interested with the insects of this particular region: and 
the Eev. F. D. Morice suggested that, speaking from a Hvmen- 
opterist’s point of view, he would not have the least difficulty 
in distinguishing the Lepidoptera from the Pompilids, and 
that in the Sahara region, where some models abound, none of 
the Lepidoptera exist at all. 
Mr. A. Sicu, Dr. T. A. Chapman, and other Fellows also 
joined in the discussion. 
Variation in Xanthia ocellaris. —Mr. E. D. Nevinson 
showed bred series of Xanthia ocellaris, developing three 
distinct aberrant forms, and examples of X. fulvarjo, and X. 
yilvago for comparison, the exhibit demonstrating the apparent 
transition from one species to the other through the typical 
and variant forms. The only other series bred from British 
ova by Mr. Mills in 1908 displayed no variation of any kind, 
and were all typical specimens. 
British Anthrocerids. —The Hon. X. C. Eothschild e.x- 
hibited a number of Anthrocerids captured in Great Britain, 
and called attention to some remarkable specimens secured at 
Ashton Wold, Oundle, which belonged to the form known as 
Anthrocera hippocrepidis. The exhibitor also showed some 
enormous specimens of A. filipendulae from the same locality, 
and pointed out that this large race had apparently exter¬ 
minated A. hippocrepidis in a locality where that species had 
only recently appeared. 
Commenting on Mr. Eothschild’s exhibits, Mr. J. W. Tutt 
said that Anthrocera hippocrepidis, Stphs., was the most elusive 
and least known of the British species of the group. It bore 
certain superficial resemblances to Anthrocera irifolii-minor 
and A. filipendxdae, the particularly being prone to smaller 
size and five-spottedness, by losing the 6th (lower outer) spot 
on the upper-side, the larger and, in the most developed 
specimens, strongly six-spotted and scarcely, if at all, different 
superficially from A. filipendidae. Like Mr. Eothschild, he 
also found the insect confined to rough pastures, and also with 
a tendency to die out in one spot and appear in a similar at no 
great distance. It was usually on the wing in June, early or 
late, according to season, but, in the same season well ahead 
of A. filipendulae. He had already included details of its life-
