he tliouglit the genus, although of very wide distribuliou, had not jireviously been 

 noticed in that countrj. Mr. Clmnipion said that lletiicocephalus was generally 

 recognised as a type in itself of a family, and Mr. Kirkaldy that it was much com- 

 moner than generally supposed. It w;is probably only an aberrant form of the 

 ReduviideB having no stridulating apparatus on the presternum. Mr. C. P. Pickett, 

 a series of Smerinthiis tilia\ bred during May, 1900-1, including one male speci- 

 men having the right upper wing banded, tlic left wing with the two ordinary spots; 

 a banded female ; a male with only one spot ; and a richly coloured female. Mr. C. 

 Gr. Barrett, imagines, cocoons, pupa skins, and also water-colour sketches of larvae, 

 reared and drawn by Miss Frances Barrett, at Buntingville, Pondoland, South 

 Africa, including Hesperia keltloa, Leucaloa eugraphica, Liparis pulverea, Leiio- 

 dora montana, Trabele ochroleuca, Chilena prompta, Braura ligniclusa, Eutricha 

 pithyocampa, DuUcJda fasciata, Porela ^obria,.£hanidophora phedonia, Sphingo- 

 morpha chlorea {Monteironin). Dr. A. Jefferis Turner, specimens of Australian 

 wood-boring Lepidoptera belonging to four different families. They included — 

 I't/ralidcB : Doddiana xi/Ioryctis, Turn. GeJechida : Crgpiophasa Jfavolineata, and 

 C. hemipsila. Turn., Maroga mythica, Meyr., M. setiotricha, Meyr., Uzucha 

 horealis, Turn. CossidcB : Dudgeona actinias, Turn., Xyleutes pulchra, Eoths., X. 

 Macleayei, X. nephocosma, Turn. HepialidcB : Charagia mirahilis, Eoths., C. 

 ramsayi, Seott, and C. cyanochlora, Lower. Mr. H. Goss, for Mr. Ernest Ardron, 

 of Colombo, Ceylon, two specimens of a species of Fhylliuni {PhasmidcB). They 

 bore an extraordinary resemblance to leaves. He also showed three varieties of the 

 male of Melitcea Cinxia, which he had taken on the 27th and 28th of May at 

 Niton, Isle of Wight. Mr. C. O. Waterhouse, two new genera and species of 

 CoJeoptera recently described by him in the Ann. and jMag. Nat. Hist, from Rio 

 Janeiro. One belonged to the aberrant PrionidcB {Pathoceriis Wagneri) ; the other 

 {Tetraphalerus Wagneri) belonged to the Cupesida, and was remarkable for the 

 form of its head. He also exhibited ^ and ? of the curious Scarabaid, Glyphoderes 

 sterquilinus, Westw., from North Argentina. Mr. II. St. J. Donisthorpe, a glove 

 burnt by discharges of formic acid in the nests of Formica rufa. In connection 

 with the apparatus exhibited at the last meeting to determine the strength of this 

 acid, Professor Poulton said that the discharges collected in the tubes fluctuated 

 greatly in strength, the strongest yielding a proportion of 60 to 70 per cent, of 

 anhydrous acid, a drop of which placed by Mr. Holroyd on the back of his hand 

 left a distinct scar some days after the application. The discharge of Dicramira 

 vinula, he added, showed a strength of about 45 per cent., and Mr. F. Merrifield 

 remarked that in breeding the larvse the acid liberated by this species left a yellow 

 stain on the leno, making it rotten. Mr. W. Schaus communicated " A Eevision 

 of the American Notodontidce," and Mr. H. St. J. Donisthorpe read a paper on 

 " Cases of Protective Eesemblance, Mimicry, &c., in British Coleojjtera." Professor 

 Poulton said that the facts were admitted iii the Lepidoptera, and it was interesting 

 to see how far they were borne out in the Coleoptera. The CeridcB mimicked 

 other distasteful Coleoptera, e.g., the Cantharidce ; the Lamiidw of Borneo were 

 mimicked by other Coleoptera, and on the whole it would be found that the 

 parallelism of facts between Lepidoptera and Coleoptera was far greater than 

 anticipated. The Eev. Canon Fowler, Sir Greorge Hampson, Mr, G. C. Champion, 

 and Mr. E. Trimen continued the discussion.— H. Eowland Beown, Hon. Sec.
