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 

 (sgua me palpi/ere 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, facinia of 

 Macleay.) This, which is an important part, as h 

 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 maxillaB from the mandibles. The 



* The lobe of the maxillae is occasionally terminated by a 

 moveable claw, as may be seen in certain Orthoptera and the 

 tribe of Cicindelidae or tiger-beetles.
