Queen. Much smaller than e. g. the queen of E. mag- 

 nus Frogg., whitish yellow with head, thoracic segments, 

 legs, and ten chitinous plates of the abdomen darker, 

 the first of the latter rounded at the sides, the following 

 se ven rectangular, the two last smaller and rounded a t 

 the sides, the four first segments very much wider and 

 more swelled than the following ones (ocoasionally or nor- 

 mally?).

 head 1,37 mm, breadth of head l,i8 mm, length of prothorax 

 0,59 mm, breadth of prothorax 0,8 9 mm, breadth of abdomen

Soldier (Text Fig. 19, 20 b). Similar to the soldier of i^. 

 fumipennis Walk, but head smaller with the sides more taper- 

 ing to the snout, much lighter in colour, light fuscous, with 

 a broad patch in the middle of the hind head and the region 

 round the cleft of antennse much lighter; the shape of the 

 head as shown by the profile fig. entirely different ; antennse 

 12-jointed (always) basal joint fairly stout, but not quite so 

 broad as in E. fumipennis Walk., 2nd much smaller, about 

 a third part in length of the basal one, 3rd longer than 

 2nd, much broader at the tip than at the base, 4th not quite 

 so long as the 3rd, longer than broad, much longer and 

 much more rounded at the sides than in E. fumipennis Walk.,
