pocapsa pomonella Linnaeus) August 30, 1921 (E. R. Van Leeu- 

 wen) ; it has four dorsocentrals, and the abdomen is a little less 

 golden. 



We have seen only males of Townsend's angustifrons ; they are 

 from Brazil and Bolivia, and have the black posterior bands of 

 the second and third abdominal segments wider, but otherwise are 

 hardly distinguishable. Females from South America would prob- 

 ably settle the question. The South American species is known to 

 vary in the number of dorsocentrals.
