PARTIAL ORISMOLOGY. 



1. Situation of the Antenna 1 . 



FRONTAL (ant. frontales}, they are called when they are inserted 

 directly upon the brow (Bees, PL VI. f. 8, c, c). 



PREOCULAR (ant. prceoculares}, are such as are inserted close to the 

 front of the eyes (Carabus, PI. III. f. 11 and 13, y, y, y). 



INTEROCULAR (a. interoculares), when they are placed between 

 both the eyes. 



EXTRA-OCULAR (a. extra-ocular es), when placed very distant from 

 the eyes. 



INOCULAR (a. inoculares), when the eye surrounds the base of the 

 antennae (Cerambyx). 



INFRA-OCULAR (a. infra-oculares), when inserted beneath the eyes. 



When they are placed, as is usual, upon the upper part of the head, 

 they are called SUPERIOR (a.superiores); but when beneath, INFERIOR 

 (a. inferiores). 



When their basal joints are inserted very closely together, they are 

 called APPROXIMATE (a. approximates) ; but when they are wide apart 

 they are styled DISTANT (a. distantes). 



2. Relation of the Antennae to the Body. 



ELONGATE (elongates), when of the same length as the body (Lep- 

 tura). 



LONGER (longiores), when longer than the body (Saperda). 



VERY LONG (longissimce'), when they are considerably longer than 

 the body (Lamia cedilis), Fab.). 



SHORT (breves'), when about the length of the head. 



SHORTER (breviores), when they are longer than the head, but 

 shorter than the body. 



VERY SHORT (jbrevissim.ce}, when not so long as the head. 



3. Forms of entire Antennae. 



Antennae which entirely consist of equal joints are called EQUAL 

 (equales), whereas those whose joints are dissimilar receive the name of 

 UNEQUAL (inequales~). Both kinds are subjected to various differences, 

 which we will now proceed to consider.
