GEOGRAPHICAL DISTRIBUTION OF VEGETATION IN 

 YORKSHIRE. 



A paper of the greatest interest and value to botanists, bear- 

 ing the above title, bv Dr. Wm. G. Smith and Mr. C. E. Moss, 

 appears in the April number of the ' Geog"raphical Journal' of 

 the Royal Geographical Society. This forms Part i of the 

 Botanical Survey of the County, and deals with a portion of 

 the West Riding extending from Penistone to Keighley north- 

 wards and from Todmorden to Castleford eastwards. It is 

 illustrated by nine photographs and accompanied by an excellent 

 map, coloured to show the distribution of the dominant types of 

 vegetation ; the map is a half inch to the mile reproduction oi 

 the field maps prepared during the progress of the survey. 

 A limited issue of special reprints with text, and cloth-mounted 

 map, pocket size, will shortly be available, and may be obtained 

 from Messrs. J. Bartholomew & Co., Edinburgh, or from the 

 authors. We hope to give a detailed notice of this paper in 

 our next issue. We understand that Part 2, which will deal 

 with the Harrogate to Skipton district, will probably be ready 

 in June. 



BEETLES AND ELECTRIC LIGHT. 



E. G. BAYFORD, 

 Barnsley. 



Artificial light has long been known as an attraction for 

 moths, and lepidopterists have used this knowledge to advantage 

 in their quest of certain genera. Other orders of insects are 

 attracted, although in a lesser degree, beetles amongst them. 

 At the beginning of the collecting season it may be as well to 

 draw the attention of coleopterists residing in areas where the 

 electric light has been installed to this fact. A little time 

 devoted to a careful examination of the standard and the 

 ground within a radius of nine feet around it will not be 

 altogether thrown away. My time for observation during- 1902 

 was very limited, and the results consequently meagre. The 

 following notes will, however, indicate the minimum of success. 

 The families principally represented are the Carabidae and 

 Lamellicornia. There is something ludicrous in the sight o'i 

 a wingless Carabus nemoralis essaving time after time to climb 

 a standard, only to fall as often to the ground. One evening- 

 there was quite a swarm of a comn-ion Amara. These, par- 

 Naturalist.
