various species of Donacise. Having selected the most likely 

 places, I preijared for wading operations by taking off boots and 

 socks, and turned up my trousers, — the best way to ensure 

 success if Donacise are at all obtainable. My captures were as 

 follows : — Seventy-five specimens of Donacia linearis and D, 

 tJialassina, four D. comari, two D. sericea, eight D. sagittaria, and 

 six D. hydrochcei'idis, — in all one hundred specimens. Other 

 captures were Liiia longicollis, Cassida viridls, Colymhites tesselatus 

 (from old tree stumps), Phyllopertha horticola, Gyrinus mariniis, 

 Luperus betidinus (ver}'^ common), Erirhinus nereis (profusely), 

 and other small species. — G. A. Lewcock ; 40, Oxford Road,

Entomological Society of London. — Jime 1st, 1887. Dr. 

 David Sharp, F.Z.S., President, in the chair. Mr. Philip Crowley 

 exhibited the following specimens of Diurni, from the Kareen 

 Hills, Burmah: — Papilio zaleucus, Hew., Papilio adamsoni, Smith, 

 Papilio ? sp. (male and female), and Nymphalis nicholii, Smith. 

 Mr. T. R. Billups exhibited several specimens of an ant found at 

 Kew, frequenting a species of palm from Tropical Australia, and 

 which had been determined as Tapinoma melanocephalum ; also 

 living specimens of Cardbus auratus from the Borough Market, 

 and of a species of Blaps from Northern Africa. Mr. Waterhouse 

 exhibited a specimen of a Brazilian Locust, Conoceplialus ? sp., 

 which he had for some time preserved alive, and which had only 

 died that same morning. He called attention to the change of 

 colour which he had observed in the eyes of this insect ; in a 

 bright light they were dirty white or horn-coloured, with a black 

 dot in the middle ; but at night, or if the insects were confined in 

 a dark box, they became altogether black ; shortly after death, 

 also, the eyes became black. Mr. M'Lachlan observed that he 

 had noticed a darker spot in the centre of the eye in certain 

 Ephemeridse, and in other Neuroptera. The discussion was con- 

 tinued by Dr. Sharp and others, but no one seemed to be able to

 specimens of Cateremna terehrella, Zk., a species lately taken in
