the abdomen smooth. Basai abscissa of cubitus slightly roundly curved ; the récurrent nervure 

 received near the apex of the ist cubital cellule. 



The latéral keels on the 2»d abdominal segment converge slightly towards the apex 

 of the segment; suturiform articulation deep, closely, strongly striated, narrowed towards the 

 outer edge ; there are 110 latéral foveae. Sheaths of ovipositor, narrow, shortly haired, entirely 

 black. The 2 nd abdominal segment slightly shorter than the i st , nearly twice longer than the 

 width at the apex. Ventral segments with large, long black spots ; the basai 3 segments 

 together are slightly longer than the thorax. 



Cornes close to 5. rostratus Szép. which should be, inter alia, easily known by the 2nd 

 abdominal segment being „fast so lang wie breit." 



Megalommum Szép. 



1. Megalommum nigriceps sp. nov. 

 Wakobi, March. 



Black; the thorax and 4 front legs rufous, the legs paler than the thorax; the ist seg- 

 ment of the abdomen rufo testaceous, the area of a darker testaceous colour; the 4*, jth and 

 6 1 ' 1 narrowly at the apex and the whole of the 7* pale yellow; the hind tarsi for the greater 

 part fuscous. Wings long, dark fuscous; the nervures and stigma black, the nervures at the 

 base of the wings rufo-testaceous. Ç. 



Length 9 mm.; terebra 4 mm. 



Front and vertex smooth, shilling; the former furrowed down the middle, almost bare. 

 Face not so shining, sparsely covered with long pale hair. Mandibles testaceous, their apical 

 third black. Maxillae large, pale testaceous, densely covered with long pale pubescence. 

 Parapsidal furrows distinct on the basai slope. There is a transverse crenulated furrow at the 

 base of the scutellum. Médian segment covered with long white hair. Abdomen smooth, 

 covered with a white pile; the furrows bordering the area on 2^à segment are deep; the 

 basai part straight and oblique, the apical more waved ; they do not unité at the centre of 

 the area, which does not extend to the apex of the segment. The 2"d segment is broader 

 than long, its sides are bordered by a deep, broad furrow which reaches to the apex of the 

 area; the suturiform articulation smooth, curved; its outersides, straight oblique; the segments 

 become gradually narrowed to the apex from the base of the y d ; the apex is bluntly rounded. 

 If any thing the 3 ld joint of the antennae is longer than the 4*. The yà abscissa of radius 

 curved, clearly longer than the basai two united. The 3 rd and following segments of the 

 abdomen are ail broader than long.
