thorax hardly duller ; propodeon much duller generally, owing to the 
raising of the reticulation, but with scattered points of light from the 
bottom of the cells. Wings hyaline, veins decidedly brownish. Legs 
coxa and femora (except apex in hind legs, more broadly in mid and fore 
pairs) metallic blue black : apices and tibiae brownish yellow ; first 
two tarsal j oints paler still ; third a little darker ; fourth brown. 
In T. spirabilis the (J is duller than tachos and practically non-metallic ; 
(this may be due partly to preservation in spirit) veins paler. Legs 
brownish black, non-metallic ; hind femora concolorous ; mid and fore 
femora narrowly and obscurely paler at the apex ; hind tibiae pale smoky ; 
hind tarsi, fore and mid tibiae and tarsi very pale, claws darker. In the $ 
the scape of the antennae is pale ; hind tibiae paler than in the (J, and the 
femora of a lighter brown. The $ of tachos is imknown. 
Besides the colour differences the species may be separated by the 
propodeon (figs. 22, 23). In tachos the spiracle is small and the central keel 
longer than the middle of the post-scutellum, while the diameters of the 
area bounded by the forked extremities of the lateral keels intersect at 
right angles. In tachos also there are eight short bristles fringing the 
scapal sense organ, and the joint itself is narrower.
