DESIDERATA. 



I am at present engaged in working out the life-history of Xestobium tessella- 

 tion, an insect that has done a great deal of damage to the roof of Westminster 

 Hall. As the matter is one of great interest to the public, I should be very 

 grateful for any assistance ; living beetles or affected timber being required for 

 investigation.— Jamk.s W. Munro, Imperial College of Science and Technology,

It would be a great convenience to the Editors in keeping the accounts if 

 these were paid promptly, as having to send reminders entails a considerable 

 amount of extra work.

SILVER PINS FOR COLLECTORS OF MICRO-LEPIDOPIERA, &c, 



as well as minute insects of all other families. 



We stock various sizes and lengths of these Silver Pius, which have certain 

 advantages over the entomological pins usually employed. 



For instance, insects liable to become greasy and verdigrisy, like Sesiidae, are best 



pinned on Silver pins, which will last much longer than the ordinary pins (whether 



enamelled black, or gilt, or silvered). 



We shall be pleased to send pattern cards on application.
