CLUMP, DURING THE HOT HOURS OF THE DAY. — Prof. Poulton Said that 



he had received only that morning a letter from one of their Fellows — 

 Mr. C. F. M. Swynnerton, Game Warden of the Tanganyika Territory ; 

 and he wished to call the attention of the meeting to the interesting 

 observations recorded by the writer. 



Aberrations of Brenthis Euphrosyne and B. selene. — The 

 Secretary exhibited on behalf of Mr. B. G. Adams a magnificent 

 collection of aberrations of B. euphrosyne and B. selene, all taken in 

 different years in a restricted locality in N. Devon about 600 ft. above 

 the sea. Amongst these were two specimens which appeared to be 

 hybrids, the upperside of one being that of B. euphrosyne with the 

 underside of B. selene, the opposite being the case with the other speci- 

 men. The two species often overlapped. 



Diptera from Norfolk. — Mr. J. E. Collin exhibited the following 

 interesting species of Diptera captured on Blakeney Point, Norfolk, from 

 July 16th-24th, 1920. 



Hercostomus praetextatas, Haliday. Described in 1855 from a single 

 male captured in July, 1854, on the Sandhills of Rossbegh Point, 

 (Kerry), and never rediscovered in Britain until Dr. Winifred E. 

 Brenchley found two females at Blakeney Point in August, 1919, a 

 discovery which led to the search for and capture of both sexes in some 

 numbers this year. 



Pipunculus mini hi us, Becker. A species new to the British List 

 not hitherto considered distinct from P. litioralis, Becker. 



Lininophora aestuiim, Villeneuve. Also new to the British List. 

 Mr. H. W. Andrews has found this species in Ireland, and there were 

 one or two unidentified specimens in the Verrall Collection. It was a 

 common species among the Psamma growing on the sandhills at 

 Blakeney. 



Lininophora maritima v. Roder. This name so far as the British 

 List is concerned has been wrongly applied to the next species. The 

 females were common on the sandy mud left exposed by the retreating 

 tide, but only three males were captured. 



Lininophora virgo, Villeneuve. Only a single female of this 

 interesting species was captured among the Psamma growing on the 

 sandhills. The name is new to the " List," though previous British 

 records of L. maritima apply to this species. 



Lininophora biseriata, Stein. A recently (1916) described species 

 which was fairly common on the Psamma -covered sandhills. It is an 

 addition to the British List. 



Tetanops myopina, Fallen. A sea-coast and sand-hill Ortalid not 

 often found in collections and the only representative of the genus in 

 Britain. 



Papers. — The following papers were read : — " Butterfly Migration 

 in British Guiana," by L. D. Cleare, F.E.S. " Preliminary Note on 

 the Interpretation of Insectan and Myriopodan Structures, through a 

 Comparison with the Structures of Crustacea," by Prof. G. C 

 Crampton, Ph.D., F.E.S.
