greatly protect them, as men, animals, and birds at a superficial glance would take 

 these pupje to be only withered flowers o£ 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. Soc. Bengal, 1895, 499.) 



Wet and Dry i'oum only known. — As a result of our study of the various 

 species of this genus, we find that the typical, or dominant, species — Hecahe, is 

 represented by two forms only, namely, those of the Wet and Dry form. These two 

 forms being, jpresumably, each seasonally produced only in alternating climatic areas, or 

 both forms occurring together in the continuously-drier, or arid ai'eas. 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 aHke, in successive broods 

 only during the period of the annual local-equivalent of the Wet and Dry season, or, 

 ftoi/i /orms appear together throughout the annual cycle of its existence, cannot at 

 present be determined. 



The following is a table showing some interesting facts on the above point, the 

 dates of capture being taken from authentic labels of the captors : —
