Articulation, joint; this word is generally used to denote the 

 space between two joints; articulations are apparent, when 

 their distinction is obvious, and obsolete, when their separa-

 eleven articulations to each antenna, the Hemiptera four to 

 six, the Hymenoptera commonly thirteen in the males and 

 twelve in the females.
