makes considerable additions to the Australian Curculionide, 
describes a new Mantis from Pará, and gives a classification of — 
the Homoptera. Thirteen families of this sub-order are defined, — 
exclusive of the Aphid, Coccide, etc. (Phytophthiria), which 
are considered to belong to a lower group, and also of the Thrip- 
idz, which he regards as higher. C. O. Waterhouse describes 
nine new Longicorns, three Buprestids and four Cetoniids from 
Madagascar, and some Buprestids and Heteromera from various 
localities. . Wood Mason describes two new Indian Papilios, l 
and notes that the scentless group to which one of them belongs _ 
mimics the strong-scented and nauseous Philoxenus group—— —
