106 | Rev. Mrs Ka RBX'S: Continualion of the 
the way to no difcovery of this kind, may it be faid that we have 
been idly bufy and unprofitably laborious, when we have fucceeded 
in developing fome of the moft curious myfteries of nature, and in 
laying open the hiftory of fome of thofe fecondary. caufes, which, 
guided by the hand of Providence, produce fcarcity or plenty: as the 
one or the other preponderate ? E 
- As I made my defcription of Tipula Tritici lat year from a fi ngle 
Ípecimen,. and. that, produced before i its time, it will hardly be decried 
tautology. if I draw out a new. one ; 5 more efpecially. as an error with 
refpe&t. to the colour of. its wings. much calculated to miflead an 
_ examiner, has crept into it. In my. MS. I find it “ alis albidis? but 
 Yfee it is printed : e alis , byalinis,” an ‘expreffion ) which completely mif- 
reprefents their colour. As two new fpecies of Ichneumon. are to be 
defcribed, it may alfo not be amifs to work over again the defcrip- 
tion or. dcbneumon, t rd with. a view jo. aom: 
T. rufo-fulva; oculis nigris; alis lacteo-iricoloribus margine pilofis. 
Femina (c). 123 
Tota rufo-fulva; thorax intenfiüs, pedes autem dilutiüs. Antenne 
"eorpore nd odgiorty duodecim-articulatz: articulis pedicellatis 
fhort-fightednefs, and « our - ignorance "of the acer parts of the gteat plan. of Providence. 
We fee and feel the mifchief occafioned by fuch creatures, but are not aware of the good 
ends anfwered by them, which probably very much exceed it. I have heard of farmers, 
who, after having taken great pains to deftroy the rooks from their farms, upon being 
fuccefsful, have fuffered infinitely more in their crops, from the great increafe of the 
larva of infects, before kept. under by thefe birds, than they ever did from the rooke. 
themfelves. The fame might be the cafe, could we annihilate the Tipula of the wheat ; 
for every link of the great chain of creation is fo clofely connected on each fide with 
others, and all parts fo combine into one whole, that it feems not eafy to calculate the 
_confequences that would arife from the entire removal of the, moft infignificant, if any 
can be seemed fuch, from the fyftem. ees Tab. iv. fig. Is- :
