a 
(vale) 
and handsome weevil from Mount Quoin, Kaitoke, South 
Island, New Zealand. The specimens were taken by Mr. 
G. V. Hudson, F.E.8., of Wellington, N.Z., at an elevation 
of 3,900 ft., in December 1910. 
A Rare Tortrix.—Commander WaAtLkeEr also exhibited a 
specimen of the rare Tortrix, Phalonia (Eupoecilia) implicitana, 
Wocke, taken by Mr. H. G. Champion at Shoreham, Sussex, 
August 1911. 
A New British Ant.—Mr. W. C. Crawtey exhibited a 9? 
and a 8 of Leptothorax tuberum, Fabr., subspecies corticalis, 
Schenk, new to Britain, found with two larvae in an empty 
beech-nut at Pangbourne, Berks, April 24, 1904. It was 
named by Forel as a var. with long spines. 
A CoccINELLID AND Mimosa Gum.—Mr. N. 8. SENNETT 
exhibited some Coccinellids as found on Mimosa trees, and 
read the following note :—‘‘ J have here for exhibition several 
specimens of Chilocorus bipustulatus which I took recently at 
Mont’ Estoril in Portugal. On examining the small exuda- 
tions of gum on the Mimosa trees, I discovered these beetles, 
presenting what I take to be a remarkable though hitherto 
unrecorded case of Protective Mimicry, feeding and resting 
on the bark in considerable numbers, and I procured speci- 
mens of the bark and a number of the beetles, which I have 
mounted as I found them. It will be noticed that the narrow 
transverse reddish band about the middle of each elytron gives 
to the insect a remarkable semblance of semi-transparency 
which perfectly coincides with the appearance of the globules 
of gum. I have also included in this case a few specimens of 
the lichen which is abundant on all these trees, and amongst 
which the beetles probably find the Aphides on which they 
subsist. As far as I am aware, the Mimosa tree is not 
indigenous to Portugal, but it is, of course, quite possible 
that the beetles were introduced with the trees. It would be 
interesting to find out why this particular species requires 
protective disguise, as the Coccinellidae as a family would 
appear to be remarkably immune from the depredations of 
enemies.” 
Mr. G. C. Cuampron observed that the species was a native 
of Britain and not uncommon.
