12 AMBLISPA. 



entirely concealing the base of the Ugula. The Ligula (fig. A, h) or 

 intermediate division is composed also of two segments, here gene- 

 rally divided l)y a sutural line ; the lower or basilar is the part 

 from wliich the labial palpi arise ; it is frequently much enlarged, and 

 sometimes entii'ely conceals the apical segment (this latter (fig. A, c), 

 when visible, is for the most part produced anteriorly in the form of 

 nn obovatc or oblong lobe). The variations in shape of the mentiim 

 and basilar segment of the ligiila afford most important scientific 

 characters, and, from their exposed position on the under side of the 

 mouth, they can be easily examined -without dissection.
