at base, two small spots between tlie antenna?, yellow, all the 

 abdominal segments both dorsally and ventrallj with yellow 

 apical fasciae. Flagellum beneath apically, pronotum and 

 petiole laterally marked with ferruginous. Wings hyaline. 



Head rather broader than thorax^ anterior margin of the 

 prothorax truncate^ scutellum with a shallow longitudinal 

 iurrow, median segment truncate, excavated medially on the 

 dorsal surface, the lateral angles produced to form two spines. 

 Petiole with two small medio-lateral tubercles, slender at 

 base, widening abruptly towards the apex, which is flattened 

 above. 



Head, clypeus, mandibles, and abdomen very finely, thorax 

 rather more coarsely punctured, the area immediately sur- 

 rounding the insertion of the antenn?e, and the surface of tiie 

 truncation of the median segment, shining, impunctate. 



The whole more or less covered with a greyish pubescence, 

 most conspicuous on the vertex and the terminal segments of 

 the abdomen. 



Length IO5 mm.

This species comes very near I. sjyilostoma, Cam., but 

 differs in having all the abdominal segments with apical 

 yellow fasciaj, whereas in /. spilostoma the second segment 

 alone is so coloured.
