NOTES AND OBSERVATIONS 



Mouse Eating Aphides. — Is this a well- 

 known fact in natural history ? Yesterday 

 I noticed a common house mouse running 

 up the creepers on the house, eating the 

 Aphides off the roses. It did not seem at 

 all disconcerted by our presence, though we 

 watched it quite close for a long time. I 

 have never heard before of mice being use- 

 ful in cleaning roses. — E. A. B., Whitehall, 

 Sandback. 



Captures at Darenth. — On Whit Mon- 

 day, 29th ult., I and my brother, Mr. T. 

 Marriott, had an entomologising ramble 

 through Darenth Wood, Dartford. It was 

 a beautiful day, and insects were fairly 

 plentiful. The following list is the result of 

 our captures : — G. rhamni, 3 ; P. napi, 4 ; 

 P, raped, 1 ; A cardamines, 3 , A. euphrosyne, 

 ig ; H. alveolus, 5 ; H. tages, i ; P. pliloeas, 

 I. This latter is a variety new to me : it 

 has four or five blue spots above the copper 

 band in the hind wings. 11 V. tnaculata. 

 Beating the underwood yielded G. pusaria, 

 I ; A. remutata^ 8 ; A. candidata, 2 ; I. lacte- 

 aria, i ; P. petraria, 5. On searching the 

 oak trunks we obtained C. corylata, 2 ; T, 

 bitmdulata. 5 ; and T. punctulata, 10. A. 

 euplirosyne and Y. maculata were in great 

 numbers flying all over the wood, and had 

 we been disposed we could have taken many 

 more. — C. A. Marriott, ii, George Lane, 

 Lewisham, Kent. 



BRITISH BIRDS, THEIR 

 NESTS AND EGGS. 



By S. L. Mosley. 

 Genus II. Musicapa. 

 Muscicapa, Musca (L), a fly ; Capio (L), I 

 seize. 



Only two species are native of Britain, 

 and two or three others have occurred as 

 visitors from the Continent. The bill is 

 rather stouter than in the warblers. They 

 live almost entirely upon flies, which they
