Urapteetx, Leach. (Plate IX. figs. 1, 2.) 



This genus requires breaking up, the neuration of the ty[)ical 

 group being as follows : — Primaries with the costal vein rather 

 short, terminating at a little beyond the middle of the margin ; 

 discoidal cell extending to the middle of the wing or shorter, the 

 subcostal four-branched, the first branch emitted before but close 

 to the end of the cell, united to tlie costal and separated after a 

 considerable interval ; the three others forking from a long foot- 

 stalk beyond the cell ; upper radial emitted from the anterior 

 angle of the cell, lower radial dividing the discocellulars unequally, 

 the lower being decidedly longer than the upper; both disco- 

 cellulars are transverse and concave ; second and third median 

 branches emitted together from the end of the cell and far 

 distant from the first branch; submedian vein extending to 

 external angle : secondaries with the costal and subcostal veins 

 closely approximated for some dit^tance from their origin and 

 then somewhat abruptly separating ; the subcostal two-branched, 

 the first branch emitted just before the end of the cell, the 

 second from the anterior angle, where it represents the radial of 

 some Moths ; discocellular oblique and concave ; other veins as 

 in the primaries. In this genus the primaries are triangular, 

 the secondaries irregularly angulated, and with a longer or 

 shorter tail at the extremity of the third median branch *.

* Some authorities, I believe, are inclined to the opinion of there being a 

 close relationship between TJra'pteryx and Asthenia. I believe this view to be 

 wholly erroneous, but in this place will not attempt to discuss the question.
