188 THE ENTOMOLOGIST. 



Britain, which he had caught in Norfolk, and bred from fir-cones 

 gathered in the same locality. Mr. Meyrick read two papers, 

 "On Pyralidina from Australia and the South Pacific" and 

 "Descriptions of some exotic Micro-Lepidoptera." In these 

 papers about sixty new species were described. A discussion 

 ensued, in which Dr. Sharp, Mr. Stainton, Mr. M'Lachlan, and 

 otliers took part. Mr. Meyrick stated that, as far as the Pyralidina 

 were concerned, Australia could not be regarded as a separate 

 region, for a large number were not endemic, but appeared to have 

 been introduced from the Malay Archipelago. The method of 

 this immigration seemed doubtful. Mr. Meyrick was of opinion 

 that the insects flew very long distances, and effected a settlement 

 through their food-plants being widely distributed and common. 

 He instanced the undoubted immigration of certain Australian 

 species into New Zealand, a distance of 1200 miles. Mr. Stainton 

 adduced the instance of Margarodes unionalis, which is a South- 

 European insect, feeding on the olive, yet is occasionally found 

 in Britain. Mr. Meyrick exhibited, in connection with his paper, 

 Oxychirota paradoxa, Meyr. (unique specimen representing the 

 family Oxychirotidse), Epliarpastis dcedala, Meyr., and Mixopkyla 

 erminea, Moore. Mr. Meyrick also made some observations on 

 the distribution of the insect fauna in the various regions of 

 Australia ; he said that it appeared to be more or less different in 

 certain defined portions of the continent, which might be roughly 

 regarded as oases in the midst of desert districts ; all his 

 observations, however, had tended to upset Mr. Wallace's theory 

 that Eastern and Western Australia were originally separated, as 

 the gradations in the insect fauna from east to west were quite 

 gradual ; in Western Australia the Tineina were the only group 

 well represented by peculiar endemic forms. Mr. Pascoe read a 

 paper " On the genus Byrsops,'' a genus of Curculionidae. The 

 President announced that Lord Walsingham's collection of Lepi- 

 doptera and larvae, recently presented to tlie nation, would be 

 exhibited in the Hall at the Natural History Museum, South 

 Kensington, until the end of June.— W. W. F.
