Another and much commoner insect, the Indian-meal moth (Plodia 
interpunctella) depreciates upon grain in much the same manner as T. 
granella, and it is more than probable that a very considerable propor- 
tion of alleged cases of damage by granella are in reality due to the 
ravages of Plodia. Few collectors of insects have the patience and skill 
to properly mount specimens of these microlepidoptera, hence it might 
happen that even unspread moths of Plodia would be mistaken for 
Tinea granella. The larva and pupae, though only superficially alike, 
cannot be distinguished except by rather close study or by comparison. 
EARLY ACCOUNTS OF HARRIS AND PITCH. 
The earliest account that can be found in American literature appears 
in Harris's Report on the Insects of Massachusetts Injurious to Vege- 
tation, published in 1811. This is a compilation from European works, 
as appears from the concluding paragraph, in which this writer says: 
"The foregoing account will probably enable the readers of this essay 
to determine whether these destructive insects are found in our own 
country. From various statements, deficient, however, in exactness, 
that have appeared in some of our agricultural journals, I am led to 
think that this corn-moth, or an insect exactly like it in its habits, pre- 
vails in all parts of the country, and that it has generally been mistaken 
for the grain- weevil, which it far surpasses in its devastations. Many 
years ago I remember to have seen oats and shelled corn (maize) 
affected in the way above described, and have observed seed-corn 
hanging in the ears, to have been attacked by insects of this kind, the 
empty chrysalids of which remained sticking between the kernels; but, 
for some time past, no opportunity for further investigation has offered 
itself.*' 
In the account of the Angoumois grain moth which immediately fol- 
lows, and which is likewise compiled, it is perfectly plain that Harris 
was not at the time of this writing familiar with the work of either 
species. 
Fitch gave some notes on Tinea granella in the Cultivator of January, 
1847, which the writer has not been able to obtain, but Harris, in the 
Flint edition of Insects Injurious to Vegetation, remarks: "Dr. Asa 
Fitch has favored me with a grain-moth, obtained in a flour-mill at 
East Greenwich, "N". Y., which agreed with the descriptions and fig- 
ures of the European Tinea granella." If this last was truly granella, 
and this can be neither affirmed nor denied, it is somewhat singular 
that Fitch does not mention this species in his subsequent reports on 
"insects affecting grain crops." 
glover's grain moth. 
Passing by the writings of Gaylord, Brinkle, and Emmons, in which 
mention is made of T. granella as unreliable, for the reason that these 
writings evince no evidence of original observation, we come to the
