292 THE ENTOMOLOGIST. 



Lamostenua complanatiis, from the neighbourhood of Dublin — taken iu 

 June, 1902. — Mr. W. J. Kaye exhibited examples of Heliconhis lindiyii, 

 H. antiochus, and MorpJio achilles, from British Guiana, with notches 

 taken out of the hind wings, presumably by birds ; to illustrate that 

 these distasteful or warning-coloured species are subject to attack, this 

 helping to show that experimental tasting, as propounded by the 

 Miillerian theory of mimicry, does exist and go on. — Professor L. C. 

 Miall, F.E.S., communicated a paper by Mr. T. H. Taylor, M.A., 

 entitled "The Tracheal System of Simnlmm." — Professor Augusta 

 Forel, M.D., communicated a paper entitled "Descriptions of some 

 Ants from the Eocky Mountains of Canada (Alberta and British 

 Columbia) collected by Edward Whymper." — Dr. T. A. Chapman 

 read a paper entitled "On Heteroyynis paradoaa." — H. Goss and 

 H. EowLAND- Brown, Ho7i. Secretaries. 



October 15i/t.— Professor Edward B. Poulton, M.A., D.Sc, F.E.S., 

 Vice-President, in the chair. — Mr. A. J. Cliitty showed an entirely 

 black specimen of Metoecm paradoxus, as tending to disprove the 

 mimicry suggested by him at the meeting on Oct. 1st. Dr. Chapman 

 said that in his experience one out of every six specimens of this 

 species was black. Mr. Donisthorpe stated that out of about one 

 hundred specimens he had never caught or bred a black Metoecus. — 

 Mr. E. P. Pickett exhibited a variety of the female of Aryynnis aylaia, 

 varieties of Satyms iairira, and a long series of Lyccena corydon, taken 

 near Folkestone and Dover in August last, including four males of 

 the last-named species, with the black band on the edge of the fore 

 wings much deeper than usual ; also twelve dwarf male specimens of 

 this species, four dwarf females, and many other aberrant forms. 

 Mr. Goss said this dwarf form of L. corydon occurred constantly, 

 according to Mr. Sydney Webb, in one valley about two miles east of 

 Dover, but he was unaware of its regular occurrence elsewhere in 

 this country. He remarked that a dwarf form of L. ariun occurred 

 wherever the type was found, both in Gloucestershire and Cornwall. 

 Professor Poulton, Dr. Chapman, and Mr. Sloper also remarked on 

 the dwarf forms of L. corydon. — Dr. Chapman exhibited specimens of 

 Notodonta (Hybocawjni) dryinopa from Queensland. It was remarkably 

 similar in appearance, structure, and habits to Hybocampa milhauseri 

 (see ' Entomologist,' 1889, and p. 43 of 1902). He stated that the 

 pupa with a similar spine to that of H. milhauseri does not cut out a 

 regular oval lid from the cocoon like that species, but by a stabbing 

 process pierces it with a number of holes, so that a piece is more 

 easily pushed off. The cocoon being covered with bits of bark, stone, 

 &c., a cutting process would be impossible, whereas the cocoon of 

 H. milhauseri was of pure gum-like silk. He pointed out that the 

 larva much resembled that of H. wilhanseri, but the hinder segments 

 were more like those of Stauropus fayi. He also exhibited living eggs, 

 larvfe, and imagines of Orina tristis var. smaragdina, from Pino, Lago 

 Maggiore. The beetles, since they were taken on May 30th, had laid 

 many eggs. Dr. Chapman said that the embryo, ready to hatch, might 

 be seen within some of the eggs, and its hatching spines observed. 

 Mr. Sloper exhibited a specimen of Lycana hylas, said to have been 

 caught at Dover on the 7tli September last. — Mr. Martin Jacoby com- 

 municated a paper entitled " A further Contribution to our Knowledge
