having the first pair of wings modified to form hard 
wing-cases for the second pair, are many handsome, 
large, and often fantastically shaped specimens, such as 
the horned stag-beetle (Megasoma) of immense size ; the 
horned rhinoceros-beetle (Phanseus) ; the cocoa-nut root- 
boring beetle (Scarabaeus) with larvae and pupae; the long- 
legged, parti-coloured harlequin beetle (Acrocinus) ; the 
large and striking-looking sawyer or carpenter beetle 
(Prionus) with long and powerful serrated mandibles 
by means of which it cuts off branches of trees ; the 
giant Buprestid with golden purple wings often used for 
necklaces ; the proboscis beetles or weevils (Curculio) , 
of which the larvae of one form (Calandra) are 
eaten under the name of grou-grou worm and are 
highly esteemed ; the spring-beetles (Elater) some of 
which are luminous and known as " three lights" 
(Pyrophorus) , with two oval luminous spots on the 
sides of the thorax, popularly regarded as eyes — the true 
eyes, however, being in front on the head ; the various 
forms of fireflies, cocao-boring beetles, and lady-birds, 
and others. Of the group of the flies, midges, gnats, 
and mosquitoes (Diptera), forms distinguished by the 
possession of one pair ot wings, the hinder pair being 
represented only by knobs, a few forms are shewn ; 
while a larger series represents the bees, wasps (mara- 
buntas), and ants (Hyrnenoptera), forms distinguished 
by the possession, usually, of four membranous wings, 
and of special mouth organs for biting or sucking pur- 
poses. In this group alone, among insefts, are found 
forms capable of stinging, owing to the presence of a 
long pointed organ connected with an acrid gland at the 
end of the abdomen. Nests of various species of this
