16 THE ENTOMOLOGIST. 



Thus the insect was out for some six weeks, but how long in 

 any numbers it is difficult to say. What appeared to be its 

 headquarters was only, as far as I know, worked between July 19th 

 and 26th, except for our trial in August. The only really warm 

 spell in our district this summer was between July 6th and 17th, 

 and doubtless nearly all would emerge then. It would, however, 

 be rash to assign less than three weeks for the period during 

 which they were abundant, — this year at all events. It seems 

 that this season, which has been so abnormal in its amount of 

 sunshine (it always appeared to be raining, too, though the total 

 rainfall was below the average), has not exerted as baneful an 

 influence as might have been expected. The dates of emergence 

 have, of course, been very erratic. Perhaps it will be the coming 

 season that will suffer.

NOTES AND OBSERVATIONS. 



A Proposed Entomological Exchange Club for the British 

 Isles. — At the meeting of the City of London Entomological Society,, 

 held November 4th last, Mr. F. J. Hanbiuy, in accordance with a 

 previous intimation, led a discussion as to the advisability of starting 

 an Entomological Exchange Club for the British Isles on similar lines 

 to the Botanical Exchange Club, which was, and had been, in a very 

 satisfactory position for the past five and twenty years. For the 

 general benefit of those who are disposed to consider whether they 

 would support such a scheme, the following resiuite of the proposed 

 rules and regulations is here set forth : — 



1. The object of the Club is to facilitate the exchange of speci- 

 mens, especially of critical species and varieties. The conditions of 

 membership are that each member shall furnish a parcel of specimens 

 annually, in accordance with the subsequent rules, and pay an annual 

 contribution of five shillings, or of such other sum as may be found 

 necessary to meet the expenses of the Club. He will then be entitled 

 to share in the distribution of specimens made in the early part of the 

 year following that in which his subscription and parcel were sent. 



2. Specimens sent for distribution must be carefully set ; must be 

 in perfect condition (unless the species is particularly scarce and in 

 great demand). Badly set or imperfect specimens will be returned as 

 received to their owners. Species that might be in danger of exter- 

 mination will not be received, except in very small numbers, unless 

 bred ab ovo. 



3. Each specimen must have a clearly written or printed label 

 bearing the name of the species as given in South's list, and must bear 

 locality and date of capture, or date of breeding, and any date obtained 

 that the sender thinks worth while. Specimens sent in each parcel 

 might be arranged in the exact sequence of names adopted in the 

 catalogue before mentioned. Not less than six specimens of each 

 species should be sent, unless very rare or difficult to procure.
