a similar oue along each side. On the first six segments following 

 the head there is a bluish tubercle armed with several black spines 

 on each side of the dorsal line, and on the remaining segments, these 

 tubercles are dark crimson red. On the middle of the 10th and 11th 

 segments there is a smaller red tubercle notched at the top. The 

 whole surface of the body is somewhat hairy, but along each side the 

 hairs are long and form quite dense clusters. 



Fig. 4. 



The pupa, fig. 4, is from three-fourths of an inch to an inch in 

 length, and varies in color from chocolate to reddish brown. On 

 each side, at the base of the wing-covers is a dark reddish brown, 

 oval, velvety spot. The wing-cases are quite broad and reach to the 

 posterior third of the fifth segment. The antennae cases are strongly 

 curved, and are quite wide in the middle. There are a few yellowish 

 brown hairs on the face and head, also on the first five segments, 

 arranged in broken circles or clusters, which are in longitudinal and 

 transverse rows. The cremaster or spine at the posterior end is 

 flattened, rounded at the outer end, grooved longitudinally, and has 

 twelve or more minute hooks at the end. 



The moths emerge from the pupae from the first to the middle of 

 July.
