Capitated , or increasing in thickness to the extremity, tlie last 
joint being considerably larger and rounder than the rest. 
Fissile , similar to the last; but the head or extreme joint is di- 
vided longitudinally into different parts, or laminae, as in the Sca- 
rabæi. 
Pectinated , or comb-wise, having lateral appendices, as in some 
of the moths, and elateres. 
Bearded , or like a feather. 
When the antennae are not so long as the body, they are termed 
Ireviores , or short ; médiocres , or middling, when of equal length ; 
and longiores , or long, when longer than the body. 
In most of them, the mouth is under the head ; in some few, it is 
placed in the breast: the mouth contains the palpi, or feelers, the 
maxillæ, or jaws, and the lingua, or tongue. It is observable, some 
insects have no mouth. 
The proboscis, or rostrum, is the mouth extended, ending in a 
point: in some, it inclines towards the breast, as in the cicada, nepa, 
notonecta, cimex, aphis, and more particularly in some curculiones. 
The palpi, or feelers, are mostly from four to six in number, ge- 
nerally articulated, and with which they support their food. 
Some insects have only two maxillæ, or jaws; some four: in 
others they exceed that number. These are fixed horizontally ; the 
inner edges in some being jagged, appearing like teeth. 
The lingua, or tongue, in the butterfly is taper and spiral : in the 
nausea fly, it is tubular and fleshy, like a proboscis. Many insects 
have no tongue, but instead, use their feet or wings. 
Ti uncus, the trunk, is that part between the head and abdomen,
