THE ANGOUMOIS GRAIN-MOTII. 
499 
There is another grain-moth, which, at various times, 
has been found to be more destructive in granaries, in some 
provinces of France, than the preceding kind. It is the 
Angoumois moth, or Anacampsis ( Butalis ) cei-ealella, an 
insect evidently belonging to the family of Ypon omeuta d je , 
or Yponomeutians. The winged moths of this group have 
only two visible feelers, and these are generally long, slender, 
and curved over their heads. Their narrow wings most 
often overlap each other, and cover their backs horizontally 
when shut. It is stated in the “Introduction to Entomol- 
ogy,”* by the Rev Mr. Kirby and Mr. Spence, that the 
insect under consideration is not yet named. This, how- 
ever, is a mistake; for it was named Alacita cei-ealella, by 
Olivier, f as long ago as the year 1789. Olivier’s name 
for it appears also to have been overlooked by Latreille, 
who has given it that of (Ecopliora granella.% Moreover, 
the writers of the “Introduction” have extracted from the 
works of Reaumur § an account of the habits of this insect, 
which they call Tinea Hordei and Ypsolophus granellus , || 
without seeming to be aware that it is the same as the 
Angoumois moth. In the first edition of this treatise, I 
stated that “ the Angoumois grain-moth probably belongs 
to the modern genus Anacampsis , a word derived from the 
Greek, and signifying recurved, in allusion to the direction 
of the feelers of the moths.” To this genus, as understood 
by most English entomologists, it certainly does belong; 
but Mr. Curtis is disposed to place it in his genus Lavcrna, 
including certain species which he has separated from Ana- 
campsis. The French naturalist Duponchel, who has de- 
scribed and figured it in the fourth volume of the Sup- 
plement to his “ Histoire Naturelle des Ldpidopteres de
