 Maple-worm, and is sometimes a serious pest on soft-maple 

 shade-trees. It measures when full grown about one and 

 one half inches. It is pale yellowish green, striped above 

 with eight very light, yellowish-green lines, alternating with 

 seven of a darker green, inclining to black. There are two 

 prominent horns on the second thoracic segment, and two 

 rows of spines on each side of the body, one above and one 

 below the spiracles. And on the eighth and ninth abdomi- 

 nal segments there are four prominent dorsal spines. The 

 species is one- or two-brooded, and winters in the pupa 

 state.
