sunset, and in spring and autumn but few will be found after 

 ten o'clock. Many species visit the sugar about an hour 

 before sunrise in the morning. Sugar is almost useless in the 

 neighbourhood of lime-trees when they are in bloom, and 

 also when there is much honeydew. There is a row of 

 seventeen lime-trees in the field adjoining my garden, and I 

 have sugared the trunks for more than thirty years in every 

 month, except the four winter ones, — November, December, 

 January, and February. Upon these trees I have captured 

 nearly every Noctua which occurs in this neighbourhood. —

[I am sure entomologists will be much obliged to Mr. 

 Doubleday for these notes. I believe his experience is 

 greater than that of any other entomologist living. 1 may 

 add, as it is usual for every entomologist to keep a diary of 

 his captures, that the publication of these diaries, or excerpts 

 from them, would be of extreme interest; but they should be 

 prepared in a systematic, and I need not say a careful, 

 manner. I will give an imaginary day: — "Ma}'^ 1st. Wind 

 light, S.S.W. Temperature, 65S Fahr. ; inclining to rain. 



Sugared at Loughton. Captures " The advantages 



of such diaries can scarcely be estimated too highly: coming 

 from eight or nine hundred localities, not only would they 

 show us the exact range of a species, but would also teach us 

 when to expect it, and under what atmospheric conditions. —

Description of the Larva of Euholia periholata. — The 

 eggs were laid in a chip-box on the 18th September, 1874, 

 and the larvae left the egg-shells during the first week in 

 October: they fed in Ulex Europaeus (the common furze), 

 almost exclusively on the blossoms, and after hybernation 

 continued to feed until the end of April, when they had 

 attained their full size; two or three have already spun up 

 between the folds of some muslin in the breeding cage ; two 

 of the larvae are now before me, full fed, yet exhibiting no 

 change of colour or any disposition to spin. The larva rests 

 in a perfectly straight position, but on being touched raises 

 the anterior extremity, arching its back a little; its legs are 

 then directed forwards, and closely appressed together, 

 forming an almost continuous mass with the head. In crawl- 

 ing it makes a very decidpd arch, bending the body nearly
