T[04 ^v. Mr. KirbyV Cont'iHualion of the 



On the twenty-fecond of June I obferved another Ichneumon (w), 

 not uncommon, piercing the florets of the wheat. This fpecies did 

 not appear to infert its aculeus between the valvules of the corolla, 

 but to pierce the glumes of the calyx; to effcd which purpofe it is 

 armed with a very fhort one fub-cxerted : of this I found both the 

 fexes; the male was dirtinguiihed from the female by its large eyes, 

 placed very near each other, with reticulations unufually vifible. I 

 prcfnme this to lay its eggs in the larvae, but have not been able pofi- 

 tively to afcertain the fa6t. Upon the fame day that I firft obferved 

 this fpecies, our Ichneumon Tipulce made its appearance in great num- 

 bers ; a ftrong proof that the larvae were now generally hatched. 

 Concernino- this Ichneumon I have no new remarks to offer, except 

 that it muft introduce itfelf within the floret to come at the larvae, 

 as appears from its mode of laying its eggs (x): fo that thefe three 

 enemies of the 7'//K/a have each a different method of attacking it. 

 The firfl: undermines its little fortreis, the fecond makes a breach in 

 the walls, and the third carries it by ftorm (jO- 



Amono-ft the infedls of other genera that I particularly noticed 

 upon the wheat this feafon, the Aphh granaria (z) was common; as 

 was likewife a fpecies of C'lmcx in all its ftates, but I could not per- 

 ceive that it devoured our Tipula. It anfwers in fome refpedls to 

 C. lateralis of Fabricius {a\ but in others it differs much from it : 

 I fhall add a defcription of it to the others at the end of this letter.

( y) On the fourth of July I f.iw another Ichneumon inferting its aculeus into a floret of 

 wheat, but it evaded my endeavours to take it. It feemed much too large to have any 

 connedion with our Tipula.
