THE ENTOMOLOGIST. 



strikingly dimorphic species, the female of which bears some resem- 

 blance, especially on the upper side of the hind wings, to a moth, 

 Myctemera hesperia, of the family Lymantriadai ; and (c) five species 

 of Planema (family Acryeida) and an equal number of species of 

 Pseudacrea (family Nymphalidae) mimicking them, the superficial 

 resemblance being very close in each case. Special attention was 

 called to the specimens of Planema plagioscia, the males of which, 

 with tawny bands on the fore wings, are mimicked by the males of 

 Pseudacrea hobleyi, whilst the females of the Planema with white 

 bands are mimicked by the females of the same species of Pseudacrea. 

 A discussion followed, in which Mr. J. W. Tutt, Mr. G. A. K. Mar- 

 shall, and other Fellows joined. — Mr. H. St. J. Donisthorpe exhibited 

 examples of Methoca ichneumonides, parasitic on the larva of the 

 tiger-beetle, taken by him in the Isle of Wight. He said that it was 

 apparently unknown in this country that Methoca ichneumonides is 

 parasitic on this larva. But he had taken it at Blackgang Chine, 

 where it would be parasitic on G. gernianica. With these examples 

 he also showed the hosts, C. campestris, G. sylvatica, G. germanica, 

 and a tiger-beetle larva. Mr. Donisthorpe also exhibited an example 

 of Ptinella hrita.nnica, Mat., found in a mole's nest at Burwell Fen 

 last month. This is only the third British specimen that has yet 

 been recorded, and apparently the fourth only in Europe, one having 

 been reported from France. — Mr. Norman H. Joy, M.E.C.S., read a 

 paper "On the Behaviour of Coleoptera during Floods," and exhibited 

 living specimens to illustrate the remarkable power of Dianons 

 coerulescens in " skimming " on the surface of water. The following 

 papers were also read: — " A Revision of the genus Diplatys, Serv.," 

 by Malcolm Burr, D.Sc, F.L.S., F.Z.S., &c ; "On the Geometridae 

 of the Argentine Republic," by Louis B. Prout — H. Rowland-Beown, 

 M.A., Hon. Secretary. 



The South London Entomological and Natural History 

 Society. — ^2;riZ lUh, 1910.— Mr. A. Sich, F.E.S., Vice-President, 

 in the chair. — Mr. Ashdown exhibited a large number of Coleoptera 

 taken in Switzerland during July, 1909, including Staphylinus fossor, 

 Tricodes alvcearins, T. apiarius, Spondylis huprestoides, Endomychus 

 coccineus, Molorchus minor, Strangalia attenuata, &c. — Mr. R. Adkin, 

 long series of the various forms of Hepialus humuU, including some 

 very fine Shetland specimens. — Mr. Cowham, portions of ash-stems 

 showing extensive marks of the depredations of a species of Scolytiis 

 beetle. — Mr. Dennis, a long series of photographs of British lichens. 

 — Mr. Turner, a number of species of Lepidoptera sent him from 

 Saskatchewan and Vancouver by Mr. Croker, and commented on 

 their British-like appearance ; included were Argynnis hremneri, 

 Polygonia marsyas, Coenonympha elko, Notolophus badia, Malacosoma 

 pluvialis, Thanaos persius, &c. — Mr. Newman, larvae of Dryas papihia, 

 Melitcsa cinxia, M. athalia, Argynnis adippe, A. aglaia, and Agriades 

 corydon, which he had been forcing. Argynnis adippe and A. aglaia had 

 scarcely responded to the treatment, but the rest were practically all 

 full fed. — Mr. Coote, a bred series of Nyssia hispidaria from ova laid 

 in 1909. —Mr. Sich, the two species of Adela with entire yellow 

 fasciae — Adela croesella (suhella) and A. degeerella — and pointed out 

 their differences.
