head wide, the antennae in the $ reaching beyond the 

 apex of the spread wings. ) . . E. bellator, sp. nov. 



27. (26) Hyaline glabrous area of discocubital cell normal, well 



rounded below, often with a distinct chitinous sjiot; 

 clypeus not yellowish-white or cream-coloured except 

 along the orbits. Insects sometimes ferruginous like the 

 preceding, sometimes blackish or dark fuscous or parti- 

 coloured. 



28. (29) A usually nearly constant species in appearance, nearly 



black or dark blackish-fuscous, the discocubital cell 

 always with two chitinous spots, the outer one small or 

 minute and sometimes pallid or translucent ; antennae 

 of $ always extending far beyond the apices of the spread 

 wings; face in both sexes wider than in the following, 

 the eyes more strongly rounded outwardly. 



(Second and following abdominal segments, or some 

 of these, obscurely brownish or reddish tinged ; Kauai 

 specimens have the antennae and more or less of the 

 legs pale, yellowish-brown.) . . . E. dispilus, P. 



29. (28) A very variable species ferruginous or castaneous like 



E. bellator or blackish like dispilus or parti-coloured and 

 variegate with red and dark fuscous; discocubital cell 

 with a distinct chitinous spot or with this faint or totally 

 wanting, rarely with a minute pallid second spot present. 

 Face narrower than in any other species, the eyes less 

 rounded outwardly and the antennae of $ reach only 

 to the apex of the spread wings; carina of propodeum 

 highly variable, usually very distinct and well-developed 

 in the $, though sometimes (especially in undersized 

 examples) wanting, in the (J often faint or altogether 

 absent, but sometimes strongly developed as in the $. 

 (Pale orbital markings almost always widened beneath 

 the sinus of the eyes.) . . . E. castaneus, Ashm. 



30. (1) First or basal abscissa of the radius slightlj' and evenly 



thickened basally , without the somewhat irregular or sub- 

 sinuate thickening observed in nearly all other species ; no 

 glabrous hyaline area beneath the radius, but the hairs 

 are sparser in the part usually occupied by this area. 

 Mesonotum somewhat strongly compressed at the sides, 

 in such a way that the middle third of its width appears 

 elevated. 



(Thorax dorsally black, the scutellum and median 

 elevation of the mesonotum red; sides of thorax 

 reddish more or less suffused; basal abdominal seg-
