Australia and New Zealand there is aucity of species. He 
considers that the present dietribmakicn of the Gentianee is not to be 
accounted for by migration from any given centre, whence diffusion

the Indo-Malay —— yet the Zapiride were widely distributed

in Pl 
and Miocene times their distribution was substa taantially similar to 
those now extant. Could the age of the first appearance of Diptera, 
Hymenoptera, and Lepidoptera, provided with long haustra, be 
indicated, then specialization of types and the problem of the 
distribution of the Gentianea anight t be Gareorer: guessed.
