Kearfott's types of saundersana are simply runted specimens of 

 tristrigana. We have a considerable series of the latter reared from 

 both Baptisia and Lupinus and among the lot are several specimens 

 agreeing in every detail with typical saundersana as well as specimens 

 intergrading in size between it and typical ti^trigana. There are 

 no structural differences. 



Hind wing with veins 3 and 4 connate. 



Genitalia figured from specimens in National Collection from El 

 Vista, Tex. (reared from seed pods of Baptisia May 15, 1919, Hein- 

 rich, male and female). Bursa of female without signa. 



Distribution. — Illinois, Kansas, Oklahoma, Alabama, Texas, 

 Florida, North Carolina, Pennsylvania, New Jersey, New York, 

 Massachusetts, Ontario. 



Alar expanse. — 10-16 mm. 



Types. — In Academy Natural Sciences {tristrigana) ; American 

 Museum {saundersana). 



Type localities. — Virginia {tristrigana) ; Toronto, Ontario, Can- 

 ada {saundersana). 



Food plants. — Baptisia., Lupinus (larvae in seed pods and stems). 



10. OFATULENA, new genus 



(Figs. 30, 119) 



Genotype. — Grapholitha? duodecemstriata Walsingham (North 

 America). 



Thorax smooth. 



Fore wing smooth; termen straight or very slightly concave; 12 

 veins ; 7 to termen ; 11 from cell at middle ; 10 rather well separated 

 from 9; upper internal vein of cell from between 10-11; 3, 4 and 

 5 parallel from beyond cell, not approximate at termen ; 2 from cell 

 at %, straight; no costal fold in male.
