(. Itufa; capite flavo, antennis nigris; abdomine, larsis inter- 

 mediis articulis tribus apicalibus, tibiisque fcarsisque posticis nigris; 

 tergitis •'! 8 apice angustissime all>o-marginatis; sternitis albidis, 

 utrinquc nigromaculatis"; alia pallide fuscis; stigmate venisque fuscis. 



Long. 11 mm.; terebrae long. 45 mm. 

 . Head i'. it her large, not narrowed behind the eyes ; face minutely 

 and closely punctured, a narrow groove reaching from between the 

 antennae to the anterior ocellus. Scape twice as long as broad; 

 antennae distinctly longer than the whole insect, measuring about 

 I.'! mm. Vertex and thorax smooth and shining, the parapsidal 

 furrows almost obsolete. Median segment sparsely and minutely 

 punctured; abdomen smooth and shining; second tergite with a 

 large triangular basal area, which nearly reaches the apical margin, 

 the marginal grooves of 1 he basal area smooth; the anterior angles 

 of the second tergite hounded by a smooth groove which runs from 

 the basal angles of the triangular area to beyond the middle of the 

 lateral margin of the tergite; second suture broad and finely crenu- 

 late in the middle, narrow and smooth at the sides. Anterior 

 angles of the third tergite huge, the grooves bounding them reaching 

 1 1 > the middle of the lateral margin of the segment, hut not to the 

 middle of the hasal margin. first abscissa of the cubitus sharply 

 bent at aboul one-third from the base, recurrent neruire received 

 by (he lirst cubital cell a little before the apex; nervulus not quite 

 interstitial, received just beyond the basal nervine.

 L901; Mackay {Turner), October 1899. 



I took three specimens at the same time at Kuranda, 

 flying round a fallen log in dense jungle. The iMaekav 

 specimen is smaller measuring 10 nun., terebra 27 mm., 

 laii I think it belongs to the same species. 



This seems to belong to the group of /. marginatus, Szep
