Aesehynomene indica, Linn., was seen to be visited by a 

 Terias butterfly at Calcutta (12-ix-09). 



Centranthera hispida, R. Br., has been seen to be visited 

 bv a butterflv of the genus Terias at Gauripur, Mymensingh 



(6-ix-06). 



Rungia repens, Nees, has flowers which persist for three

 Then the stigma occupies alone the place where the head of
