very different from that of any of the other species (Fig. 44). Female 
apical segments as in Figure 43. 
We consider it| proper to assign a name to this very well-defined 
species though it may eventually prove to have been already described. 
A careful examination of the hypopygia of all the species in the genus 
is essential to a clearing up of the synonymy. 
Type, male, Bloomington, Ill., September 30, 1919, taken in a field 
of sweet corn which was destroyed by larvae of the fall army-worm 
(J. R. Malloch). Allotype and one female paratype without locality 
labels. 
Named in honor of Mr. D. J. Caffrey, who kindly supplied much 
of the material for the study of nubilalis. 
The immature stages and food plant of this species are unknown 
» to us at this time. 
For the identification of obumbratilis we are indebted to Dr. W. T. 
M. Forbes who, on a visit here some months ago, thus identified several 
specimens in our collection, some of which had been reared from corn- 
stalks in which the larvae had evidently passed the winter. This species 
was not included in the Twenty-third Report of the State Entomologist— 
“A Monograph of Insects Injurious to Indian Corn’’—as its habits were 
not known here until a year after that report appeared, the first Illinois 
specimen being reared in 1906. 
After this paper had been prepared for 
the press and before it was sent to the printer 
there appeared in the Journal of Agricultural 
Research a paper by Carl Heinrich on the 
European corn-borer in which the name Py- 
rausta ainsliei is given to the species here 
designated as obumbratilis. We have exam- 
ined the series of obumbratilis in the collec- 
tion of Dr. Wm. Barnes, which contains some 
specimens reared by Kearfott from Typha ric. 44. Pyrausta caffreii, 
(cattail-flag), and after comparing the geni- eT OS cd 
talia of one of the males of the reared series proboscis incomplete. 
with some of those in our collection we are ; 
convinced that they are identical with ainsliei Heinrich. The basal spine, 
which is not figured by Heinrich, is easily detached from the genitalia in 
dissection, and is really present in the species he figures but evidently 
was lost in dissecting the specimen.
