Only one species is known in this singular genus ; it flies at 
dusk among Sparganium, heavily and sluggishly. The larva, 
when young, mines the leaves, and afterwards bores down the 
stems of the Sparganiwm ; it is dirty greyish-white, remarkably 
elongated, with a peculiarly flattened tail; it changes to a pupa 
inside the stem of the plant.
