On either side, near the junction of the ligula and mentum, 

 arises a jointed organ rarely absent, called the labial palpus 

 (Fig. 6, kk), or, together, the labial palpi. Just within the 

 angle formed by these latter and the ligula arise the para- 

 glossae (Fig. 15, d), one on either side. These are often 

 wanting.
