gana and other shrubs in the arboretum, Central Experi- 

 mental Farm. In 1905, eggs were secured from a captured 

 female. They were laid on July 1st and hatched on July 

 7th. The larvae in Stage I were pale greenish, skin smooth 

 and shiny, the segments rather deeply divided. Tubercles 

 small, black, each bearing a blackish bristle. Head semi- 

 translucent with a brownish tinge; mouth parts yellowish- 

 brown; ocelli black. Thoracic feet concolorous with head; 

 prolegs concolorous with body. Moulted 14 July. My note 

 on Stage II reads: Length 6.5 mm., pale greenish cylindrical 

 larvae, with black tubercles, each with a rather long stiff 

 black bristle — much the same as Stage I. Head paler 

 than body. No further notes were taken owing to pressure 

 of other work. The mature larva has been described 

 fully by Chittenden.* 



On July 8, 1901, specimens of the larvae of this species 

 were found at Ottawa feeding on common plantain, 

 Plantago major. Pupation took place on July 12, and the 

 moths appeared about a fortnight later. In 1912, I found 

 a larva on cabbage, which changed to pupa on July 30, the 

 moth emerging on Aug. 19. Mr. C. H. Young has found 

 the larvae feeding on grass and clover.

In addition to this specimen Mr. Young collected a 

 female moth from which he secured eggs. The young larvae 

 were fed on dandelion and by autumn had grown to rather 

 more than half an inch in length. They stopped feeding 

 and acted as if they wanted to hibernate. They died, 

 however, before winter.

On May 28, 1901, I found the larvae fairly aeundant, 

 on a hillside near the Rideau Canal, feeding on Solidago 

 canadensis. The larvae were nearly full grown and it was 

 extremely difficult to see them on the food plant. They were 

 nearly all collected by "beating." The following descrip-
