 just in front of the insertion of the abdomen; above, the surface is 

 lineated by regular lines or rugae, slightly diverging outwards and 

 downwards; no cross rugae ; the lines are not continuous, but those 

 beginning at the base of the propodeum terminate unequally, and in 

 their interspaces new lines begin. Tibial yellow, often striped with 

 fuscous externally, and with an inner black stripe, testaceous at tip ; 

 tarsi yellow, terminal joints dark fuscous. Middle legs colored like 

 the anterior pair, tips of the tibiae are blacker. Hind trochanters and
