a well-developed male specimen, are about double this 
length, giving the creature a reach from finger to finger, 
so to speak, of over a foot in extent. 
It might be supposed that its size and vivid colouring 
would make the beetle a very conspicuous insect, but 
the meagre and somewhat diverse accounts of its habits 
given by travellers hardly support this idea. It is fairly 
often found on tree-trunks, and is then, indeed, a very 
: conspicuous object ; but it seems to be chiefly nocturnal 
in habit, remaining concealed during the day within the 
burrows that the larva has made in the trunks of trees, 
principally those of a kind of indiarubber tree. From 
these it emerges in the early morning to feed on the 
exuded sap of the tree, of which it is very fond. 
One writer describes it as living amongst the branches, 
where the length of its limbs gives it a most graceful

that when disturbed its long forelegs adopt a “ rigid attitude of defence.” That this immense 
development of the forelegs is confined to the male sex only would indicate that their chief function 
is to hold the female in some peculiar way, but no observations on the subject are to hand.

RADIOLARIANS

Ir the Radiolaria were as large as those shown in the accompanying illustrations they would com- 
mand our attention and admiration. We should provide special glass cases for them, or cabinets 
in which we could display them to the best advantage. 
At times we should take them out carefully and show 
them with as much pride as if they were of equal value 
with the marvellous concentric ivory balls of Canton, 
but, unfortunately, they are only known to a very few 
of our population, although there are teeming millions 
of them in all the oceans of the world. 
The Radiolaria receive their name from the fact that 
several parts of their structure, and especially their 
feelers, radiate as from a central point. They are all 
microscopic. This fact alone is sufficient to make them 
all the more wonderful, for they range in diameter from 
the tenth to the one-hundred-and-fiftieth of an inch! 
The living creatures are of many colours and are by no 
SS means of simple structure, notwithstanding that they are
