Entomological Society of London : Uh Septemler, 1877. — Peofessoe 

 J. O. Westwood, M.A., F.L.S., President, in the Chair. 



Mr. F. Smith exliibited a fine collection of Hymenoptera, collected near Cal- 

 cutta last season by Mr. Kothney. There were new species of Cerceris and ApidcB, 

 and fine SphegidrB, &c. lie called attention to Chlorion lubatum, the habits of which 

 have been graphically noticed by Mr. Rothney, ante p. 91. 



Mr. McLachlan exhibited enlarged drawings (made during a recent visit to 

 Brussels) of the extraordinary insect from Java, described by Wesmael in 183G, as 

 Himantoptertis fuscinervis, and placed by him in the Lepidoptera : the insect remains 

 unique in the Brussels Museum. In 1866, Hagen (Hemerob. Synopsis Synony- 

 mica) transferred Himantoptertis to the Neiiroptera as a sub-genus of Nemoptera. 

 The mouth parts and legs wei-e wanting when Wesmael first described the insect ; 

 but from the form of the body, neuration, clothing of the wings as seen under the 

 microscope, &c., Mr. McLachlan had no doubt whatever that the insect is Lepidop- 

 terous, and should come near to Thi/mara Zoida, E. Doub., from North India, near 

 which he found Mr. Butler had located it (from the figure and description) in the 

 British Museum. Professor Westwood stated that in 1876 he had also made 

 drawings of the insect, and agi'eed with its position near Thi/mara* 



Mr. McLachlan also exhibited leaves of various large species of Acer growing 

 in the grounds of M. van Yolxem, at Laeken, near Brussels. Although many of 

 the trees were over 50 ft. high, nearly every leaf was marked with large whitish 

 blotches, being the mines of a small saw-fly {Pkyllotoma aceris, Kaltenbach). The 

 insect only appeared for the first time last year, and was now in such extraordinary 

 abundance as to threaten serious damage to the trees. 



Professor Westwood exhibited minute species of the curious Hymenopterous 

 genus Mymar from Ceylon. Also the sexes of a curious species of Cetoniidce from 

 the NeQgherries, sent to him by Mr. Wood-Mason ; it was first described in 1842, 

 in the "Arcana Entomologica," and had remained almost unique. 



Mr. Wood-Mason exhibited the sexes of a rare species of Indian ManlidcB 

 {Phyllothelys Westwoodi), the $ of which is remarkable for the possession of along 

 frontal horn, absent in the <J . He also exhibited drawings of a stridulating spider 

 (Mygale slridulans) from India ; and a stridulating scorpion of large size ; both sexes 

 of this stridulated, and the sound could be artificially produced in dead specimens 

 preserved in alcohol. Finally, he exhibited a Homopterous insect, collected by 

 Colonel Godwin- Austen (who was present), in Bangalore, to the abdomen of 

 which a larva was attached at the last segment by a transparent cord. He thought 

 the larva was Lepidopterous, but there was some difference of opinion as to this : 

 he handed the specimen to Professor Westwood for examination. 



Mr. Wormald exhibited (for Mr. W. B. Pryer) a small but interesting collection 

 of Butterflies from North China. 



Mr. Champion exhibited FacTiyta sexmacidata, a new British Longicorn {vide 

 ante, p. 92), and other rare Coleoptera from Avicmore, Inverness-shire. 



A letter was read addressed to the President by Mr. Grevelink, of the Hague, 

 respecting damage occasioned to cocoa-nut trees in the West Indies by various insects. 



Mr. Jenner Weir stated that he had recently bred a single fenuile of Lasiocampa 

 quercus, which was kept so that no male could possibly have gained access to herj 

 and was killed within twenty-four hours of emerging, and yet a number of eggs laid 

 by her proved fertile, and he had the larvaj now feeding. 



The Secretary exhibited an exotic Longicorn, which had been found alive at 

 Birkenhead. 



Mr. J. W. Slater read " Vivarium notes on some common Coleoptera."

 the Coiuptc Keudu uf the Belgian Kntmuological Society. — R. McL.
