fure incomplete; | This arofe from our beginning our obfervations - 
too late in the feafon, after the parent fly had difappeared. Deter- 
mined to watch its progrefs this year from the firft appearance of 
the ear, my: fuccefs, i in moft refpeéts, has been anfwerable to my ex- 
pe&tations. have not indeed yet been able to afcertain the male of 
our Tipzla; but to make fome amends for this difappointment, I have 
had an opportunity of obferving all the motions of the female, and 
befides have difeovered'two new fpecies of Ichneumon, which, in con- 
jun&ion with that known before, and defcribed in the laft volume

neumon Tipule, fcem to be intrufted with the i important office of re- - 
ftraining within due limits the numbers of that very deftructive 
little animal. |

into form the different memoranda which I have by me on this fub- 
ject, having adhered faithfully to the Linnean maxim, Nulla dies fi ne
