In mating one clasped the other round the neck with its 

 intermediate legs. The one so clasped turned the end of its 

 body right over its back and so paired. J. F. Perry. 



Teratological Lucanid Beetle. — Mr. Willoughby 

 Ellis exhibited a teratological specimen of the common 

 Lucanid beetle Sinodendron cijlindricum, L., in which the 

 onychium of the right posterior tarsus is much thickened to- 

 wards its apex, and is triangular in section and furnished with 

 three pairs of perfect claws, one pair of the usual size, one much 

 smaller, and one of intermediate size. The insect is a (J, and 

 normal in all other respects. It was taken in the decaying 

 wood of an old walnut-tree at Berkswell, Warwickshire, 

 July 1913. 



Insects captured Feb. 20, 1915, at the flowers op a 

 Eucalyptus at Healesville, Victoria, by Mr. R. Kelly. — 

 Prof. PouLTON said that during the visit of the British Associa- 

 tion to Australia in 1914 he had had the pleasure of meeting 

 and collecting with Mr. Reginald Kelly, of Healesville, near 

 Melbovirne, and he had suggested to this keen naturalist that 

 it would be extremely interesting to capture a set of insects 

 visiting a particular flower at a particular time. He hoped 

 that in this way much light might be thrown upon the com- 

 position of mimetic combinations and the numerical propor- 

 tions of the species entering into them. Prof. Poulton was 

 also very anxious to test the conclusion that members of these 

 combinations visit the same flowers at the same time. Mr. 

 Kelly had kindly acted on this suggestion, and had sent the 

 insects exhibited to the meeting and taken under the condi- 

 tions described as follows by the captor : — 



" The insects sent in spirit and in paper envelopes were all 

 taken on Feb. 20, 1915, on Eucalyptus calophylla rosea — a pink 

 flowering vernacular gum, a native of West Australia, flower- 

 ing in my garden at Mt. Yule, Healesville, Victoria. The tree 

 was crowded with blossom, and is about 20 ft. high with a 

 diameter of about 15 ft. in spread of boughs, the lowest of 

 which are about 4 ft. from the ground. Specimens of leaf and 

 flower are sent, and allowance must be made for these fading 

 to a lighter shade. The large flies [Rutilia] were on the 

 flowers, but rest on the bark of the stem and larger branches
