 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 (Forslinsekten, iii. 56, pi. v., fig. 8). — G. L.

Notes on Preserving Larva. By Henry A. Auld, Esq. 



Although the mode of preserving larvae 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 larvae in such a way that they may be
