Now recalls a Melastoma visited by some small Cetoniadae and bees (Xylocopa) in Malay Archipelago.

My dear Mr Darwin
It has just occurred to me, that I have seen insects on Melastomas. A small shrubby species is abundant in all the cleared waste grounds in the Malay Islands, & I now distinctly recollect having frequently taken small Cetoniadæ of the genus Valgus from the flowers. The large wood boring bees (Xylocopa) also visit the flowers, & the whole plants often swarm with small black ants.
I remember also distinctly having seen the flowers much eaten by insects.
The Plant however is so common close to Singapore that I will write to one of my friends there to observe & make a list of all the insects, that visit it.
Hoping these few facts may be useful | I remain | My dear Mr Darwin | Yours very
faithfully | Alfred R. Wallace
Charles Darwin Esq
