826 General Notes. [August, 



cocoon within the case from June 4-ioth; the moths being 

 noticed June 1 2-1 3th. 



The pupa (Fig. 2-2<r), 2, natural size, bulges out considerably on 

 the 4th and 5th abdominal segments. There are only three pairs 

 of spiracles, i. 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 2b. 



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- 

 campae captured at the same spot a few days after the larvae were 

 found, were the imagines of the larvae under consideration. Seek- 

 ing for them the next year, none were to be found, 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 forvio- 

 salis of Clemens (Fig. 3. The drawing is a very poor one). 



We have in this country four species of Hydrocampa, five of 

 Cataclysta and five of Paraponyx, and it is to be hoped that 

 many years will not elapse before the larvae, at least those of 

 the latter-named genus, will be discovered. It is hoped that this 

 note will serve to draw attention to these very curious insects. —
