Face with a heavy facial carina extending from epistome to lunula between the 
antennae and convex, bulbous or flattened on much or all of its anterior surface 
(Text-fig. 12). Eyes bare. [Parasites of Coleoptera] . PROSENINAE (part) (p. 41) 
Face without such a facial carina, usually flat or sunken, if weakly carinate just 
below antennal bases (Macrochloria) then eyes haired, if bullate between antennal 
bases only (Alophora) then cell R; long-petiolate (but sharp ridge-like facial carina 
on whole face present in Eutherini) . : : : 3 
One supra-alar seta (Text-fig. 54). Pre-alar se Bee (eae Saale. Usually 
one post ia seta or none. Head often holoptic or almost so and upper eye facets 
often conspicuously enlarged. Eyes always bare : 4 
Two or more supra-alar setae (Text-figs 56-63) (hindmost sss wea sercae 
may be absent in Minthoini). Pre-alar seta almost always present (sometimes 
hairlike). Normally two or three post ia setae. Head never fully holoptic and 
eye facets never greatly enlarged. Eyes bare or haired . : : : : 5 
Lower calypter very broad, straight or concave on its hind margin. Prosternum 
bare. Labellae without palpiform processes. Not more than one fost ia seta. 
[Parasites of Hemiptera] . . PHASIINAE (part) (p. 29) 
Lower calypter subcircular posteriorly and ‘strongly diverging from the scutellum. 
Prosternum on each side with a long seta directed downwards. Labellae usually 
with a distinct pair of palpiform processes. Normally two post ia setae. ([Para- 
sites of Coleoptera) . ; : Palpostomatini (Tachininae, part) (p. 53) 
Two post ia setae present standing widely apart from each other with the anterior 
one not far from the transverse suture, the setae either subequal in size or the 
antevioy one enormous and much stronger than the posterior one (Text-figs 56 & 58). 
Either the hind coxae very widely separated from the abdominal base by a deep 
completely sclerotized bridge, or apex of 2 abdomen with forceps-like processes, 
or both. Postabdomen usually strongly recurved under the preabdomen. Wing 
with cell R, closed and long-petiolate (Text-figs 76 & 78). [Parasites of Hemiptera] 
PHASIINAE (part) (p. 29) 
Two or more (usually three) post ia setae present which increase in size towards the 
hindmost (Text-figs 57,59-63), if only two are present then the anterior one far 
from the transverse suture (except in Parerigonini and in Minthoxia in which two 
widely spaced subequally strong post ia setae present, but then other characters 
not fitting). Hind coxae and abdominal base not very remote from each other, 
area between them membranous medially; end of 2 abdomen never forcipate. 
Postabdomen not distinctly recurved under preabdomen. Wing with cell R; 
usually open, a few exceptions (e.g. Euthera). [Not parasites of Hemiptera, except 
probably Eutherini| : F . 6 
Wings with a pattern of eee eee black panes (est fig. a5) Celle 
with long petiole (Text-fig. 77). Face with a very prominent sharp median ridge 
up its whole height (Text fe 24). Antennae exceptionally long, their apices 
reaching beyond the epistomal margin. [Probably parasites of Hemiptera, no 
Australian records | F Eutherini (Phasiinae, part) (p. 39) 
Wings without any bold nae pattern. Cell R, usually open. Face without a 
sharp median ridge up its whole height (if trace of a sharp ridge ventrally then 
this swelling dorsally). Antennae of varied length but not exceeding the epistomal 
margin. [Not parasites of Hemiptera) 
Forms with the following characters present Sirmultaneously- eyes bares anteatee 
short and antennal axis at or below level of eye middle (Text-figs 29-30); gena 
broad, at least as wide as length of third antennal segment and often almost as 
wide as antennal length (Text-figs 29-30); no definite reclinate orbital setae; 
rows of frontal setae descending to level of lunula or only just beyond; prosternum 
bare; pra seta small; scutellum with three pairs of marginal setae (basals, subapicals 
and strong crossed horizontal apicals, Text-fig. 70) (rarely some supernumeraries
