be regarded as divisible into four parts : the insertion 
or hinge, (cardo) which is the lowest portion by 
which it articulates with the throat, and which is 
usually placed nearly at right angles with the follow- 
ing part. The latter is the stalk, ( stipes ) generally 
pretty strong and thick, at least in its upper part, 
although frequently it is soft and membranous 
beneath. Attached to this, on its outer side, is a 
small portion which has been named the feeler-bearer 
(squame palpifere of Strauss,) because the maxillary 
palpus is always inserted on its outer edge. The 
terminal portion of the maxilla, which usually ap- 
pears in the shape of a hook,* ciliated on its inner 
edge, and frequently toothed at its extremity, is the 
maxillary lobe, ( internal lobe of Latreille, lacinia of 
Macleay.) This, which is an important part, as it 
acts immediately upon the food, is very often simple, 
but at other times it is divided into two pieces, in 
which case the one is called the external, the other 
the internal lobe of the maxilla. The external lobe 
is sometimes called the galea or helmet, (this is its 
appropriate name among the Orthoptera) but when 
it is jointed and palpiform, as it frequently is among 
the carnivorous Coleoptera, it is commonly described 
as the internal maxillary palpus. The maxillary pal- 
pus properly so called, is a pretty long, jointed, com- 
monly filiform process, the presence of which always 
distinguishes the maxillse from the mandibles. The 
* The lobe of the maxilla? is occasionally terminated by a 
moveable claw, as may be seen in certain Orthoptera and the 
tribe of Cicindelidae or tiger-beetles.
