46 THE HEAD. 



The parts of an antenna may next be observed, as 

 follows : 



a. The Tondu^ — the orifice or depression in the head 

 of the insect that receives the antenna. 



b. The Scape^ or first joint ; the base of this is called 

 the hulb^ and is inserted in the torulus. 



c. The Pedicelliis is the second joint, and is often the 

 least conspicuous joint of the antenna ; it is a hinge or 

 pivot on wliich the upper members turn. 



d. The Clavola are the remaining joints of the anten- 

 na taken together; they form the greatest part of it, 

 and at the extremity of the last joint exercise the func- 

 tions of touch, &c. 



By the term clothing of antennje, is indicated the 

 down or hairs of various kinds with which they are gen- 

 erally covered. 



The Suhfacies demand but a moment's attention. 

 Under this term may be included, 1st, the collum or 

 neck, or at least the joint by which the head is joined to 

 the thorax ; and 2d, ihe' jugulu77iy or throat, placed be- 

 tween the cheeks.
