Hijlory of Tipiila Tn'tld. lat 



but as I had brought them down fo far as to connedt them with 

 thofe made lafl: year («), this interruption was of lefs confequence. 



Before I take leave of this part of my fubject, and give fome ac- 

 count of the Ichneumons mentioned above, I mufl: obferve that the 

 female of I'ipula 'Trhici approaches very near to the female of one 

 defcribed by GeofFroy (o), which Fourcroy and Villars after him 

 have called Tipula immaculata. His definition of that inledl, " atra 

 bUs nheis" and his defcription in French, anfwer exaflly to a minute 

 black Tipula, which I find common upon the wheat, remarkable for 

 its beautiful plumofe antennoe (p). The female, he obferves, is very 

 different from the male, and it is ncceflary to have feen them copu- 

 lating, not to make of it another fpecies. It is lliort, thick, yellow, 

 with black eyes [q). He fpeaks of his infe<£l as common in gardens,. 

 a fituation in which I have never found Tipula Tritici. This defcrip- 

 tion certainly approaches very near to our female, yet the colour of 

 that is deep orange, and not yellow : befides, he makes no mention 

 of the beautiful prlfmatic hues which adorn the wings. The black 

 male, mentioned above, difappears at the fame time with our female 

 of the wheat, but it agrees in no refpetSl with the fpecimen you re- 

 ceived from Mr. Markwick: befides, I found another black one, 

 which appeared to me to be its female. 



I fhall now proceed to give you fomc further account of the in- 

 feiSts which prey upon I'lpula Tritici. I have reafon to believe, as I

(p) Le male de cette petite efpece eft allonge comme les precedens, avec le ventre 

 mince et en filet. Sa couleur eft partout d'un noir matte. Ses antennes forment ile 

 beaux plumets. Ses alles font d'un blauc laitcux, qui fc fait d'autant plus remarquer 

 que fon corps eft fort noir. 



(7) La femelle eft tres differente, 5; il faut les avoir vu accouples enfemble pour nVn 

 pas faire une autre efpece. Elle eft courte, grode, dc couleur jaune, avec les yeux noirs. 

 On.trouve cette Tipule partout dans les bofquets des jardins.
