9 . Nigra ; palpis bi-uuneis ; mandibulis fusco-ferrugiueis, apice 

 nigris ; femoribus tibiisque ferrugiueis ; tarsis calcaribusque fuscis 

 tergitis tribus basalibus fascia obscura apicali albido-sericea ; alis sub- 

 hyalinis, apice late fusco-hyalinis, venis fuscis ; unguiculis in medio

Long. 11 mm. 



9 . Clypeus and face clothed with short silver pubescence ; 

 clypeus short, the anterior margin almost transverse and narrowly 

 depressed. Second joint of flagellum a little longer than the third ; 

 eyes separated on the vertex by a distance equal to the length of the 

 second joint of the flagellum. Pronotum not reaching the level of the 

 mesonotum ; median segment slightly convex on the dorsal surface, 

 opaque, finely and indistinctly transversely striated, much longer than 

 broad, the posterior truncation almost vertical, with a median longi- 

 tudinal sulcus, the sides transversely striated, the striae obsolete in 

 the middle and at the apex, the sides of the segment opaque and 

 smooth, with delicate oblique striae in front. Sixth tergite sub- 

 triangular, the sides distinctly longer than the base, very narrowly 

 rounded at the apex and clothed Avith sparse pale fulvous setae; the 

 surface beneath the setae rather deeply punctured. Comb of the 

 anterior tarsi not very long, the metatarsus with four spines. Inner 

 spine of the hind calcaria equal to three-quarters of the length of the 

 hind metatarsus. Tarsal ungues with a small tooth close to the 

 middle. Second abscissa of the radius very short, not half as long as 

 the third ; radial cell rather narrowly truncate at the apex.

 The distance between the recurrent uervures on the cubitus differs
