them crawling about over sacks containing roots ot aandeliou — moths, 

 in fact, being found in the bags ; we found numerous larvae infesting 

 wheat in the Atlanta Exposition building in 1884; large numbers of 

 larviB were also found in a jar containing Chickasaw plums at the 

 same exposition; larvae were received from Ripley, Miss., on two occa 

 sions in 1885, some of which were said to have been found feeding on 

 sugar in barrels; one specimen was bred from dry Opuntia from Texas; 

 larvae were received from Detroit, found among old books ; larvse 

 of all sizes were found infesting Pecan nuts in St, Louis, in September, 

 18(2; moths were bred by Dr. A. W. Hofmeister in Iowa from Cinna- 

 mon bark ; moths were bred from English walnuts in St. Louis in 1876, 

 and the species in all states was found 

 abundantly in a wheat warehouse in Alex- 

 andria, Va., in 1883. Moreover, in 1873, at 

 St. Louis, one of these moths was bred 

 from old woolen stuff in company with 

 Tineola biseUiella, but there is some doubt 

 connected with this case. 



We have figured the states of interpunc- 

 tella (Fig. 30) in comparison with those of 

 hulmieUa (Fig. 28), in order that both may 

 be readily recognized. The early states 

 are quite similar in appearance, but the 

 larvie may be distinguished by the follow- 

 ing characters : 



The larviB of Mlhniella are more slender and of a more uniform diam- 

 eter than those of the other species. The abdominal legs are longer, 

 cylindrical, with a circular fringe of booklets at the crown. In mter- 

 punctella the legs are short, conical, with the fringe of booklets at the 

 crown oval. All piliferous warts in Jciihniella, most of which are rather 

 minute, are still rather prominent, readily observed, and of a black or 

 brown color. Those most conspicuous are the lateral ones, in front of 

 the first spiracle; the subdorsal one, each side of the mesothorax, 

 almost completely encircled by a narrow black ring interrupted only at 

 its upper margin (Fig. 2Sd). In interpunctella all the warts, while pres- 

 ent, are concolorous with the rest of the body, and can be distin- 

 guished only with great difficulty. The surface of the body of Mlhniella 

 is almost perfectly smooth, while that of interpunctella is somewhat 

 granulate.
