Mr. G. A. J. Eothney sent for exhibition and communicated 

 notes on a number of species of ants collected by himself in 

 Australia, in May and June, 1886, which had recently been 

 named for him by Dr. Forel. The collection included : — 

 Camponotus niyriceps, Smith ; Melbourne. C. (rncojnlusus, 

 Mayr ; Adelaide. C'. 7iov(b Holhindice, Mayr ; Adelaide and 

 Brisbane. Iridoinijrniex purpureus, Sm., ^ and c? ; at Adelaide, 

 Melbourne, and Brisbane. I. rufoniijer, Lowne ; Adelaide and 

 Brisbane. /. gracilis, Lowne ; Adelaide and Melbourne. 

 I. itinerans, howne; Adelaide. Ectatoiiuna metalliciuii, Sm., 

 5, j; common at Adelaide, Melbourne, and Brisbane. 

 This is a very beautiful ant when seen alive, its metallic 

 colours being strikingly brilliant in the sunlight. The pro- 

 minence of metallic-coloured ants in Australia is very 

 noticeable to anyone fresh from the Indian fauna. E. 

 nudatam, Mayr; Adelaide, and E. mayrl, Emery. ; Brisbane, 

 are also nice species. Apluejior/aster loiujiceps, Sm. ; with its 

 nests in the earth generally under stones, is a common species 

 occurring at Albany, Adelaide, Melbourne, Sydney, and Bris- 

 bane. Polyrhachis anuiwn, Fab., dacinali, Mayr, guerini, Koger ; 

 the last a very pretty species, are all common at Brisbane. 

 Myrmecianigriventris, Mayr, and nigrocincta, Sm. ; two species 

 of " bull-dog " ants, occur near Brisbane. Mr. Eothney said 

 that there is a pale-coloured local race of the curious long- 

 legged ant, Leptoiityniiexerythrocephalus, Fabr., from Brisbane, 

 and a variety of Camponotus rtibiginosus, Mayr, " variete toute 

 noire," also from Brisbane. He also sent a few species from 

 Honolulu S. I., taken during the two or three hours' stay of 

 the S.S. 'Mariposa'; the little cosmopolitan ant, Solcwipsis 

 geminata, Fab., was extremely common, its nests being under 

 stones, pathways, almost everywhere : there is also a Mono- 

 morium which Dr. Forel has not yet determined, and which 

 is probably new. 



Papers read. 



Mr. C. 0. Waterhouse read a paper entitled " Some Obser- 

 vations on the Mouth Organs of Diptera," which was 

 illustrated by numerous diagrams. A long discussion ensued 

 in which Mr. Champlou, Mr. McLachlan, Mr. Jenner Weir,
