Genus Labium Brulie. 

 Labium BruUo, Hist. Nat. Insect. Hymen, iv. p. 316 (1846). 

 The genus Labmm, though the typical species was described 

 from ISew Guinea, is really characteristic of the southern half of 

 Australia. No specimens axe in the British Museum fi-om the 

 northern half of Australia, and we may certainly assume that the 

 genus does not occur in the north-eastern coast regions, unless at 

 high elevations where little collecting has been done. In the 

 extreme south of Australia and in Tasmania various species of 

 the genus are exceedingly common, swarming on the blossom of 

 Leptospermum. It is most I'emarkable that so little work should 

 have been done on a genus so conspicuous and so plentiful as this, 

 and that nothing should be known of its life-iiistory. Before 

 Rrulle defined the genus Erichson had already described a 

 Tasuianian species as Ichneiomon jMitorius^ but the genus was not 

 again recognised till Cameron described L. ferrugineuin in 1901, 

 Morley later (1915) adding another species, L. clavicorne. The 

 genus is extremely isolated among the Ichneumonidte, the most 

 striking characters being the long exserted labrum, the more or 

 less clavate antennfe, the large ungues and enjpodium of the hiiid
