The objection made of the want of _names_ to the insects contained in my first volume, the reader will here find removed; and _trivial_ as well as _generical_ ones, given to every insect in the whole work: and likewise a few errors of the press corrected, that have almost imperceptibly got in. I was, indeed, truly sensible of the defect and incompleteness of that volume, occasioned by the above circumstance, and would gladly have named every insect then delineated; but the different opinions subsisting at that time among entomologists, some preferring one author and some another, made me exceeding cautious of entering on that business: and I rather chose to defer it to the present opportunity, than give occasion for any reflections against me, for my attachment to an author, whose method I should certainly have pursued, and whose works have deservedly entitled him to the appellation of _father_ of natural history. I mean the excellent Linneus, whose system seems now to be generally approved and followed; and I must here mention, the opportunity that the present work affords of giving an explanation of the terms, &c. in his work, I should certainly have availed myself of, for the benefit of the young beginner; but as my friend, Mr. Curtis, has published a good translation of the "Fundamenta Entomologiæ" of that author, wherein the young student, as well as the adept, who are not versed in the Latin tongue, may receive great improvement; I must refer them to that work for the properly understanding the plan and design of that great author. The reader will observe, that in giving _trivial_ names I have strictly followed the method of Linneus. The Butterflies entitled to be ranked among the Equites, are named after some great personage found among the Greeks and Trojans; as in Plate iii. Fig. 1. where I have named the insect Antenor, from a Trojan prince; and Plate ix. Fig. 1, 2. Menestheus from a Grecian one; one belonging to the Eq. Trojanes, the other to Eq. Achivi. I have likewise followed his rule in naming the insects belonging to other classes; and given such as I concluded to be the most easily retained in the memory. To this end also I have used the Latin language in preference to the English, for the great liberty it allows {vi}of compounding and decompounding words and names; a circumstance of the greatest consequence in a business of this sort.
