Genus Labium Brulle.

The genus Lahiutn, though the typical species was described 

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

 Australia. No specimens are in the British Museum from the 

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

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

 liigh elev^ations wdiere little collecting has been done. In the 

 extreme south of Australia and in Tasmania vaiious species of 

 tlie genus are exceedingly common, swarming on the blossom of 

 Leptospermum. It is most remarkable that so little work should 

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

 and tliat nothing should be known of its life-history. Before 

 Brulie defined the genus Erichson had already described a 

 Tasmfinian species as Ichneumon pet itoriiis, but the genus was not 

 again recognised till Canieron described L. ferrugineum in 1901. 

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

 genus is extremely isolated among the Ichneumonidje, the most 

 striking characters being the long exserted labrum, the more or 

 less clavate antennfe, the large ungues and enjpodiunj of the hind
