jpecies, already mentioned as occurring in corn, was likewise 
n the strawberry this year, a leaf roller collected July 20 
on the 25tli, and emerging at a date unknown as the imago

Pavia aterrima, Oliv.

9th May this species was seen near Normal in copula , on 
y leaves, upon which the beetles were feeding, during May 
\ first part of June. 
)onse to an urgent letter of inquiry from Mr. Wm. Jackson, 
3 y, respecting the complete destruction by insects of some 
p strawberries in his neighborhood, I sent an assistant thither 
dr 25, with directions to ascertain the cause of the injury. 
Ids were visited at Upper Alton and Godfrey. In two of 
|> greater part of the leaves had been riddled and killed, only 
the center of each stool remaining green. The third was so 
from the same cause, that it had been recently plowed up 
yner. 
S search of these fields revealed no insect capable of doing 
hief except Pavia atervima, and this was so abundant as to 
l ground for the suspicion that it was the author of the

jield, the young leaves occasionally put forth had been 
nawed in the manner characteristic of the work of this

llections of this season and the results of breeding cage 
its all serve to confirm our former account of the life his- 
. nebidosus and yield the further interesting fact of the 
he, beside, of another very similar species, which feeds only 
yening primrose (Oenothera), and whose life history is very 
from that of the first.

in Southern Illinois from April 6 to 9. Two larvae obtained 
seemingly only half grown, yielded small adults June 18.
