Ilaemonia appendiculata, Panz., taken in an affluent of the River 
Cherwell, near Kidlington, Oxon., August, 1910; also {d) a 
specimen of Cryptophagus suhdepressus, Gyll, from Wytham 
Park, Berks, with the right antenna duplicated from the third 
joint. 
Life Tenacity op Abyssinian Beetle.— Mr. W. F. H. Rosen¬ 
berg showed a living beetle of the genus AlindiHa, received in 
a collection of preserved Coleoptera fi’om Abyssinia. The 
specimens were rolled up in small paper cylinders, and when 
they were opened the insect was found to be alive. The 
collection must have been despatched from Abyssinia at least 
a month before the opening of the package. The insect has 
the habit of simulating death on being alarmed, which probably 
accounts for the collector having packed it up without noticing 
that it was alive. 
Living Ants and their Nests. —Mr. H. St. J. Donisthorpe 
exhibited two nests of ants to illustrate his observations on 
the founding of nests of Formica ritfa by a ^ of that species 
in nests of Formica fusca, and also made some remarks on 
what he had observed in nature, both with F. rufa and F. 
exsecta. He had observed a 9 '^’ufa in Pai’khurst Forest on 
May 15th, running about near the entrances to a fusca nest. 
The 9 fought with some of i\\e fusca, and eventually entered 
one of the openings in the ground used by the fusca. On 
May 27th, in company with Mr. E. R. Bankes, he found a small 
nest of F. exsecta at Bournemouth, which on being investigated 
was found to contain many 9 ? of F. fusca. 
Exhibit Nest No. 1 consisted of 9 9 oi F. rufibarhis y. fusco- 
rufibarhis, and a 9 of rufa. This was exhibited to the 
Society on March 2nd, when the rufa 9 (which had been 
obtained at Nethy Bridge in May 1909) had just been accepted 
by the fusco-rufibarbis 9 (sent to him by Mr. Keys from 
Whitsand Bay in July 1909) after having been introduced 
into their nest. From March 7th to April 4th the 9 
eggs, and larvae hatched by May 1st; these were fed and 
attended to by the 9?- June 1st many changed to 
pupae, nearly all being naked. By June 20th some of the 
pupae hatched, and on July 20th all had hatched. Unfor¬ 
tunately they all died, the 9 ? uot having sufficiently removed
