1916.] The Pollination of Flowers in India. 249 



Xylocopa visits the flowers of Luffa acutangula. Roxb., in 

 Behar (Barn, 6-vi-07) ; and a Sphingid was seen on them at 

 Anand, Gujerat (l-xi-02^. 



Ipomoea rubroeoerulea, Hook., has fairly plentiful honey 

 in a tube 9 mm. deep, for which Anthophora zonata visits in 

 Calcutta (8— 15-ix-01). One of the five stamens equals the 

 style ; so that its anther may possibly pollinate the stigma. 

 Anthophora zonata, in visiting the flower, settles on the sexual 

 organs and scatters the pollen so that it may be found on the 

 corolla after a visit. 



Tnnn,ofi«. tmnieulata. R. Br., was seen visited by Xylocopa 



near 



aestuans persistently for honey (Calcutta, 29-vii-07, and 

 Bombay. l9-ix-08). Xylocopas are recorded as biting through 

 Ipomoea flowers in Singapore and Java (Ridley in Journ. Roy. 

 As. Soc, Straits Branch, No. 34, p. 229, and Kunth, Hand- 

 buch d. Bliitenbiobgie, III. part 2, p. 53) ; but in a general way 

 these showy members of the genus appear suited better for 

 their visits than for those of other insects. 



X latipes has been observed to rob Torenia Fournieri, 

 Linden., of its honey by biting through the corolla-tube just 

 above the calyx (Calcutta, 13-ix-Ol). 



It will be useful, before proceeding, to enumerate the
