the slender tacies, stout head, coarse thoracic sculpture, slender 

 antennae, and narrow wings, with the more salient features, such 

 as the distinctly broadened hind tarsi, apically produced meta- 

 thorax and the entire lack of all trace of an areolet, which is 

 emphasised by the external cubital nervure extending straight 

 from the second recurrent nervure to the apex of the wing. 



Compared A\ith the present condition of the other tribes, we 

 may consider this group, as it now stands, as fairly representative, 

 probably on account of the large size and conspicuous coloration of 

 the majority of its species, though doubtless the following is but 

 a titlie of those that remain to be discovered.
