392 INSECTS INJURIOUS TO VEGETATION. 



that have appeared in some of our agricultural journals, I am 

 led to think that this corn-moth, or an insect much like it in 

 its habits, prevails in all parts of the country, and that it has 

 generally been mistaken for the grain-weevil. Many years ago 

 I remember to have seen oats and shelled corn (maize) affected 

 in the way above described; and Dr. Asa Fitch has favored 

 me with a grain-moth, obtained in a flour-mill at East Green- 

 wich, New York, which agreed with the descriptions and 

 figures of the European Tinea granella. In some remarks 

 upon this insect in the Albany " Cultivator," for January, 1847, 

 he states that the American insect was observed to make its 

 cocoon within the webs among the grain, instead of retiring 

 therefrom when about to undergo its transformations. The 

 habits of the European grain-moth are probably sometimes 

 varied ; for, although most wTiters on its history agree in saying 

 that the insect leaves the grain and conceals itself in crevices 

 of the granary when preparing to make its cocoon, Olivier* 

 expressly states that it undergoes its transformation in its web 

 among the grain. 



There is another grain-moth, which, at various times, has 

 been found to be more destructive in granaries, in some pro- 

 vinces of France, than the preceding kind. It is the Angoumois 

 moth, or Ariacampsis [Butalis) cerealella, an insect evidently 

 belonging to the family of Yponomeutad^, or Yponomeutians. 

 The winged moths of this gi'oup 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 Entomology,"! by the Rev. Mr. Kirby 

 and Mr. Spence, that the insect under consideration is not 

 yet named. This, however, is a mistake ; for it was named 

 Alucita cerealella, by 01ivier,| as long ago as the year 1789. 

 Olivier's name for it appears also to have been overlooked
