Of the 318 specimens, 154 are only fragments of the others, but 
few in tolerable condition. 
The portions of Harris Collection belonging to the groups men- 
tioned in this Report, contain even now nearly one-fifth of the num- 
ber of species described in my Synopsis for the whole United States, 
and nearly the number given at that time for New England and New 
York. From this fact alone, the collection is very important, and 
especially so as the exact date and locality is given for most of the 
specimens. ‘The collection contains a considerable number of species, 
formerly only known from Canada, and even from the northern parts 
of it. Most of these are from the White Mountains and Maine, but 
some even from Massachusetts, where nobody would have believed 
their existence. Besides there are a number of types of species de- 
scribed by Say, nowhere to be found, since Say’s own collection was 
destroyed. It is remarkable that some of the species in Harris’ Col- 
lection seem to be of the greatest rarity, only represented by iso- 
lated specimens in other collections; some are even now uniques. 
The collection of a so eminent an entomologist as Dr. Harris, is, by 
itself, a treasure, and not only a national treasure, but one in whose 
preservation the whole scientific world is interested. The coming 
generation will not be able to understand why sufficient care was 
not taken from the first to preserve a collection so invaluable as com- 
pletely as possible. I am happy to be assured, however, that further 
destruction is not: to be feared. 
Most of Harris’ catalogue names are published in his list of Neur- 
optera, in Hitchcock’s Report, second edition, 1835, p. 580 — 582.
