 coarsely aciculated, the lower closely obliquely striated. 

 Mesopleune closely and somewhat strongly punctured and 

 covered thickly with white pubescence. Metapleurae strongly 

 obliquely striated, the strise becoming more widely separated 

 towards the apex. jMesosternura punctured, irregularly and 

 widely furrowed in the middle. The alar uervures are 

 fuscous ; the second transverse cubital nervure is united to 

 the radius at the foot of the apical abscissa, which is thick- 

 ened above the junction. Abdomen shining, obsoletely 

 punctured; the apical segments are thickly covered with pale 

 fuscous pubescence ; the base of the underside of the petiole 

 has a distinct tooth, which is broadly rounded at the base ; 

 tlie apex is straight and oblique, from it a keel extends to the 

 middle. The apices of the ventral segments are fringed with 

 long dark fuscous hair. Legs entirely black except the lower 

 side of the fore tibife; the hair is thick and white; the 

 calcaria and the tarsal spines are pale rufous. 



The transverse median nervure is placed shortly behind 

 the transverse basal.

Black, the four posterior trochanters, femora, and tibi?e 

 red; the wings fuscous violaceous; the median segment with 

 two keels, which unite before the top of the apical slope^ the 

 apex of the segment reticulated. 



Long. 18-19 mm. 



Flagellum of antennae fuscous beneath, the scape covered 

 •with white hair. Front and vertex rugosely coarsely punc- 

 tured, the punctures running into reticulations above the 

 antenna3. Mandibles black, dull piceous beyond the middle. 

 The basal part of the pronotum coarsely aciculated, smooth 

 and shining on the apex, and thickly covered with short 

 white hair; the apical part coarsely closely punctured^ its 

 basal slope smooth. The base of the mesonotum smooth, 

 impunctate, the apical part with large deep punctures. 

 Scutellura with large, deep, irregular, elongated punctures, 

 all clearly separated ; the postscutellum minutely punctured, 

 but not closely. The basal half of the basal part of the 

 median segment closely rugosely punctured, the apical reticu- 

 lated, puucturcd ; the apical slo})e bears shallow round punc- 

 tures, which are sparser in the centre; on the basal part are 

 two keels, which unite before the top of the apical slope. Pro- 

 pleuras strongly punctured at the base, the middle smooth, 

 the apex closely finely striated, the striie becoming weaker at
