 Moth. The primary wings dark brown, marked with several 

 waved stripes of deep black and red, the latter colour mark- 

 ing the nervures on the hinder margin ; near the centre of the 

 wings there is a round whitish spot ; the secondary wings are 

 deep yellow, with two dark bands ; the head and thorax are 

 similar in colour to the upper wings, the latter having a large 

 spot somewhat resembhng a human skull. The caterpillar 

 is sometimes five inches long, of a fine yellow, with seven 

 oblique bands of green on each side, and a series of blue 

 spots on the back, which is also marked with black ; it 

 feeds principally on the potato, and is much more common 

 than the perfect insect, as many of them die before complet- 

 ing their transformation. These fine insects are found in 

 various localities both in England and Scotland, and appear 

 to have been very abundant two years since.
