the species were readily distinguishable by the position of 

 the androconia on the nervures, and by this test the insect 

 was shown to be ^. niohe. 



Prey of an African Asilid. — Mr. S. A. Neave exhibited 

 a large series of insects, 1326 in all, forming the prey of a 

 common Asilid, PromacJms fasciatus, including Lepidoptera 

 91, Ck)leoptera 279, Hymenoptera 334, Orthoptera 55, Rhyu- 

 chota and Homoptera 132, Neuroptera 4, and Diptera 361, of 

 Avhich no less than 101 were other, or in a few cases, the same, 

 species of Asilid. H ■ also exhibited an example of a Mantis, 

 Polyspilota pustulafa, Stal, preying upon the large Asilid, 

 Hyperechia consimilis, Wood. 



Mr. Neave received the thanks of the Society for this 

 interesting and laboriously collected exhibit. 



A SCARCE British Neuropteron. — Mr. W. J. Lucas ex- 

 hibited a specimen of Drepanepteryx pkalaenoides, Linn. 

 (Order Neuroptera), taken about the end of July 1914, by 

 Mr. E. A. C. Stowell, B.A., at Bexhill. It was foimd sitting 

 very quietly on the glass of a street lamp between 10 and 

 11.30 p.m., on the outskirts of Bexhill about three-quarters 

 of a mile from the sea. It so closely resembles the Hook-tip 

 Drepana falcataria that its captor took it for that species. 

 For a Neuropteron it is fairly large ; but still this was only 

 about the twentieth specimen that had been captured in 

 Britain. Apparently it seldom flies in the daytime, and may 

 on that account escape notice. Judging by the date of 

 capture of various specimens its period of flight is a long one. 



A MOVABLE MICROSCOPIC STAGE. — Dr. H. ElTRINGHAM 



exhibited a little machine of his own invention consisting of 

 a mechanical stage specially adapted for the microscopical 

 examination of pinned insects, and so contrived as to admit 

 of the insect on its pin being turned completely round on both 

 a vertical and horizontal axis, without its departing from 

 centre of the field or the focal plane. 



An Australian Lycaenid larva resembling the flower 

 OF THE " Wattle," on which it feeds. — Prof. Poulton 

 exhibited the flowers of an Acacia, probably A. haileyana, 

 F. V. Muell., together with a female Lycaenid, Nacaduba 

 hiocellata, Feld., and the pupa-case from which it had emerged.
