NORTH AMERICAN LEPIDOl'TERA. 199 



North Carolina, New Mexico, Colorado, Canada. Also common 

 in Europe. The New Mexico specimens were taken in August and 

 September. 



Zeller describing this insect speaks of it as an importation from 

 America, though unable to give ])roof of the statement. Mr. Rag. 

 onot catalogues it as an American insect, having it from North 

 Carolina. In "Insect Life," April, 1889, vol. i, p. 315, Riley, how- 

 ever, says : " I think it can be safely said this s[)ecies {E. kxiehniella Z. ) 

 does not occur in the United States." 



Whether the species originated in An)erica I am unable to say. 

 I have specimens of this insect from Colorado and New Mexico, 

 which I believe ai'e indigenous. Tlrey agree entirely with specimens 

 from Europe and from Canada, where the insect began depredations 

 last year. Mr. Ragonot describes E. fuscofasciella from specimens 

 from Texas and Missouri. I have specimens from New Mexico, 

 which connect the two, so fuscojmciella may be a variety only. 



I have just received, by the kindness of Prof. Fernald, a bulletin 

 on " The Flour Moth," issued by the Provincial Board of Health 

 of Ontario, dated Oct. 19, 1889. In this, information is given of 

 the appearance of Ephestla kuehniella in a flour-mill of Ontario. It 

 has multiplied with very great rapidity, and threatens to become a 

 very great pest. I do not know that it has given trouble in Cali- 

 fornia, if indeed it exists there. It has, however, developed very 

 rapidly in Europe, becoming a very great evil. The " Ontario Bul- 

 letin" speaks of it as having been probably introduced from Europe, 

 though there is no reason why it should not have come from the 

 Pacific coast. 



Miss Omerod, of England, quoted in the " Ontario Bulletin," says 

 the caterpillars are about five-eighths of an inch in length, pale red 

 to white in color; the head is yellowish brown, darker in front; 

 mandibles dark brown; thoracic shield dark brown, with a faint 

 pale central line dividing it on dorsum, and a small brown spot on 

 each side of it on the same segment ; a subdorsal and a lateral row 

 of piliferous spots on each side, one spot on each segment in each 

 line. Anal shield oval-triangular, brownish. The caterpillar is 

 covered with a few widely scattered hairs. It lives in flour and meal, 

 making a silken gallery, in which it lives, webbing togetlter masses 

 of the flour. It pupates in a cocoon in this gallery, and emerges as 

 a moth in aliout three weeks. It nuiy be found ahnost any time
