entered and betakes itself to the dead and 
curled leaf. Here it is easily found by 
other insects, and, from the difficulty of 
obtaining specimens in this stage, I infer 
that a very large number are destroyed by 
their enemies. 
In examining the chrysalids which I had 
obtained, I noticed that two or three were 
much larger than the rest, and I suspected 
that, in collecting nibbled leaves from the 
buckeye, I had introduced the larvae of 
some different species. ‘This suspicion was 
chavged to certainty when the moths 
emerged. Beside the genuine imago of the 
buckeye stem-borer, with which, by this 
time, I was quite familiar, I had two or 
three specimens of double its size, with 
cinnamon-colored wings having the costal
