at Land's End. Also Uropoda philoctena fastened on the strigil 

 of an hermaphrodite of the same ant from the same locality. This 

 species is new to Britain. — Mr. C. 0. Waterhouse, larvae of a species 

 of Hypoderma received from India from Mr. J. E. Middleton, with a 

 note that they had been taken from a gazelle and were probably an 

 undescribed species. Mr. Waterhouse expressed the strongest doubts 

 as to the possibility of determining a species of Hijpoderma from 

 the larv£e. There is, however, no Indian Hypoderma described 

 hitherto. — Mr. E. Enock, a photomicrograph of a new species of 

 Mymar, which he has named M. regalis, accompanied by one of 

 M. pulchelhis for comparison, captured June 3rd, 1911, at Burnham 

 Beeches. Not only are the posterior wings greatly elongated into 

 a very narrow battledore with six long hairs on the lower margin, 

 but the anterior wings are surrounded with sixty long hairs — 

 instead of the thirty-five of Mymar pulclicllus. — Mr. fi. Eowland- 

 Brown, some drawers of Miss Fountaine's bred series of African 

 Charaxes. — Dr. Chapman, a box of insects to illustrate a case of 

 mimicry, remarking that in March and April, both at Hyeres and at 

 Amelie-les-Bains, his attention was attracted to a Reduviid bug, 

 Pirates hyhridus, Scop. He followed up one or two on the wing, 

 taking them for Pompilid Hymenoptera, and when they settled on 

 the ground their movements were precisely those of Pompilus when 

 hunting on the ground — sharp, active, jerky, and taking wing at 

 once if alarmed. The red colouring on the elytra was, when 

 running, much like the red of a Pompilid body between or under the 

 wings. On picking up the bug, it often occurred that one was stung, 

 about as sharply as many Pompilids do, and some are fairly pro- 

 ficient therein. The sting was of course the thrust of the beak or 

 proboscis, of which not a few Reduviid bugs can make effective 

 weapons of defence. The sting enhances the resemblance to an 

 Aculeate. Dr. Chapman also observed that at Hyeres, on March 

 29th, 1911, he found, on turning over a stone, under its edge a small 

 nest of Polistcs gallica. The nest consisted of eight small cells, in 

 each of five of which was one egg. It could not have been founded 

 very long. Under it (above it before the stone was turned over) 

 there rested not one female but two females side by side. The 

 advancement of the nest showed that it was impossible for one of 

 these to be a worker reared in the nest. The question was, were 

 they working together, or was one only a casual visitor, taking 

 shelter during the inclement weather ? In the latter case, would it 

 not have been regarded and treated as an enemy, instead of both 

 resting together in a thoroughly friendly way ? Dr. Chapman also 

 exhibited some well-grown larvae of CallopJirys avis from the Riviera. 

 — Professor Poulton, on behalf of Mr. A. H. Hamm, assistant in the 

 Hope Department of the Oxford University Museum, a case of insects 

 illustrative of certain associations of mimetic British Hemiptera- 

 Heteroptera, with their hymenopterous models, the chief object being 

 to record that the Hemiptera are to be found in the localities 

 frequented by their models, and often in their company. Field 

 observations are especially important on the mimics of insects, such 

 as the Hymenoptera-Aculeata, with extremely characteristic habits
