Cetoniides. 
AVallace lias published (Trans. Ent. Soc. Loud. 3rd ser. 
iv. pp. 519-GOl) a valuable catalogue of the known species of 
this group from the Malasian region. He indicates the pro- 
gress of our knowledge of the Malasian Cetoniides as follows : — 
Gory and Pcrcheron knew 45 species, Burmcister records 60, 
the British Museum ‘^‘^List^^ 74, and Lacordaire gives 85. 
Twenty-eight species have since been described by Thomson, 
Vollenhoven, and others; and the species described by A¥ allace 
in the present paper (diagnoses of which were published last year 
ill Proc. Ent. Soc. 1867, pp. xcii-xcvii; see Mlecord,"’ 1867, pp. 
256, 257) bring the total number to 181. AA^allace remarks that 
the number of species found in any one locality seems to be 
influenced, first by proximity to the continent, and next by the 
mass of the island.^^ Thus the peninsula of Malacca, though 
imperfectly explored, has 44 species, and Java only 46. The 
Philippines have only 32 species, Celebes 19, Ceram and Am- 
boyna 11, the Aru Islands 9, and New Guinea only 12. He 
adds that the same diminution is apparent if wx take the two 
great regions (Indian and Australian) into which he divides the 
archipelago, — the Indian region, including Java, Borneo, and 
the Philippines, having 114 species; while the Australian, ex- 
tending from Celebes to the Solomon Islands, has only 70. This 
distribution is shown in an elaborate tabular view at tlie end of 
the paper. Of the genera a larger proportion is common to the 
two great regions; but even here A¥ allace finds evidence in 
favour of his views. Thus 9 genera, namely, MycAeristis, Age- 
strata, Clerota, Plectrone, Chalcothea, Centrognathus, Rhagopte- 
ryx, Macroma, i\w(\.Eurcmina, arc peculiar to the Indian region; 
and 2 others, Heterorhina and Clintcria, are scarcely represented 
bc3^ond it. Three genera, ScMzorhinaf Anacamptorhina, and 
Sternoplas, are confined to the Australian region, and Lomaptera 
nearly so. A¥ allace figures the following species (/. c. plates
