the submentum by the cardines, are found the maxillce 
(Fig. lo, //), or lower jaws, so called from the func- 
tion they perform. These are hollowed out and fit 
over the mentum on either side, and have stiff hairs 
along the front edges. They have also feelers (Fig. lo, 
i) called maxillary palpi, furnished at the end with 
hairs (Fig. ii, b), described by Dr. Hicks (65). 
Fig. II. — Labial and Maxillary Palps. 
The maxillae are composed of two joints, the upper 
harder part, called the stipe (stipes) (Fig. 10, k), 
having strong hairs along its front edge, and the lower 
more delicate part (Fig. 10, h) forming the blade 
(lacinia)^ furnished sparingly with hairs. 
By referring to the sections taken from Wolff’s 
(170) monograph (Fig. 13, a, b), it will be seen 
that the maxillae (t 7 i -?n) and labial palpi (/ 1 ) together 
form a tube in which the enclosed tongue can move 
backwards and forw^ards. 
In repose, or wTen the tongue is drawm in, it wall 
be seen that the tube is flattened (Fig. 13, b), the tongue 
occupying the centre, so that in reality tw^o tubes (p 0) 
are formed, one on either side. When, how^ever, the 
tongue is extended, the four parts assume the shape of 
Fig. 13, A, and form a large tube {p 0), The first 
double and then single tube leads to the opening of 
the mouth. The ligula,, or tongue (Fig. 10, d?), is
