 the scutellum and frenum, brick-red ; the abdomen apically badious 

 with its apex, the palpi and a central flagellar band, white. Head 

 deeply punctate and not posteriorly constricted ; f roiis strongly 

 excavate, with a central fusiform and glabrous horn above the laterally 

 subelevated scrobes ; facial orbits pale-marked ; face and clypeus dull 

 and closely punctate, the latter strongly transverse and apically 

 truncate ; labrum exserted, mandibles stout with subequal teeth, 

 cheeks not short. Antennae stout, with the scape and elongate basal 

 flagellar joints badious. Thorax cylindrical, somewhat scabrously 

 punctate with the sternum, base of mesopleurae and whole metathorax 

 black ; notauli and sternauli deeply impressed, the latter short ; both 

 the metaiiotal transcarinae strong and entire, basal area weak and 

 subquadrate, apophyses small and acute, spiracles distinctly longer 

 than broad. Scutellum sparsely punctate and not dull. Abdomen 

 elongate fusiform and black, becoming indefinitely dark castaneous 

 from apex of the large second segment which is hardly longer than 

 apically broad, with its apex callose ; seventh segment entirely white ; 

 basal segment elongate, but little explanate apically and glabrous with 

 a central subapical sulcus only ; remainder finely and closely punctate, 

 with obsolete thyridii ; terebra straight, stout and longer than half

 tibiae and tarsi fulvidous, and hind calcaria paler. Wings fulvescent 

 hyaline, stigma and nervures castaneous ; lower basal a little ante- 

 f urcal ; discoidal nervure nearly straight and strongly divergent from 

 the anal, which forms a subobtuse angle with the broadly fenestrate

 and a little broader than high areolet ; radial nervure apically strongly 

 reflexed ; nervellus opposite and intercepted very slightly below its 

 centre. Length, 11 mm.
