fully grown the larvae descend into the ground, where they trans¬ 
form to pupae a few inches below the surface. The perfect insect 
makes its appearance in October. It is light buff-yellow with orange 
spots, while the hind wings are nearly white. 
Petropliora diversilneata. 
Petrophora diversilneata is a very pretty moth, which often makes

to do much damage.

During August the pretty little moth, Hcematopis grataria , may 
be found in meadows, especially near streams, where it is sometimes

alighting after it has been flushed from the grass. Its colors are 
yellowish-red crossed by bands of pink. The larva is said to feed on 
chickweed.
