noticed June 12-13th. 
The pupa (Fig. 2-2c), 2, natural size, bulges out considerably on 
the 4th and 5th abdominal segments. There are only three pairs 
of spiracles, z. e., on the 2d, 3d and 4th abdominal segments. One 
of these spiracles (highly magnified) is represented at 2c ; their 
relations to the body at 24, 
The moth was not directly raised from the pupa, but the for- 
mer were so thick that I have little doubt but that the Hydro- 
campe captured at the same spot a few days after the larvæ were 
found, were the imagines of the larvæ under consideration. Seek- 
ing for them the next year, none were to be foufd, though very 
prolonged search was not made for them for want of time. 
The moth found so abundantly, and seen on the following sum- 
mer at the same date as above recorded, was Hydrocampa formo- 
salis of Clemens (Fig. 3. The drawing is a very poor one). i

Cataclysta and five of Paraponyx, and it is to be ho tha
