THE ANGOUMOIS GRAIN-MOTH. 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) cerealella, an 

 insect evidently belonging to the family of YPONOMEUTAD^E, 

 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 Alucita cerealella, by 

 Olivier,! 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 (EcopJiora grandla.\ 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 Laverna, 

 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
