C. The radial cross-vein in the front wings with its caudal 
end basad of R,, or if it or R, is absent or they are 
opposite then the anterior tibix have a single apical 
spur. 
D. Front wings with M, complete; ovipositor more or 
less saw-like, usually exserted and with promi- 
nent sheaths; antenne not inserted beneath a 
frontal ridge. 
E. Anterior tibie each with only one apical 
spur; propodeum divided longitudinally. 
F. Pronotum presenting a strictly cephalic 
surface, or both cephalic and dorsal 
surfaces; front wings with the me- 
dio-cubital cross-vein subequal in 
length to the transverse part of 
media. (Fig. 6.) 
G. Pronotum transversely righ t- 
angled, so that it presents both 
a strictly dorsal and a cephalic 
aspect, the latter concave; 
mesoprescutum poorly defined

GG. Pronotum a narrow collar ex- 
tending around the front of 
the thorax, therefore present- 
ing lateral and cephalic but no 
dorsal aspect; mesoprescutum 
well developed; Se, present in 
the front wings as a transverse 
vein; maxillary palpi four- 
segmented; labial palpi three- 
segmented, the first segment 
elongate. XIPHYDRIIDH 
FF. Pronotum more or less quadrate, not 
transversely angled, presenting lat- 
eral and dorsal but no_ strictly 
cephalic surfaces, its posterior mar- 
gin extending almost directly from
