Entomological Society of London : ith April, 1877. — Professor West- 

 wood, President, in the Chair. i 



Messrs. C. A. Briggs, J. T. Carrhigton, and Or. Harding yreve elected Members ; 

 and Messrs. E. H. BirehaU, Dr. E. Capron, T. D. G-ibson-Carmicliael, and V. Cluse 

 were elected Subscribers. 



The Secretary exhibited a collection of fine species of Lepidoptera from near 

 Bangkok, in Siam, forwarded to him by Mr. R. Q-arner, F.L.S., of Stoke-upon-Trent. 



Mr. McLachlan exhibited a specimen of Ophideres materna, a brightly-coloured 

 exotic species of Noctiddce, given to him by Mr. R. H. Scott, of the Meteorological 

 Office, with a note to the effect that it was taken at sea, in Lat. 25° 24' S., Long. 62° 

 10' B. (the nearest land being the island of Mauritius, about 360 miles distant), by 

 Capt. Raeburn, of the ship " Airlie." The moth is a common Indian species, but is 

 found also in Africa. A specimen was long ago recorded from Brazil, and Mr. Grote 

 had recently noticed its occurrence in Florida. He also exhibited the cocoon and 

 pupa of a species of Cetoniidce (probably Diplognathus silaceus) from Camaroons, 

 sent to Mr. Ruthei'ford. The cocoon appeared to be formed of dark brown earth, 

 but attached thickly to the exterior were oval, slightly flattened, deep black hard 

 bodies (each nearly 5 lines long, by 2 broad), which he thought were probably the 

 dung of some rodent animal. 



Mr. Champion exhibited Stenus Kiesenioetteri (hitherto only found in this 

 country at Wimbledon), Gymnusa bremcollis, Bembidium nigricorne, and Flocio- 

 merus luridus, all taken by him at Chobham, and Philonthus cicatricosus from 

 Shoreliam. 



Mr. H. Vaughan exhibited (on behalf of Mr. Bidwell) an example of Nofodonta 

 trilophus, taken about the year 1867 by a lamplighter, at Ipswich. Mr. Douglas 

 bred the species many years ago from a larva found near St. Osyth, and there had been 

 other records of its capture in this country, but more or less of vague authenticity. 



Professor Westwood read a letter addressed to him by Mr. B. Gr. Colo respecting 

 the subject of seasonal dimorphism in Lepidoj)i era, and giving the results of an 

 experiment he had made with Ephyra punctaria. The greater number of moths, 

 the produce of one brood of eggs, appeared in July, and were of the spotted variety, 

 but the remainder did not emerge till the May following, and resembled their mother 

 in all respects. Mr. Cole alluded to Dr. Knaggs' remarks apropos of Selenia illus- 

 traria, published in Ent. Mo. Mag., vol. iii, p. 238, as beai-ing upon the same subject. 

 He considered it probable that individuals that remained the longest time in the 

 pupa stage would produce the most highly vitalized imagos. Mr. McLachlan 

 alluded incidentally to the Lepidoptera brought home by the Arctic Expedition from 

 the far north (82° N. latitude), and said that the larva; of most of these species must 

 of necessity require more than one season to acquire their full growth, for the short 

 fitful summer was utterly inadequate for the full development of most of the species ; 

 and, futhermore, it was probable that the pupa state might habitually last several 

 years. 



Professor Westwood read notes on the species of StylopidcB, which had the 

 habit (exceptional for the Family) of living upon a species of Honwpiera, found at 

 Sarawak ; and exhibited drawings illustrating the paper. He also read notes on the 

 genus Prosopisioma, esDccially with regard to the species from Madagascar described 

 by Latreille, and of which he possessed the types, whicli were exhibited. 



Mr. Cameron connnunicated a paper on East Indian species of Tenthredinidce. 

 Mr. A. G-. Butler communicated the first portion of an enumeration of the Lepi- 

 doptera of the Amazons, collected by Dr. Trail in the years 1873 — 1875. Mr. Baly 

 communicated descriptions of new species of Ualticida. Mr. C. O. Waterhouse 

 read a Jlonograph of the Australian species of Lycida. Mr. Smith read descrip- 

 tions of new species of the genera Pseudomyrma and Tetraponera.
