Mr. M. Jacoby brought for exhibition a specimen of Mega- 

 lopus melvponoi, Bates, an insect which so much resembles a 

 bee that Bates had said they were indistinguishable in nature. 

 Professor E. B. Poulton remarked that the species recalled 

 a little black Trigona from Borneo, recently discovered there 

 by Mr. R. Shelford, but in this case the mimic was not of a 

 stinging but of a biting model. 



Mr. A. Bacot exhibited on behalf of Dr. Culpin specimens 

 of Papilio macleayanus and Hypocista metirius captured in 

 Queensland, illustrating the use of " directive " markings in 

 the Rhopalocei-a in influencing their enemies to attack non- 

 vital parts. All the specimens were taken on the same 

 occasion, and the fresh condition of the Papilio was in marked 

 contrast to the specimens of another species recently exhibited 

 by Prof. Poulton, to show that the tails were not always the 

 first portion of the wings to be lost. 



It was noticeable that two out of the six specimens showed 

 signs of an attack directed at the lobes of the hind-wings, 

 situated at the base of the tails, and judging by the unset 

 specimens, that these lobes were roughly suggestive of a head 

 when the insect is at rest. In the other species eight out of 

 the seventeen specimens showed damage at or near the small 

 ocelli on the upper or under side of the hind-wings. 



Mr. G. J. Arrow exhibited an example of Ceratopterus 

 stahli, Westw., a beetle from Australia possessing notable 

 powers of crepitation. 



Mr. A. H. Jones and Mr. H. Rowland-Brown showed a 

 series of Erebia alecto (glacial is), var. nicholli, Oberth., taken 

 by them at about 8000 ft. at Campiglio, South Tyrol, with 

 specimens of Dasydia tenebraria, var. wockearia, caught in the 

 company of the Erebias in the same localities ; when upon the 

 wing the two species were not dissimilar. Mr. Jones also 

 exhibited examples of Erebia melas from the Parnassus Mount- 

 ains, Greece, for comparison, and fine forms of butterflies found 

 at Mendel, near Botzen, including very large Apatura iris $ $ , 

 Vanessa antiopa, and Satyrus semele. 



Mr. W. J. Kaye exhibited a 9 Morpho adonis from British 

 Guiana together with several males. The female sex is 

 extremely rare, and was only definitely known in 1881,
