Antigonon leptopits, Hook., in Malacca. 



Dictyosperma album, W. & D., in Singapore. 



Oreodo.iu regia, H. B. K., in Singapore 



Nipa fructicans, Tlnmb., at Port Swettenham, collecting 

 pollen. 



Cocos niicifera, Linn., in Singapore. 



Hovialonema coerule.scens, Jungh., in the Selandar forest, 

 Malacca, imprisoned in closed spathes. 



Upon the flowers of such plants as Cassia and Melastoma, as it 

 visits the stamens only, it does no good in the way of pollinating 

 them. 



Small undetermined Apiids have been seen upon : — 



Melastoma malabafJiricum, Linn., in Singapore. 



Pelrea rugosa, H. B. & K., in Singapore. 



AsystaMa travancorica, Bedd., in Singapore. 



Asystasia coromandeliana, Nees, in Singapore and Malacca. 



Ipomoea pes-caprae. Sweet, on Pulau Tiuman. 



Mimosa pudica, Linn., at Batang Malaka, Malacca. 



Afitigonon lepiopus, Hook., in Malacca and Klang. 



Vespidae. 



Wasps often eat as much animal food as vegetable food, and 

 therefore are less useful to flowers than the bees. The big Vespa 

 cincfa. Fabr., to which Mr. Ridley ascribes the pollination of 

 arammatophyllum speciosum (Journal of the Straits Branch of the 

 Royal Asiatic Society, No. 44, 1905, p. 228) goes to flowers at 

 - times for honey, and at times to prey on bees. The writer has never 

 seen it pollinating any orchids, but has seen it sucking honey upon 

 the flowers of Viti■^<' in Penang and of Antigonon leptopus in 

 Malacca. 



Other wasps have been seen upon the flowers of Morinda citri- 

 folia, Linn., near Tampin, and Scypliiphora hydrophyllacea, 

 Gaertn., at Port Swettenham, on Baeckia frutescens, Lmn., at 

 Penang', and on Emhelia dasytliyrsa, Miq., near Alor Gajah. 



Butterflies and Moths. 



Flowers particularly suited for fertilisation by butterflies have 

 not come under observation to any great degree. Among the fol- 

 lowing, only I.rora and Scyphiphora are really suited. 



Eugenia lineata, Duthie, many butterflies in Singapore. 



Miissaenda erythrophylla, Sch., a Papilio, in Singapore. 



Ixora niacrothyrsa, B. & T., a Papilio, in Penang. 



Yeronia cinerea. Less., Lycaenids, in Singapore. 



Roupellia grata, Wall., a Hesperid, in Penang. 



Lantana Camara, Linn., two or three species of butterflies at 

 Tanjong Malim.
