>wing this, on page 363, in the number for December, 1870, 
a long article upon this insect, which is there called the “fall 
jyorm,” and described and discussed as Prodenia autumnalis n. s. 
otli and larva are figured and very fully described, a brief 
tion being also given of the pupa. Two varieties of the 
are distinguished and described as fulvosa and obscura; the 
mce of the worm in destructive numbers during that season 
ly parts of Kansas, Illinois and Missouri is noted; compari- 
its characters and habits with those of the common army 
s made at length, the probable number of its broods and other 
in its life history are discussed, and an account is given of its 
of oviposition, and a description of the egg. In Riley’s second 
page 41, this species is referred to as Laphygma frugiperda of 
and Abbott, but evidently not identified by the writer with 
heat cutworm” of his previous report.

autumnalis. This article is substantially the same as that.
