Hence, ainsliei falls as a synonym of obliteralis. I am indebted to 
Mr. Whalley of the British Museum and to Dr. Duckworth of the 
U.S. National Museum for comparison of the material and verifica- 
tion of the suspected synonymy. 
Ostrinia penitalis (Grote), new combination 
Botis penitalis Grote, 1876, Canadian Ent., vol. 8, p. 98. 
Pyrausta penitalis (Grote).—Fernald, 1903, in Dyar, U.S. Nat. Mus. Bull 52, p. 
391. 
Marion’s (1957) paper transferring nubilalis (Htibner), commonly 
referred to as the European corn borer, from the genus Pyrausta 
Schrank to Ostrinia Hiibner was restricted to species occurring in 
Europe. Because of that fact, treatment of its contemporary Amer- 
ican congeners, Pyrausta ainsliei and Pyrausta penitalis (Grote), was 
omitted. P. ainslier is placed in synonymy under obliteralis herein, 
but penitalis is not a Loxostege or Phlyctaenodes species and has never 
been assigned to either of them; in a strict sense it is not an essential 
part of this study. Due to its association with ainsliet and nubilalis, 
however, there is considerable economic literature involved. P. 
penitalis is also hereby assigned to Ostrinia for its correct placement 
and uniformity of nomenclature in references to obliteralis, ainsliei, 
and penitalis.

Mats (fig. 170).— Alar expanse 13 mm. Frons conical. Antenna 
ciliate, cilia longer than width of shaft. Midtibia not incrassate; 
hair-pencil absent. Upper surface of forewing ochreous, markings 
pinkish. Hindwing white, without markings. 
Genitalia like those of pustulalis but with uncus and vinculum 
narrower, gnathos stouter, and aedeagus longer and more slender. 
Frema.e.—Alar expanse 14mm. Similar to male in color and macu- 
lation. Genitalia like those of pustulalis but with anterior and 
posterior apophyses shorter and collarlike structure of ductus bursae 
more strongly sclerotized.
