Calocampa exoleta. Large Stvord-grass Moth. This, 

 which is the most common species of the genus, measures 

 about two inches ; the prevailing colour is ochreous, in some 

 parts inclining to reddish-brown ; the upper wings marked 

 with dusky brown, each having two ear-shaped spots near 

 the middle ; the hinder wings are grey, with a dark spot 

 towards the base; the thorax is dark brown; the body 

 reddish-ochre, with bands of dark brown. The caterpillar 

 is very beautiful, and of a rich green, the back adorned with 

 two rows of white spots ; below this, is a yellow line, then 

 a series of small round spots, and a red line above the legs ; 

 it is a very general feeder, but seems to prefer lettuce and 

 asparagus. The moth is by no means common.
