of the Mazilla, incumbent on the inner one. In 
the Predaceous Beetles this lobe is biarticulate and 
palpiform *; and in Goerzus olens, &c. it also con- 
sists of two joints’. It is called the Galea by Fabri- 
cius, in Orthoptera, &c.° 
Losus Inrerror (the Lower-lobe). The inner lobe 
of the Mawilla, covered by the outer one‘. 
C. Uneuss (the Claws). One or more corneous sharp 
claws which arm the lobes of the Mazilla‘t. In the 
Predaceous Beetles there is only one terminating 
the lower lobe, with which, in Ciczndela, it articu-

several.

Lineva (the Tongue). The organ situated within 
the Labzum or emerging from it, by which insects 
in many cases collect their food and pass it down 
to the Pharyna, situated at its roots above. It va- 
vies considerably in different orders and tribes. In 
the Orthoptera, Libellulina, &c. it is linguiform, 
and quite distinct from the Labium&; it appears 
also distinct in the Zamellicorn beetles, &c." In many
