equal size; on segments 5 to 9 inclusive, tubercle iii is slightly 

 above, and anterior to, the spiracle; iv is behind and almost in a 

 line with the lower end of spiracle; v is below% and slightly anterior 

 to, spiracle; same distance therefrom as iii. On segments 10 to 12, 

 however, tubercle v is immediately below the anterior side of 

 spiracle. On segment 12, tubercle iv is also below the spiracle. 

 Spiracles black, oval in shape. Stigmatal band whitish, blackish 

 border beneath irregular and not so conspicuous as in previous 

 stage. Thoracic feet and prolegs as in Stage IV. 



(^n June 4 some of the larvse were mature and entered the 

 earth for pupation. On this date they were 39 mm. in length and 

 4.5 mm. in width. 



Pupa (fig. 4, pi. XIV). — Length 14-16 mm., 4.5-5 mm. in width 

 at widest part; shining, reddish brown, thorax and wing-cases 

 wrinkled. Abdomen moderately punctured, abdominal fold dense- 

 ly, very minutely, punctured in concentric rows. Spiracles black. 

 Cremaster dark brown, bearing two divergent, almost straight, stiff, 

 spines; close to the base of the cremaster there are also two, short, 

 thick, blunt, spiniform protuberances, one on either side. 



Most of the moths emerged (in a cool cellar) in the end of 

 April and early in May, 1904. A breeding jar containing some of 

 the pupiie was kept in the laboratory and in this moths emerged in 

 January. Males and females were kept alive and in one instance, 

 on January 9, a male and female mated and remained in coitu for 

 80 hours. In the wooden box in which the moths w^ere confined 

 there was an open crack in the bottom, and when the box was 

 moved on January 11 it was noticed that the female had inserted 



her long ovipositor through 

 the crack and laid eggs on the 

 imderside of the bottom close 

 to the crack, the bottom of 

 the box being slightly elevated 

 above the lower edge of the 

 sides. The ovipositor of the 

 moth (fig. 16) measured in
