tionship or similarity with the Chalcididae is evidently wrong. It is 
doubtful if Kieffer actually saw any specimens. 
In 1959 Szabo established a new tribe within the Platygasteridae, 
the Amitini, to comprise the following genera: Amitus Hald., Fidiobia 
Ashm., Pulchrisolia Szabo and Isolia Forst. The genus Sceliotrachelus 
Brues exhibits a striking relationship with some of these genera (par- 
ticularly with Isolia Forst.) so we are sure it should belong there. 
From the nomenclatorial point of view we are forced to change the 
name of the tribe as follows: 
Sceliotrachelini Brues, 1908 — new status 
(= Amitini Szabo, 1959 — new synonymy) 
As Sceliotrachelini Brues was proposed originally as a subfamily of 
Scelionidae in 1908 it becomes automatically the new name of the 
group. The type genus is consequently Sceliotrachelus Brues. 
The tribe Sceliotrachelini, according to our conception, should be- 
long to the subfamily Inostemminae. We suggest it to be the most 
apomorphous tribe of Inostemminae, where the subcostal vein is 
tending to disappear gradually. In Fidiobia Ashm. (in all species we 
have seen, except in brachypterous F. pronotata Szabo) there is a 
very short subcostal vein, knobbed apically. In Platygastoides Dodd, 
at least in P. mirabilis (the type of genus) the subcostal vein is still 
knobbed apically, but as a whole, the vein is tending to disappear 
(Fig. 2). In Amitus Hald. ( = Zacrita Forst., Passalida Breth.) 
there is sometimes a trace of vein but this is never knobbed apically. 
In Isolia Forst. and Sceliotrachelus Brues the fore wing is perfectly 
veinless. The typical character of Sceliotrachelini is the antennal 
club in the female, which is abrupt, massive and 3-jointed (in Amitus 
Hald. the club is rather solid, the sutures obsolete) . The gaster in 
this tribe is very stout, resembling that of the subfamily Telenominae 
(Scelionidae), not carinated ventrally (there is no impressed sub- 
marginal ridge) at most slightly sharpened at sides. 
The curious Platygastoides Dodd is included also in this tribe. 
It combines some characters of Fidiobia Ashm. and Isolia Forst. 
Figures 2, 3 and 4 illustrate this peculiar insect.
