90 BULLETIN 132, UNITED STATES NATIONAL MUSEUM 



I have examined the types of Kearfott's two species carefully and 

 can see no real difference between them, genitalic or otherwise, except 

 size. P. liriodendrana is somewhat larger ; but in reared series from 

 Liriodendron we have specimens quite as small as any from Magnolia. 

 The larvae feed commonly upon the leaves, rarely in the seed pods. 



Male genitalia with long tuft from base of sacculus of harpe; 

 arch of neck wide ; spine cluster Spc ^ absent ; aedoeagus smooth. 



Genitalia figured from reared specimens in National Collection 

 from Falls Church, Virginia (Hopk. U. S. no. 11149, Heinrich, June 

 28, 1913, male) and Montclair, New Jersey ("K-672, iss. VIII- 

 10,"' Kearfott, female). 



Distribution. — New Jersey, Pennsylvania, District of Columbia, 

 North Carolina. 



Alar expanse. — 10-14 mm. 



Types. — In American Museum. 



Type locality. — District of Columbia {liriodendrana and mag- 

 noliana). 



Food plants. — Liriodendron tulipifera^ Magnolia virginiana.

The common American grape berry moth of economic literature. 

 For a number of years, until Kearfott pointed out its distinctness, it 

 liad been confused with the European hoPranu. The two species 

 dif er radically ii both genitalia (compare figs. 358, 362) and vena- 

 tion; hotra?ia having vein 10 of fore wing rather close to 9 at base, 

 ^\ hile viteana has it well separated, if anything nearer 11. 



Male genitalia with weak spining on base of sacculus of harpe; 

 !<pine clusters Spc'^ and Spc~ strongly developed, arch between them 

 narrow; a third cluster consisting of two heavy, flat, sword-like, 

 closely grouped spines arising from harpe at base of cucullus; 

 aedoeagus with small projecting tooth on upper edge near apex. 



Male and female genitalia figured from reared specimens in Na- 

 tional Collection from Northeast Pennsylvania (" X-16," Cushman).
