yellow, pubescence generally whitish but yellowish at apex of abdomen. 
Wings very faintly embrowned. Legs, all tarsi pale with a faint reddish 
tinge especially distally. Fore femora up to |, mid femora up to | 
from base nearly black, thereafter brownish and yellow at the extreme 
tip. Fore tibia yellowish or yellowish brown with a darker spot towards 
the middle externally ; mid tibia, blackish brown, paler at base and 
more broadly at apex. Hind femur ferruginous with a dark spot ex- 
ternally towards the base and paler at the extreme apex ventrally in 
front of the in.sertion of the tibia. This pale spot does not nearly reach 
the edge dorsally and its limits are indefinite. Femoral teeth black 
(ftg. 2J). 
The hind tibia is mainly concolorous with the femur, but the apical 
J is yellowish white and the ventral edge blackish. 
Head of the ‘ minula ’ type with stout antennse. Between and below 
the toruli the surface to the clypeus is entirely smooth but without 
lateral ridges or keels. Mandibles both bidentate, apically contracted, 
the teeth short and rounded, scutellar plate well developed and broadly 
incised in the middle. No prominence or tooth dorsally behind the spiracle 
on propodeon, no tooth on hind coxa. Hind femur externally with strong 
not very closely set punctuations. No basal tubercle on inner aspect. 
Teeth 10 in number, the first at about -J from the base, large, followed 
by two smaller, the next five are subequal to the first. The first 6 
teeth are widely spaced (fig 2, /). Abdomen, Isttergite entirely smooth 
and polished, 2nd with numerous punctures at the sides but reduced 
across the middle to a single row. Distally this tergite is dimmed and 
roughened the surface being raised into many very minute chitinous 
points. Succeeding tergites smooth basally but with transverse rows 
of strong pimctm’es apically. Length barely 6 mm.. Alar expanse 
12 mm.

1915. 
This species belongs to the ‘ Jonscolomhei ’ section of the ‘ minula ’ 
group. In 0. fonscolombci Dufour (Ann. Soc. Ent. France X, p. 16, 
1841) there is an incipient tooth behind the spiracle at the side and a well 
developed basal tubercle on the inner aspect of the hind femur. As 
regards colour the tegulse in the European species are entirely yellow, 
the hind coxae piceous or black at the base and more ferruginous towards 
the tip. The yellowish apical spot on the hind femur reaches the dorsal 
edge and there are two yellow bands (one sub-basal, the other apical) 
on the hind tibia. There is also generally but not invariably a pale 
anterior (ventral) median spot on the scape.
