Flies such as Syrphids and Muscids are at times quite com- 

 mon on open flowers. 



Sun-Birds. 



Bird fertilisation is much less common in the topics of the 

 Old World than in the tropdc-s of the New. However there is one 

 little sun-bird, which visits flowers in the Peninsula commonly, 

 namely Cyrtostomus pectoralis, Horsf.

 following flowers: — 



Hibiscus Rosa-sinensis, Linn., and its garden hybrids, com- 

 monly.

 corded as visitors in Zanzibar, India and Java to them. Russelia 

 jvncea has been recorded as bird-visited in India, and Canna as 

 bird-visited in South America and South Africa. 



The common Malayan squirrel, sometimes goes to flowers that, 

 offer plenty of sweetness such as Erythr-ina or Durio, where the 

 destruction done is out of all proportion to the good.
