but as I had brought them down fo far as to conne& them with 
thofe made laft year (^), this interruption was of lefs confequence. : 
- Before I take leave of this part of my fubject, and give fome ac- 
‘count of the Jchneumons mentioned. above, I muft obferve that the 
female of Tipula Tritici approaches very near to the female of one 
defcribed by Geoffroy (2), which Fourcroy and Villars after him 
have called Tipula immaculata. His definition of that infe&, * ara 
alis niveis, ' and his defcription i in French, anfwer exa&ly to a minute 
` black Tiula, which I find common upon the wheat, remarkable for ` 
its beautiful plumofe antennz (5). The female, he obferves, is very 
different from the male, and it is neceffary to have feen them copu- 
lating, not to make of it another fpecies. It is fhort, thick, yellow, 
with black. eyes (7). He fpeaks of his infect 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 prifmatic 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 refpect with the fpecimen you re- 
ceived from Mr. Markwick : :befides, I found another r blaek’ one, 
which appeared to me to be its female. — 
I fhall now proceed to give you fome further account of he's in- 
fects which prey upon Ti age Tritii. I have reafon to ae as T

Q). Le. mate. de cette petite efpéce eft allongé comme les précédens, avec le ventre 
mince et en filet. Sa couleur eft partout d'un noir matte. Ses antennes forment de 
beaux plumets. Ses ailes font d'un blanc laiteux, qui fe fait d'autant ge e A 
que fon corps eft fort noir. TG 
(q) La femelle eft très différente, & il faut iri avoir vů diongits eut pour n'en . 
pas faire une autre efpéce. Elle eft courte, groffe; de couleur jaune, avec les yeux noirs..
