Has received letters of January and March on his return last month. Thanks for papers but has not received the list of longicorns of Australia. "The quantity of obscure species in my collections are beginning to frighten me." Has just packed over 13,000 specimens, but they are particularly poor in longicorns and Coleoptera generally. The geographical distribution of insects in the archipelago is far less strongly marked than that of birds and mammals, may be imputed to the greater liability of insects to accidental dispersion etc.
