upper lobe in G. Natator*. The lower lobe of the 
maxille in this tribe represents a laniary mandible”; and 
in the Anoplognathide, a New Holland tribe of chafers, 
in which it is, as it were, broken, the lobe forming an 
angle with the stalk, it is concavo-convex and obtuse, 
and somewhat figures a molary tooth *. In the first tribe 
into which the bees have been divided (Melitta K.), the 
lobe is often linear or strap-shaped, and bifid at the 
apex; and in the second (4pis K.) lanceolate and intire". 
In Cerocoma it is long and narrow*. More variations in 
form might be named, but these are sufficient to give you 
a general idea of them in this respect. _ With regard to 
their clothing, I have not much to observe—in examin- 
ing the Predaceous beetles you will observe, that the in- 
terior margin of the lower incurved lobe is fringed with 
stiff bristles or slender spines, and in many other beetles 
either one or both lobes have a thick coating or brush 
of stiffish hairs‘; but in several cases only the apex of 
the lobe is hairy. In the Orthoptera order, and many 
of the Melolonthid@ or chafers, the whole mavilla is with- 
out hairs, or nearly so. 
The appendages of the mazille are next to be noticed. 
These are principally their claws, or laniary teeth; for 
they are seldom armed with incisive or molary teeth. 
The whole tribe of Predaceous beetles, with few excep- 
tions, have the inner lobe of their mavxilla armed with a 
terminal claw, which in the Cicindelide articulates with
