Notes and Comments. 339 



THE PREVALENCE OF ANOPHELINES. 



In connexion with possible risks of malaria being acquired 

 in this country, the Local Government Board are anxious 

 to collect as much information as possible at the present time 

 regarding the prevalence and distribution of anopheline 

 mosquitos in various parts of the country. Naturalists and 

 field entomologists could give much valuable help in the 

 matter : — (a) by keeping notes and records, beginning at once, 

 of any adult insects which they may meet with during natural 

 history searches, etc., and also of the detection of anopheline 

 larvae ; (b) by forwarding any information on the subject 

 already in their possession. 



RECORDS. 



In making records the following are important : — 

 Adults : Date. 



Hour of collection. 



Place (if in a building, specify its nature). 

 Condition of weather and temperature. 

 Whether few or abundant. 

 Larvee : Date. 



Hour of collection. 



Locality. 



Nature of collection of water (natural or 



artificial) . 

 Nature of breeding place (shady pools, open 

 collections of water ; presence or absence 

 of weed, fish, etc.). 



IDENTIFICATION. 



As regards differentiation of anopheline from other species 

 reference may be made to the British Museum pamphlet on 

 Mosquitos (Economic Series No. 4, British Museum ; Price id.) 

 or, of course, to any larger text books. In case of doubt as to 

 the identity of insects collected, specimens may be sent for 

 identification by post addressed (O.H.M.S.) to the Medical 

 Officer, Local Government Board, Whitehall, London, S.W. 1., 

 and marked on the cover ' Entomologist.' Letters relating 

 to investigations (a) and (b) above should be similarly addressed. 



PHENOLOGICAL OBSERVATIONS. 



From Messrs. J. E. Clark and H. B. Adames, we have 

 received their valuable Report on the Phenological Observations 

 in the British Islands, from December, 1915, to November, 1916, 

 reprinted from the Quarterly Journal of the Royal Meteorological 

 Society. From this we learn that : — ' When, in 1892, Mr. 

 Mawley took over from the late Rev. T. A. Preston responsi- 

 bility for the Annual Report, he entirely re-organised its 



1917 Nov. 1.
