ON THE SO-CALLED INTRODUCTION OF HELIOTHIS 
DIPSACEA L. INTO THE UNITED STATES 
By Foster H. Benjamin

Throughout the earlier literature there are scattered ref- 
erences of the occurrence within North America of this Pa- 
learctic Heliothid. All of these seem to apply to the in- 
digenous Heliothis phloxiphagus Grote and the name was 
dropped from the more recent lists. 
A paper by Mr. Fred H. Walker was published in 1928 
(Psyche, XXXV, 29-30), definitely stating that the Euro- 
pean species actually did occur in Massachusetts. 
Through the kindness of Mr. C. W. Johnson one of the 
Walker specimens was submitted for examination. Both 
upon superficial characters and upon male genitalia it is the 
ordinary American phloxiphagus.
