at Matley Bog. Although I arrived at Lyndhurst about the usual time for Mallota 

 cimbiciformis Flu., and Callicera renea, F., I did not see either, and a few days later 

 on meeting Dr. Sharp lie told me they were over, as he had previously taken both, 

 but had not seen any more about for quite a week. The two C. renea mentioned 

 were quite late specimens, and showed signs of having been about for some time, 

 one being taken on 8th September, which I think is the latest date yet reported 

 To my surprise, not a single Ceroplatus tipuloides, F., and only one Spi/ogaster 

 uliffinosa, Fin., turned up at Fern Cottage, both species having been commoner 

 there than usual the previous year. — F. C. Adams, 3t», Ashley Gardens. S.W. :

The Reports to the Malaria Committee of the Royal Society. — The sixth 

 series of these Reports, issued early in March, is of great importance from an ento- 

 mological, as well as from a medical, point of view. The Reports are from Drs. 

 Stephens and Christophers, the medical officers who are investigating the subject 

 in Bengal, and deal principally with the power, or otherwise, of different species of 

 Anopheles to transmit malarial fever. The district they had under consideration 

 extends from the Bay of Bengal to the "Duars," a narrow strip devoted to tea 

 cultivation, at the foot of the Himalayas. They found five species of Anopheles 

 in this district, but only one of them, A. Christophers!, Theobald, proved of im- 

 portance as an infecting agent, and this is almost confined to the " Duars." A. 

 Rossi, Giles, which swarms in Calcutta, proved there of negative importance; spe- 

 cimens fed purposely upon malarial patients failed absolutely to produce within 

 them the malarial organisms, whereas of A. Christophers! in the "Duars" from 

 40 to 72 per cent, of individuals were infected, and thus able to transmit the 

 disease. In the plains of Bengal A. Rossi does not seem quite so immune, as 

 from 7 to 12 per cent, were infected. The fever cases at Calcutta would seem to be 

 mainly importations. No. 450 (March 7th, 1902) of the " Proceedings of the Royal 

 Society " contains a systematic monographic list of the Culicida of India, by Mr. 

 F. V. Theobald, M.A., F.E.S. The author makes the significant suggestion that 

 whereas it is only certain species of Anopheles that carry malaria, it may be that 

 certain species of Culex may do so likewise. — Eds. 



Hyetodesia vagans, Fin., confirmed as British. — In Mr. Verrall's New List of 

 Diplera this species is omitted, and in the January No. (ante p. 8) of this Magazine 

 he includes it with seven other species unknown to him. This is an oversight on 

 Mr. Verrall's part, as I submitted specimens to him some years ago. Tt is a per- 

 fectly well-known species to me, as it is represented in my cabinet by three males 

 and eight females, besides others given away. Mr. C. J. Wainwright also has some 

 half dozen in his collection. All these were taken in Sutton Park, Warwickshire. 

 Mr. Verrall now admits the validity of the species.— Ralph C. Bbadley, Moseley,

Lopus flavotnarginatus, Don., in Blean Wood, and Paraaus bicolor at St. Mar- 

 garet's Bay.— I find that on the 24th of June, 1900, I captured two specimens of 

 the apparently rare bug, Lopus fiavomarginatus, Don., in the Blean Woods. They
