This subfamily is also treated somewhat differently from Forster 

 and Marshall, since I have included as components of it oroups placed 

 elsewhere l)y these authors — th(^ so-called Cali/j)tiri<p and the o(>iuis 

 Org'dvx Halida}", the latter having- heretofore been considered a 

 component of the A<jathid'ni<y. 



Both, however, have very little affinity with the AgatJddinw, and 

 ar(^ in every way much more ck)sely allied to the IlelconincB^ from 

 wliich they are separated ])y having- oidy tii-o cubital cells in the front 

 wings; otherwise they are identical.
