greatly protect them, as men, animals, and birds at a superficial glance would take 
these pupaa to be only withered flowers of the Cassia , or ripe seeds of the grass. 
After six days in the pupa state the imago emerges. Though so weak and slow in 
flight, they are very clever in avoiding being caught by the net.” (Dr. L. Martin, 
J. As. See. Bengal, 1895, 499.) 
Wet and Dry dorm only known. —As a result of our study of the various 
species of this genus, we find that the typical, or dominant, species— llecahe , is 
represented by two forms only , namely, those of the Wet and Dry form. These two 
forms being, presumably, each seasonally produced only in alternating climatic areas, or 
both forms occurring together in the continuously-drier, or arid areas. The pattern 
and shape of the band on upperside of both wings, in each form, from all our cited 
areas, being identically the same—this, doubtless, is due to the climatic conditions, 
in each of the several areas, being the same during the periods of its existence. 
Whether these two forms of Hecabe are each produced alike, in successive broods 
only during the period of the annual local-equivalent of the Wei and Dry season, or, 
both forms appear together throughout the annual cycle of its existence, cannot at 
present be determined.
