minute segments are present at the apex in such species as I 
have had sufficient material-to break up. Banks founded his 
genus Worcesteria on the presence of these small apical segments, 
of which in his species two occur. It is thus evident that Banks’ 
genus must sink, unless we divide Toxorhynchites up into several 
genera on the single character of the number of these minute 
terminal segments, which lie completely hidden in scales, and 
which can only be found by careful dissection. Moreover, we 
should have such closely allied species as gilesii and immisericors 
in separate genera if we did so.
