The 3P OR SESE SA oC EE 
INDEED Names are arbitrary, and if remembered, and the Intent of them well un- 
derftood, may, whatever they are, ferve the Purpofe of giving them: But here, as in every 
Thing elfe, a Propriety 1s to be aimed at, and the Names groen ought to denote fome diftin- 
guifving Particularity, and that the moft obvious, in the Suljett on which they are beftowed, fo 
as to make the Name, if poffible, defcriptive of the Thmg: Which Rule has been followed as 
fiviclly as might be in naming the Moths and Butterflies contained in this Work: that is to fay, 
the Shape, the Colour, the Marking, the Food, or the Place where found is what they are 
named from. But in doing this, where the Author found them named to bis Hands in this 
defcriptive Manner, be has gladly retained the Name they had already, and only prefumes to 
bejtow Names bimjelf on fuch as either had none at all, or which he thought not fufficiently 
denotative of the particular Flies imtended to be known by them, 
— THE Divifion of the Work into Books and Chapters may need fome Explanation, fince 
under fome of the Divifions very few, or even but one Jingle Fly is placed; the Reafim whereof 
is, that the Plan bere laid down is intended for the Arranging of all the Moths and Butterflies, 
whofe Progreffion is known at prefent, or foall bereafier be aifcovered in England; of which, 
as the Flies here given are but a {mall Part, this muft be confidered but as an Out-line to 
be filled up occafionally. 
IT is hoped the Directions here geven how to collect the Caterpillars or Chryfalides, how to 
feed and take Care of them, how to preferve the Flics when bred, and where and at what Times 
they may be found moft eafily, will prove both acceptable and ufeful to every curious Collector 3 
and as the Author thinks himfelf under great Obligations to the Subfcribers to, and Encoura- 
gers of this Undertaking, a Lift of their Names is added as a Memorial of his Gratitude. 
THESE Things being premifed, we come now to give a fort Sketch of the Natural Hiltory 
of the Englifh Moths and Butterflies sm general.
