LEPIDOPTERA. 397 



continued reproduction of the insect, in stored grain, at short 

 intervals, throughout the warm season, or from the latter part 

 of June till further increase is checked by cold weather. Mr. 

 Rutfin thinks that but very few eggs are deposited on corn in 

 the field, that these do not ordinarily hatch till the following 

 summer, and that then they are sufficient to stock the whole 

 crop of stored grain with their progeny. Mr. Samuel Judah, 

 of Vincennes, Indiana, in a short and very sensible article, 

 published in "The Indiana Farmer and Gardener" for Octo- 

 ber 4, 1845, seems to have come to nearly the same conclu- 

 sions. Mr. Richard Owen, of New Harmony, Indiana, has 

 given a very good history of this insect, accompanied with 

 wood-cuts, in " The Cultivator," for July and November, 1846. 

 To this I may have occasion again to refer, as also to two 

 other articles, on the same subject, by Edward Ruffin, Esq., in 

 the sixth volume of " The American Agriculturist," pages 52 

 and 93, published in February and March, 1847. 



In the summer of 1840, Mr. E. C. Herrick, of New Haven, 

 Connecticut, sent to me a few grains of wheat, that had been 

 eaten by moth-worms precisely in the same way as grain is 

 attacked by the Angoumois insect; and a gentleman, to whom 

 this moth-eaten wheat was shown, informed me that he had 

 seen grain thus affected in Maine. Unfortunately, the insects 

 contained in this wheat were dead when receired, having 

 perished in the chrysalis state. Had they lived to finish their 

 transformations, they would have afiforded me an opportunity 

 of ascertaining their suspected identity with the fly-weevil of 

 Virginia, and the Angoumois moth of France. All my at- 

 tempts to obtain specimens of the fly-weevil from the South 

 and West were unsuccessful, till the tenth of November, 1845, 

 when I had the pleasure of receiving a parcel of damaged 

 wheat and a bottle full of the moths from Richmond, Virginia, 

 through the kindness of Mr. John Dunlop Osborne, then a 

 student in the Law School of Harvard College. Living speci- 

 mens, and the insects in the worm or larva state, were still 

 wanting. These were most unexpectedly obtained nearer 

 home. The late Samuel M. Burnside, Esq., of Worcester, 

 told me, in the summer of 1844, that he had a quantity of
