borders the inner and outer orbits of the eyes, interrupted at the 

 vertex, antennas longer and more filiform in the $ than in the $ . 

 Thorax, the pro and mesothorax brick red, the scutellum, postscutelluni 

 and the metathorax black clothed with a thin silvery pile, the 

 prothorax and the metathorax in the $ are considerably longer 

 proportionally, than the same parts in the $ ; in both the metathorax 

 is vertically flattened with lateral tubercles, while its posterior face 

 is deeply concave ; wings clear silvery hyaline for one-third of their 

 length from base, the apical portions being dark fuscous with a 

 shining purple effulgence ; legs black with silvery pile, the anterior 

 tibiae smooth, the intermediate and posterior tibia? and tarsi have a 

 few stout scattered spines. Abdomen clothed with a blue black 

 shining pile in the $ : in the £ the 1st and 2nd segments are black 

 w r ith a thin silvery pile, the remaining segments blue as in the $ . 



The above does not quite correspond with Smith's description in 

 the Catalogue of the Hymenoptera, British Museum, which gives the 

 prothorax only as " ferruginous ; " whereas in my specimens the pro 

 and mesothorax are not ferruginous, but, as I call it, a light brick red ; 

 but then the rest of the insect agrees so well with Smith's account 

 of F. fenestrata, that I cannot but think his failure to note the 

 colour of the mesothorax due to an oversight only. 



This species is quite common in Burma in August and September, 

 frequenting low bushes and grass.

 lum and a narrow margin posteriorly on the postscutellum covered
