ordinary shape. Etitrachelus temmincki, from the foot of Kina 
Balu, B, N. Borneo, may be called the giraffe amongst the 
beetles, from its enormously elongated thorax (see pi- XV, fig. 4)* 
Equally curious is Diurus furcUlatiu in which the elytra at their 
hinder end are drawn out into a kind of fork. It is figured in 
Wallace's ' Malay Archipelago.' 
The Longicorns [Cerambyddae and Lamiidae) include many 
large and handsome species. In size stands first Dysiahts melas. 
Its elytra are of a deep chestnut colour, the rest of the body is 
black. It has enormous legs and antennae. The largest speci- 
men exhibited is from Bukit Timah. One of the most common 
local Longicorns is Baioccra octmnacidata, grey with eight white 
spots. Xyiorhiza venosa is remarkable through its curiously 
striated elytra which give it the appearance of a piece of rotten 
wood (see pL XV, fig. 3). 
Of the endless number of families of smaller beetles we 
mention only the Shield or Tortoise Beetles {Cassididae) in 
which the elytra are curiously expanded, as in the various 
^p^ci^'s oi Aspidmnorpha \ and the Lady-birds {Cocci neUidae) of 
which many hundred species have been described from all parts 
of the world. These familiar little beetles make themselves 
useful by destroying plant-lice and other injurious insects. 
CADDIS FLIES AND ANT LIONS 
(Neitroptera.) 
This small group, including only Caddis Flies and Ant 
Lions, undergoes a complete metamorphosis and differs thus 
from the next one, the Dragonflies and Termites, which they 
otherwise resemble in their general appearance and in their 
mouthparts which are adapted to biting and grinding- None 
are exhibited. 
DRAGONFLIES AND TERMITES 
( Pseiidonenropiera J 
These insects, although resembling the Neuroptera in 
in their outer appearance, are really more closely allied to the 
Grasshoppers and other insects which constitute the next order* 
the Orthoptem. The Dragonflies and Termites undergo no 
metamorphosis. Their mouthparts are biting, and they have 
tw^o pairs of wings both of which are thin and membranous. 
They differ thus from the Grasfthoppers and other Orthoptera
