9 . Black. Head witli the mouth piceous or dark ferrugineous ; eyes 

 very prominent. Antennae slender and nearly as long as the body ; im- 

 maculate. Thorax t^ibbulous ; metathorax scabrous ; areola elongate and 

 entire, centrally dilated with no costulae; petiolar area short; spiracles 

 transverse and linear. Scutellum black, rarely in 9 apically binotated 

 with flavous. Abdomen immaculate, narrower than, and with basal seg- 

 ment about one-third the breadth of, the thorax ; first segment with tuber- 

 cles distinctly before the centre, between which and the base it is 

 obsoletely punctate and pilose ; apical ventral segments deflexed and com- 

 pressed ; terebra one fourth the length of abdomen. Legs elongate, 

 slender, black ; front tibiae and apical half of their femora infuscate ; 

 intermediate legs, including apices of their femora, darker ; anterior tibiae 

 and the front femora internally testaceous. Wings with the stigma testa- 

 ceous and areolet subscssile, nervellus intercepting far above the centre. 

 Length, 14 — 15 mm. 



(J . Black. Head with the face flavous, except triangularly beneath the 

 scrobes ; apices of mandibles piceous. Antennae very slender, as long as 

 the body and apically reflexed. Thorax immaculate with the metathorax 

 dull. Scutellum mainly white. Abdomen black and narrow ; basal seg- 

 ment subpetiolate and hardly narrower than the second, with the tubercles 

 a little before the centre; third and following segments attenuate to anus; 

 ventral valvulae exserted. Legs pale testaceous with the hind ones 

 obscurely badious; coxae black with the front ones entirely, and the inter- 

 mediate beneath flavous. Wings with stigma and tegulae testaceous ; 

 areolet large, triangular and subsessile. 



The two 9 9 in the British Museum, from Desvignes' and Stephen's 

 collections, are like black legged E. calobatiis, but are certainly a good 

 species, with testaceous stigma and the basal half of the first segment 

 closely and very finely punctate. There, too, is a single $ of E. facialis, 

 which appears to me to be undoubtedly the opposite sex of E. ?iiaunis, 

 this is Desvignes' type ; it has the anterior legs pale and the scutellum 

 broadly white at its apex. The J differs only in having the scutellum 

 pale, the metathoracic areola obsolete, basal segment apically narrower^ 

 anterior femora and tibiae fulvous with hardly darker tarsi and the mandi- 

 bles except apically, clypeus, face except triangularly below the antennae, 

 and the anterior coxae and trochanters all flavous. 



No one has ventured to record this species since it was first described 

 as British ; it certainly has not occured to me, but is very probably mixed 

 with E. caloha/us in collections.
