sometimes complete, sometimes present only in the distal half of the basal cell. The 

 seventh funicular segment (detached first segment of the clava) is 1-6-1-7 times 

 as long as broad, usually as long as the sixth segment though occasionally very 

 slightly shorter. The propodeum has its median carina relatively strong and 

 straight, most often complete though sometimes extending only half way to the 

 hind margin (occasionally it is slightly irregular) ; the costula is usually distinct but 

 very weak in one specimen ; the plicae are strong and extend nearly to the spiracles. 

 The costula usually intercepts the median carina at (though sometimes before) its 

 middle. The anterior transverse crest of the gastral petiole is usually sharp, 

 occasionally weak. Males presumed to be conspecific with these females have the 

 antennal scape strongly dilated above the middle, where there is a shiny boss which 

 extends more than half way down the external surface ; they have the funicular 

 segments rather longer than those figured by Delucchi (1955, fig. 25) for the male of 

 glaucum. Most of these specimens have 4 teeth in both mandibles (one female, 

 which does not appear to differ in other respects, has only 3 teeth in the left 

 mandible) .

I have not seen any fresh material which completely fits Delucchi's description of 

 glaucum. In his key (1955 : 21-22) he distinguished the female from that of 

 novickyi as follows : cubital vein bare on both surfaces of the fore wing ; seventh 

 funicular segment (detached first segment of clava) hardly longer than broad and 

 shorter than the sixth segment ; propodeum without a costula, its surface reticulate. 

 As regards the propodeum, he contradicted the above statement in his description 

 of the female (ibid. : 28) in which he stated that each plica was connected to the 

 median carina by a costula or a complex of small costulae. I have a female from 

 Scotland in which the antennae agree fairly well with Delucchi's description and 

 figure, having the seventh funicular segment only slightly longer than broad ; but 

 this specimen does not agree completely with the description of glaucum as regards 

 the cubital vein and the propodeum. Possibly it is an aberrant specimen of 

 novickyi.
