where they are not easily seen. The rough bark of the tree 

 varies from rather light to dark brown and is broken into 

 rectangular pieces. On the stem are holes where the smaller 

 dead branches have dropped out. The tree thus affords 

 shelter and the bark colour protection. [A sketch showed 

 that the flies resting on the bark resemble the scars where 

 the branches have fallen.] 



" The Lepidoptera fly mostly high to the top flowers. Those 

 sent came down lower. The tree was crowded with various 

 bees. I think I have sent at least one of each — also blow flies 

 and house flies (few). 



" The proportions of the species in the collection sent is a 

 true criterion of their relative numbers on the tree except with 

 the bees, which I did not take freely. My method of taking 

 was to hold the mouth of the spirit bottle over or under the 

 flower, which thus made a stopper and the insect fell in. They 

 were more or less drunk with honey. I did the same with a 

 larger-mouthed cyanide bottle for the Lepidoptera. 



" Each year this tree is covered with insects. Sometimes 

 it flowers more freely, sometimes less than this year. You 

 would enjoy the sight. One year a man working in the garden 

 remarked to me, ' My word, it's a regular aquarium.' " 



Dr. Otto Stapf, F.K.S., of Kew, had kindly given the follow- 

 ing information concerning the tree : — 



'■ The variety rosea of Eucalyptus calophylla, R. Br., is men- 

 tioned in Guilfoyle, ' Australian Plants,' 1911, p. 161. There 

 is no author quoted for the variety, nor can I trace it farther 

 back, and it seems therefore to be Guilfoyle's creation. He 

 says nothing about its cultivation. E. calophylla was recom- 

 mended for planting in avenues as early as 1860-61 (see Ferd. 

 v. Mueller, ' Fragm.' 11, p. 36). He also mentions it as suffer- 

 ing from frosts at Melbourne in his ' Eucalyptographia,' 1879 

 (no pagination, but alphabetical arrangement). It was grown 

 in the Melbourne Botanic GJarden in 1882 (Guilf., ' Cat. Mel- 

 bourne Bot. Gard., 64; 1883). 



" Tlie species is confined to W. Australia. A form with pink 

 filaments is mentioned by Ferd. v. Mueller in his ' Eucalyp- 

 togr.' as very rare, and I assume it is the var. rosea of Guilfoyle. 

 E. calophylla has for a long time been known as a ' bee-tree.' "
