Genus III. PARAJULUS Humbert Sl Saussure. 



Parajulus Humbert & Saussure, Revue et Mag. Zool., 155, 1869 {olmeciis). 



Eyes triangulai", elliptical or trapezoidal ; ocelli numerous, not arranged 

 in more than ten series. Antennae subfilifoim, scarcely subclavate, 

 second joint longest. Mandibulary combs, 9-10. Gnathochilarium 

 scarcely &ub-spatulate ; stipes not separated ; mentum bipartite, al- 

 most hidden ; lingual plate separated ; lingual lobes denticulated. 

 Number of segments uncertain, 40-70 ; sides striate. Last segment 

 more or less produced into a spine ; anal scale triangular or somewhat 

 rounded. Repugnatorial pore beginning on the sixth segment, placed 

 in the posterior part. Third segment apodous. Feet equaling the 

 width of tody, seventh joint longer than third ; second pair of feet 

 very strongly stunted or dwarfed. Mdle : First pair of legs enlarged, 

 six-jointed, the fourth largest. 



To this genus have been referred our lai-ger species of so-called 

 Julus ; from the latter genus it is easily separated by the num- 

 ber of mandibulary combs, by the second pair of legs, and the 

 first pair of the male. 



This genus is divisible into the foUoAving sub-genera : 



* Male : Promentum ver}" large, ovate, narrowing the lingual plates ; 

 first segment enlarged, sides very broad, almost sub-quadrate ; first
