nervure; the ist récurrent nervure is received close to the base of the apical fourth of the 

 cellule, the 2 nd near the base of the basai fourth. Antennae slender, shorter than the abdomen, 

 the joints of the flagellum roundly curved, its 2 ai joint distinctly shorter than the 3 rd . rf. 



Length 12 mm. 



Head wider than the thorax, the temples about two-thirds of the length of the eyes, 

 obliquely narrowed, rounded behind. Ocelli in a triangle, placed close together, separated from 

 each other by one third the distance they are from the eyes, in front of the posterior edge 

 of which they are placed. First abdominal segment slender, not quite so long as the following 

 two united ; its base above is furrowed to the spiracles.

 The 2 nd and 3 rd abscissae of the radius are equal in length. The apical joint of the 

 antennae is black, as may be the base of the penultimate. Eyes distinctly converging above, 

 separated there by the length of the 2 nd joint of flagellum. The long spur of the hind tibiae 

 one third of the length of metatarsus. Claws with one distinct tooth near the base. The amount 

 of black on the abdomen varies. Characteristic is the distinct tooth on the apex of the clypeus.

Black, covered densely with silvery pile, a line along the apex of the clypeus ferruginous 

 red, the under side of the antennae — scape and flagellum — the fore knees, apical half of 

 the fore femora, more than the apical half of the middle, the anterior tibiae in front, the 

 middle almost entirely and more or less of the base of the posterior ferruginous ; the palpi 

 for the greater part fuscous, the hair bundle darker coloured. Wings hyaline, a cloud along 

 the transverse basai and transverse médian nervures, broader and more irregular along the 

 outer than along the inner side, one filling the radial cellule from the base to near the apex, the 

 2nd and 3 ld cubital cellules and the 2 discoidal cellules from the front of the i st récurrent nervure 

 to near the 3 rd transverse cubital cellule; the i st récurrent nervure is received shortly beyond the 

 middle, the 2nd near the apex of the basai fourth, the transverse médian nervure is received 

 clearly beyond the transverse basai ; the accessory nervure in hind wings before the cubitus. Q. 



Length 12. m. m. 



Eyes distinctly converging above; the ocelli separated from each other by half the 

 distance they are from the eyes. Apex of clypeus broadly rounded. The 3 rd antennal joint as 

 long as the scape and pedicle united and longer than the 4*. Metanotum weakly irregularly 

 striated from behind the middle. First abdominal segment clearly pedunculated, the peduncle
