228 Mr. MarsuAm’s further Obfervations on the Wheat Infe. 
Tritici of Mr. Kirby, and perhaps may prove to be the different fex; or 
it is poflible that Mr. Kirby might have taken his infeé immediately 
on its quitting the pupa ftate, and before the wings were completely 
dry, fo that the obfolete clouds with which they are marked had 
not become vifible. The manner in which both thefe Gentlemen 
met with this fly leaves very little doubt in my mind of its being” 
the true parent of the larve we have defcribed; and this opinion 
is very much ftrengthened by the very great affinity there feems to 
be between our Tipula and the Tipula Funiperina of Linnzus, and 
Tipula Pini of the Baron De Geer, Tom. vi. p. 417. Tab, xxvi. fig. 
8—r9; it however differs in colour from the Latin defcriptions of 
thofe infeéts, although it agrees in the other particulars. But the 
long French defcription which De Geer gives of Tipula Pini, varies 
very little from that of our infeét; and the figure, being uncoloured, 
would pafs for it very well, as the antenna and wings feem exaétly 
to correfpond: even the account of the larva is nearly the fame, 
except that he remarks a thin green line paffling through the body — 
of his, which he conjectures to proceed from the food, viz. the leaves 
of the pine; if this be the fact, fuch a line would not be vifible in 
our larve, as they feed on the pollen of the wheat, which is nearly 
their own colour: another difference is, that the larve of Z, Pini 
form little refinous cafes to preferve themfelves during the Winter ; 
but both continue unchanged until Spring, as appears by Mr. 
Kirby’s opening one of the cafes, which he fuppofed contained 
the pupa, and finding the larva unchanged, from which I con- 
clude that we have not yet feen the pupa. The flies of ZT. Fu- 
niperina and T. Pini do not come forth until May, which time will 
exactly fuit our little animal for depofiting its eggs in readinefs for 
the bloffom of the wheat; and from the appearance of fome of the 
little cafes which I have by me, that are fo tranfparent as to admit of 
a perfect view of the larva, Iam of opinion that they are approach
