110 GRAMMAR OF ENTOMOLOGY. 



379. Clavate antennae (antennce clavigerce,) 

 are terminated in a gradual club, the shaft being 

 generally long, slender, and filiform. 



380. Capitate 'antennae (antennce capitatce) are 

 those in which the knob is more abrupt, and 

 strongly marked : the knob is sometimes solid, 

 consisting of a single joint, sometimes composed 

 of many joints. 



381. Perfoliate antennae (antennce perforates) 

 are those in which a portion of each joint is 

 dilated and flattened ; and the remaining portion 

 being cylindrical and slender, appears like a 

 thread, on which the dilated portions are strung. 



382. Setigerous antennae (antennae setigerce), 

 are those in which the basal joints are stout and 

 short, the third being much the largest, of various 

 shapes, and having the remaining joints, which are 

 formed into a kind of bristle, attached on one side 

 of it, often at a right angle. 



383. Antennae are of various kinds, besides 

 those here described ; but all the common forms 

 may be found in the foregoing list : when other 

 forms occur, their peculiarities are described : no 

 general name is applied to them. 



384. The length as well as the structure of 

 antennae is very various ; sometimes they are so 

 short as to be concealed from the sight in the little 

 cavities in which they stand ; sometimes they are 

 five times the length of the body. 



385. The eyes of an insect commonly form the
