stouter ; in the pubescence being much denser ; in the front being much deeply excavated 

 and without any keel; in the pro- and mesothorax having much fewer punctures (there 

 are only some fifteen on the raiddle lobe of the mesonotum); in the furrow in the centre 

 of the lateral lobes of mesonotum being almost obsolete; in the reticulation on the 

 metathorax being stronger; in the petiole being stouter, more produced at the apex 

 beneath, and furrowed laterally; in the praebrachial transverse nervure being received 

 nearer the base of the Stigma, so that the part of the first cubital cellule bounded by it is 

 longer than that bounded by the nervure and the apex of the stigma, the opposite being 

 the case with E. laevigata; the nervure itself being also distinctly curved; the first cubi- 

 tal cellule is shorter and wider, being nearly as long as broad, while is laevigata it is 

 longer than broad; the base on the lower side of the cellule in laevigata, too, forming 

 a sharp angle at its juncture whit the recurrent nervure, and not, as in the present 

 species, a curve; the recurrent nervure is distinctly curved, is not interstitial, but is 

 joined to the cubitus by a short pedicel. The mandibles have one large apical tooth.«

Ausser E. appendigaster kommt ferner noch die bereits unter den Arten der orien- 

 talischen Region beschriebene, auf den Philippinen verbreitete E. impresso, in dieser 

 Region vor, und zwar auf den Pelew- (Palau-) Inseln, Fitschi- und Freundschafts - 

 (Tonga-) Inseln.
