 rounded at apices than in the other species; forewiiig heavily 

 clouded with greyish-black upon all the cross-veins and junctions 

 of the veins, as shown in Plate xvi., fig. 3. Hind wing with 

 cross-veins near middle of wing lightly clouded.

Nannochorista is an example of a highly specialised reduced 

 type based upon a very archaic foundation. T am not able to 

 indicate the existence of any close relatives of it at the present 

 day, though it seems highly probable that a careful study of the 

 small Liassic wing-types, such as Orthophlehia, might reveal its 

 ancestry. In order to appreciate the value of Nan^tiochorista to 

 the student of the phylogeny of the Panorpoid Orders, it would 

 be best to deal separately with certain of the archaic and cseno- 

 genetic characters presented by it
