 Soldier. Head capsule pale yellow 

 cuticle pale yellow. 



Head capsule in plan view constricted behind antennae, posterior margin evenly rounded ; 

 nose rather thick, conical. In profile nearly straight, sometimes with slight depression in front 

 of rounded posterior lobe ; antennae, II, III and V subequal, IV shorter. Conspicuous setae 

 of head consist of six to eight in three or four pairs approximately in line across base of nose in 

 front of constriction, and a similar number on posterior lobe behind constriction.

E. convergens differs in the imago from E. bipartitus by the smaller ocelli, more 

 distant from the eyes, slightly less inflated postclypeus, and shorter hind tibia. 

 E. abruptus has a different fontanelle and more inflated postclypeus. The differences 

 from E. aquilinus and E. undulans are discussed under those species. In the soldier, 

 E. aquilinus and E. bipartitus have fewer head setae, and E. abruptus and E. undulans 

 thinner noses.
