as well as minute insects of all other families. 



We stock various Sizes and lengths of these Silver Pins, 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).
