sand of a small stream in the McLean swamp. Unfortunately the

alcohol evaporated from the bottle of preserved specimens, leav- 
ing the larve worthless, but the cases did not deteriorate. 
Adults of the genus are not uncommon near Cayuga Lake, 
from which they probably emerge. 
Hasits.—The larve observed were neatly nestled in the sand 
of the stream’s bottom, where the wings of their cases blended so 
perfectly with the surrounding sand that they were most difficult 
to detect. Probably the genus would be found not uncommon if 
the cases could be more easily seen. 
Tue Larv#.—Molanna is the only American genus of the 
subfamily Molanninz, which can readily be distinguished by the 
spur of the middle and front tibia. In Molannine the spur arises 
on a distinct prominence, while in the subfamily Berzinz the prom- 
inence is entirely absent. Figure 183 represents the front leg 
of Molanna uniophila, furnished by Mr. Vorhies.
