this gall is produced by a distinct species of gall-fly, or only

makes it impossible to refer it to one of the previously 
described galls (Forstinsekten, iii. 56, pl. v., fig. 8).—G. ZL.

Notes on Preserving Larve. By Henry A. Aun, Esq. 
ALTHOUGH the mode of preserving larve for the cabinet is 
familiar to many practical entomologists, there may be a 
few who read this journal to whom the method, simple as it 
is, may be unknown. Specimens are often seen pickled in 
bottles of spirits; but treated thus they seldom form very 
beautiful objects, and, enclosed in tubes and vials, cannot be 
arranged side by side with the imago forms. Therefore, to 
know how to preserve larve in such a way that they may be
