58 THE entomologist's record. 



former were well past their prime, but the latter were in good condition. 

 For the next month I was occupied with other matters, but Ennomos 

 fuscantaria, Cirrhoedia xerampelina, Citria citraf/o, kept emerging, and 

 I beat a few Leiocampa dictaeoides, Jlrepaiia falcataria, and Platijptenuv 

 lacertinaria from birch in this neighbourhood. On September 2nd, I 

 accompanied a friend to the Norfolk coast, where we found larvae of 

 Enpithecia extensaria in numbers. Tiliacea aura(fo (a very scarce insect 

 here) came to ivy blossom in my garden on September 23rd. Towards 

 the end of October Petasia cassinea emerged well. Out of eighteen 

 larvae I bred fourteen imagines, and of these only two were crippled. 

 I pupated them in a rhubarb-pot filled with earth, in which they 

 could burrow as deeply as they liked. A few Poecilocavijia populi, 

 Hijhernia aurantiaria, and U. defoliaria finished what had been, on the 

 whole, a very fairly good year for insects. 



Trichopteryx intermedia, Gilim., var. thomsoni, 1. B. Ericson, a 



British species. 



By HORACE DONISTHORPE, F.Z.S., F.E.S. 



My friend. Professor Beare and I, took this species in some 

 numbers at Newtonmore, N.B., in June, 1907, by beating fir-tops. 

 I also took two specimens in the debris of a nest of Eonnka mniiinnea at 

 Nethy Bridge a few days later. They have been identified by Isaac B. 

 Ericson, who has now the British Museum Collection of this group in 

 his possession to overhaul. He writes in the Entowolor/isk Tidskrift for 

 1908, pp. 121-126, in a short paper on Swedish Tric/iopterynidae thsitit is 

 distinct from fasicidaris, Herbst, although Ganglbauer (p. 827) gives 

 intermedia, Gillm., as a sj'nonym. He also points out that the type 

 occurs in southern Europe, but that the more north you go a sub- 

 species is formed, which he has called tho)»si>Hi. 



He gives the following species of TricJiopter;/,f as occurring in 

 Sweden: — uraudicollis, Mann., wontandoni, Allib., ni(jricnrnis, Motsch., 

 picicornis, Mann., thoraciea, Waltl., atoiiiaria, De Geer, intermedia, 

 Gillm., V. thomsoni, I.B.E., lata, Motsch., fasicularis, Herbst, 

 cantiana, Matth., snff'ocata, Halid., hrevipennis, Erichs., lomjicornis, 

 Mann., kirhyi, Matth., brevis, Motsch., sericans, Heer, dispar, Matth., 

 and chevrolati, Allib. 



Plebeius argus var. cretaceus, n. var., P. argus var. masseyi, n. 

 var., P. argus var. Corsica, Bell., and Plebeius argyrognomon var. 



Corsica, n. var. 



By J. W. TUTT, F.E.S. 



We are now engaged on a revision of Plebeius anjus (aef/nn), a 

 species that has for 150 years worried entomologists owing to its 

 superficial similarity to P. aniiiroiinomon {anius), and the remarkable 

 variation that it undergoes in its extended range from Sligo in the 

 west to Japan in the east, and from Lapland in the north to the 

 Mediterranean littoral in the south. Almost all authors who have 

 handled the species appear to have fallen into some error or other, and 

 in Staudinger and Rebel's Catalog, 3rd ed., 1901, one still finds some 

 strange results. 



The species is of interest to British lepidopterists, because we have, 

 in the British Isles, at least three very marked races : (1) The smaller.
