I am very much obliged to you for these nicely set Bruchi, and I do not think it would be at all out of place, although two of the species are not British, to give figures of the three kinds (brachialis, rufipes, and tristis) as found in a cargo including beans and wild peas from Smyrna, together with barley. (The consignees were very much puzzled about them.) I also found rufimanus in one of the beans which I was opening, a lovely specimen, so perfect in its marking. But now, if you please, I very much wish for a little further help. I cannot find any reference to brachialis or tristis in any book I possess, excepting just the names in Calwer’s “Käferbuch.”
I have been not a little disappointed about Scolytus pruni. I found nice larvæ in a piece of plum bark with this infestation, and had a good figure taken, but I kept on watching the small number of specimens to be fairly certain of species, and to my vexation on development out came one as rugulosus!
With many thanks for your welcome and valuable help.

I am very much obliged to you for lending me the two vols. of “Deutsche Ent. Zeit.,” which will help me very much about those Bruchidæ—and more particularly with the specific distinctions which you have been good enough to give me. I will try not to keep the books over-long, and will return them carefully packed.
