 Terebra as long as body, sheaths black, with yellowish snbapical 

 band. Hind coxfe trans-striate ; hind femora bidentate. 



Black ; head flavo-ferruginous, frons and vertex darker ; basal 

 half of second segment rufescent ; anterior coxse and legs, hind 

 tibife and tarsi ferruginous, femoral teeth rufescent. Wings 

 hyaline, stigma very long and narrowish, brown ; nervures dark 

 brown. 



Length IGg mm. ; petiole 5-4 mm. ; terebra 16^ mm. ; fore 

 wing 9 mm. 



Habitat : Sumba, Malay Archipelago. 1 2 ; Grelak. Type at 

 Stettin. 



Differs from F. indicus in the sculpture of prothorax, shorter 

 terebra, and colour. The femoral teeth are rufescent, whereas in 

 F. indicus they are black (Enderlein), or white (Schlett.); the 

 black apex of terebral sheaths is more than half as broad as the 

 pale subapical band in sumhanus, but very much less in indicus.

5 6 . Frons rather finely and irregularly transrugose, the 

 ridges outwardly forked ; occiput more finely rugose, with indis- 

 tinct longitudinal median impression. Pronotum transrugose, 

 more densely towards base, and intermixed with coarse punctures, 

 lateral margins smooth, a broad posterior margin polished smooth 

 and in front of it two roundish lateral spaces very finely and 

 densely striate, having a velvety appearance, posterior angles 

 strongly rugose. Scutellum polished smooth, laterally sparsely 

 punctate. Mesopleurte rather closely pimctate, posterior margin 

 very finely punctate and sparsely yellow pubescent. Petiole finely 

 and densely trans-striate ; second segment basally smooth and 

 shining, apical half dull. Terebra in $ much longer than body, 

 sheaths black, with a broad yellow band before apex. No details 

 as to the hind legs are given.
