 longer than thick ; second cubital cell quadrangular, longer than wide, 

 the first recurrent received at about its apical fourth. 



Melissodes Latr. (pars). 



15. Marginal cell at apex broadly truncate, with an appendage. 



First cubital cell, along the cubitus, not longer than the second, the latter 

 somewhat narrowed above, and receiving the first recurrent nervure 

 at its extreme apex, or just before the second transverse cubitus; third 

 cubital cell a little the longest cell ; first discoidal cell shorter than the 

 marginal; dorsal abdominal segments broadly and sharply depressed 

 at apex, the depressed portion being differently sculptured from the 

 basal portion; no fasciae on segments; pygidial plate subtriangular, 

 rounded at apex ; claws in 9 simple, in % cleft; clypeus yellow in 

 both sexes; mandibles bidentate : eyes in % convergent above, the 

 face narrowed; flagellum subclavate, the first joint of flagellum very 

 long Meliturga Latr. 



First cubital cell, along the cubitus, longer than the second, the latter quad- 

 rate, receiving the first recurrent nervure at its middle; legs densely 

 hairy, the middle, tibial spur simple; knee plate on hind tibia} want- 

 ing; claws cleft. Melitoma Latr. 



16. Second cubital cell wider (higher) than long 19. 



Second cubital cell as long or longer than wide. 



First and second cubital cells, along the cubitus, of an equal length or 

 nearly, the third distinctly shorter and smaller than the others; first 

 recurrent nervure received by the second cubital cell a little beyond 

 its middle; clypeus prominent, bicarinate, the carina?, convergent pos- 

 teriorly ; mandibles at apex tridentate; maxillary palpi very short, 

 2-jointed, the first joint short. 



Epicharis Klug ? = Melissoptila Holmh. 



17. Clypeus in % not pale or yellow, at most and very rarely, with a pale stripe ; 



antennae in % not or very little longer than in the 9 ; maxillary palpi 

 4-6 jointed 21. 



Clypeus in % more or less yellow (rarely black), in 9 black ; antennae in % 

 very much longer than in the 9 ° 1- deformed ; maxillary palpi 3, 4, 5-6 

 jointed 1*. 



Clypeus in both sexes yellow or white; antennse short and much alike in both 

 sexes; recurrent nervures received respectively by the second and 

 third cubital cells a little before the first and second cubiti. 

 Marginal cell at apex broadly obliquely truncate ; dorsal abdominal seg- 

 ments broadly, sharply depressed at apex, the depressed part differ- 

 ently sculptured from the basal portion ; claws in 9 simple, in % 

 cleft; eyes in % convergent above; mandibles bidentate; flagellum 



subclavate Melit urga Latr. 



Marginal cell at apex not truncate, narrowly rounded, or somewhat pointed ; 

 dorsal abdominal segments at apex notdepressed, uniformly sculptured . 

 claws cleft in both sexes; eyes in % not convergent above; mandibles 

 simple; flagellum filiform IVIeliturgopsis Ashm. n. g. 



18. First and second cubital cells, along the cubitus, equal or nearly, considerably 



longer than wide, but shorter than the third: first recurrent nervure
