gerris rohustus, both taken for the first time in Mexico. A discussion arose on 

 the reported occurrence of the San Jose scale, Aspidiotus perniciosus, in Great 

 Britain. Mr. K, Newstead stated that during nine years' work on Coccidce, he had 

 never once met with this species among scale-insects taken in this country and sent 

 to him for identification. It was impossible even for an expert to distinguish it, 

 without careful microscopical preparation and examination, from among the thirty 

 or more known species of Aspidiotus, and any attempt to identify it on imported 

 fruit by naked-eye observation, or with a hand-lens, was, therefore, quite imprac- 

 ticable. The risk of its distribution by being imported on fruit was small ; there 

 was, however, much more likelihood of its introduction on plants. At the same 

 time, he saw no reason to suppose that it would be more injurious in this country 

 than the common Mytilaspis pomorum ; in America the San Jose scale had several 

 generations in the year, sometimes as many as five, but in this country it would 

 probably conform with the habits of all other scale-insects at present investigated, 

 and become single-brooded. — W. F. H. Blandfoed, Son. Secretary.

GTMNASPIS, n. g. 

 ? puparium without larval exuviae or secretion ; composed en- 

 tirely of the naked moulted skin of the second stage ? . ^ puparium 

 with larval exuviae and secretionarj margin as in Aonidia. 



GrTMNASPIS ^CHME^, n. Sp. 



$ puparium composed entirely of the naked moulted skin of the 2nd stage $ , 

 which completely envelopes the adult insect, as in Aonidia and Fiormia ; high 

 convex, more or less circular, anal extremity usually pointed ; margins produced and 

 convex, entire, or constricted at the spiracles ; the constrictions irregular and fre- 

 quently assymetrical ; irregularly and widely punctate ; shining bronzy-black, opaque, 

 very strong ; the ventral surface as much so as the dorsal. The ventral surface is 

 usually covered with a delicate white secretion, which bears impressions of the leaf- 

 structure, and sometimes projects a little beyond the margin of the puparium.
