tip of i?i. In this case Ri is quite short, extending only a slight 

 distance beyond the fork of the radial sector, and the cross-vein r 

 is very long and simulates a section of vein R, ending at the outer 

 part of the stigma; according to this interpretation, Ri would be 

 separate, but usually very indistinct or lacking, /?•> is atrophied at 

 its tip except in two species of Phalacrocera (revlicata and neoxena)^ 

 whereas the vein hitherto considered as being Ri+2+3 is really R3 

 alone. This latter explanation of these veins of the radial field is 

 probably the correct one.

 with Longurio testaceus Loew, the genotype, in some respects. L.
