colors and large ocellated spots as Drusilla. Equally remarka- 
ble is the fact that the small island of Amboina produces 
larger-sized butterflies than any of the larger islands which sur- 
it. This is the case with at least a dozen butterflies 
belonging to many distinct genera,* so that it is impossible to 
attribute it to other than some local influence. In Celebes, as 
I have elsewhere pointed out,t we have a peculiar form of wing 
and much larger size running through a whole series of distinct 
butterflies, and this seems to take the place of any specialty in 
color. 
From the Fiji Islands we have comparatively few butterflies, 
but there are several species of Diadema of unusually pale colors, 
some almost white. 
The Philipine Islands seem to have the peculiarity of devel- 
oping metallic colors. We tind there at least three species 0 
upleat not closely related, and all of more intense metallic 
luster than their allies in other islands. Here also we have one 
of the large yellow Ornithopteree (O. Magellanus), whose hind 
wings glow with an intense opaline luster not found in any 
other species of the entire group; and an Adolvas§ is larger and 
of more brilliant metallic coloring than any other species int 
Archipelago. In these islands also we find the extensive and 
wonderful genus of weevils, Pachyrhynchus, which in their bril- 
liant metallic coloring surpass anything found in the whole 
eastern hemisphere, if not in the whole world. 
In the Andaman Islands, in the Bay of Bengal, there are a 
considerable number of peculiar species of prea hae
