on the Continent and as a British insect. He pointed out 
that here as elsewhere in the world the normal host was 
Lasius umbratus (and mixtus). He mentioned that he had 
visited the locality in Oxfordshire both with Commander 
Walker and Mr. Collins where these Coleopterists had taken 
the beetle very sparingly with Lasius niger. On these occa- 
sions the beetle was not found, but he had discovered a small 
colony of LZ. mixtus there, showing that the normal host did 
occur in that locality. 
BritisH ANERGATES ATRATULUS, ScoH.—Mr. W. C. CRAWLEY 
exhibited 3, virgin 9, fully developed fecund queen, and a 
partly-developed queen of Anergates atratulus, Sch., taken 
for the first time in Britain, July 1912, in the New Forest. The 
original queen of the colony lived in captivity for nine months, 
and died owing to rough handling while moving the ants to 
afresh nest. The queen, unable to walk owing to the enormous 
dilatation of the gaster, is pulled from place to place in the 
nest by means of the claws on the fore-legs of the Tetramortum 
caespitum 83. The partly developed queen was fertilised 
in the nest, and accepted by a large colony of T. caespitum, 
and she was assiduously tended by the %% for nine months, 
when she died owing to an accident when changing the nest. 
Immediately after her adoption, the Tetramorium 3% killed 
their own 99 and gd, thus showing how the Anergates is 
accepted and the host queens eliminated. Previous experi- 
ments by myrmecologists on the Continent had only shown 
that the Anergates may be received into the nests of Tetra- 
morvum, but none had ever lived more than a few days or had 
been treated by the Tetramorium %% as their queen. The 
solution of this problem may possibly throw some light on 
the question of the elimination of the host queen in the case 
of other parasitic ants. 
A SINGLE BATCH OF CELASTRINA ARGIOLUS EMERGING IN 
AUTUMN AND SPRING.—The PrestDENT showed thirty-three 
specimens of Celastrina argiolus bred from one batch of eggs, 
sixteen of which emerged last autumn and seventeen in May 
of this year. They had all been bred by the Rev. C. R. N. 
Burrows on Portugal laurel. The autumn emergence (which 
had been shown to the Society previously) were unusually
