1856 ("Ent. Annual," 1857, p. 77), and it was recorded in 

 1863 ("Ent. Annual," 1863, p. 113) as having been taken 

 by Dr. Power at Wey bridge with Formica rufa, and by 

 Douglas and Scott near Croydon with Formica sanguinea. 



Mr. H. St. J. Donisthorpe heartily congratulated Mr. 

 Bedwell on his capture and remarked on the scarcity of the 

 species in this country. He said it was more abundant 

 abroad, that the principal hosts were Formica fusca, F. 

 sanguinea with F. fusca as slaves, and Polyergus rufescens 

 with F. fusca as slaves. It was also found with F. rufa, 

 pratensis, exsecta, rufibarhis, Lasius flaxms, niger, fuliginosiis, 

 Tajjinoma erratica, Leptotliorax acervorum and Myrmica scahri- 

 nodis. The geographical distribution was London to Gibraltar 

 in the west, and as far east as the Caucasus. 



Ants from North Britain. — Mr. H, St. J. Donisthorpe 

 exhibited {a) specimens of Formica exsecta ($ and ^ ^), 

 several nests of which he had discovered near Aviemore in 

 Inverness-shire in May. He pointed out that it had never 

 been recorded from Scotland or the North before, and showed 

 a map of the British Isles to illustrate the British distribution 

 of the species. The localities at present known for it are 

 Aviemore, Bewdley in Worcestershire, New Forest, Parkstone, 

 Bournemouth, as far west as Poole and as far east as Ring- 

 wood, Parkhurst Forest, Isle of Wight, Bovey Tracey in 

 Devonshire, and the Land's End in Cornwall ; also (b) specimens 

 of Formica i^ufa-jyratevisis, ? ?, ^ ^, pseudogynes and micrer- 

 gates from Nethy Bridge, Inverness-shire, and remarked that 

 this was the chief form there. He described the nests, and 

 mentioned that a number of them were being extinguished 

 by the undergrowth. Moss starts to grow round the base of 

 the nests, then " bilberry " and heather which creep upwards 

 all round the hillock, gradually driving the ants to the summit 

 and eventually extinguishing the colony. Professor Wheeler, 

 in a paper " On Relations of Ants to Plants," i-ecords similar 

 cases in America and Europe, and is of opinion that the colony 

 eventually dies off. 



Mendelism in Abraxas Grossulariata. — Mr. L. Doncaster 

 exhibited a drawer of Abraxas grossulariata and its var, 

 lacticolor, illustrating breeding experiments.
