yellow. Wings longer than the abdomen, cinereous; the 

 costal cell and the stigma testaceous; discal cell penta- 

 gonal; furcated cell about thrice as long as its stalk; the 

 third posterior cell narrow-, the fourth one on the con- 

 trary enlarged at the end. 



A single but well preserved pair from Ambarawa in 

 Java (Ludeking).

 gra ; pleuris et ventre pallidis ; antennis gracilibus , articulis

 Q. Long. 13,5 mm. 



Antennae slender; the two basal joints pale yellow ; the 

 third and following joints black, cylindrical, bare (the 

 last joints are absent in both specimens). Head testaceous; 

 orbits of the eyes whitish; palpi fuscous. Thorax on the 

 upper side cinereous with hardly any indication of longi- 

 tudinal stripes ; pleurae light grey. Abdomen testaceous , 

 with a black lateral stripe which is interrupted and bordered 

 with pale yellow ; underside and ovipositor yellowish ; the 

 tip of the latter chestnut-coloured , shining. Legs very long 

 and slender, uniformly testaceous; the tarsi infuscated. 

 Halteres fuscous. Wings longer than the abdomen, hyaline 

 with hardly any cinereous tinge and a rather clearly 

 defined tesliaceous stigma, which does not quite reach 

 the margin of the wing; the neuration calls to mind that 

 of the genus Megistocera; the two submarginal cells are 

 large , the inner one triangular ; discal cell pentagonal ; 

 furcated cell shortly pedunculated; axillar vein unusually 

 short. 



Two female specimens from Surinam, presented to the 

 Museum by Mr. Horst.
