 (Patgram, 20-viii-07) and a Papilio (Sadiya, Upper Assam, 25- 

 viii-09) : Leonotis nepetaefolia those of a bee of the genus

Strobilanthes Mastersii, T. Anders., is certainly well 

 suited for the visits of the larger bees; but Apis dorsata only 

 has been seen on it This insect visited persistently at Kobo, 

 Upper Assam (30-xi-ll and 4-xii-ll). 



Irregular flowers suited for Apis and other small bees. 



Capparis tener, Dalz., is strikingly adapted for the visits 

 of the more intelligent insects, such as the bees, on account of 

 the neat way in which its honey is hidden in a little lenticular 

 cavity made by the apposition of nectaries on the bases of the 

 upper petals. The accompanying figure shows the appearance
