half, or a little more, of the costal area, about half of Sc, a little 

 less than half of R, but including the origins of the first two 

 radial sectors, together with a short piece of the basal part of M 

 and a fragment of Cu. The formation of this area is closely 

 similar to that of the type-species, as regards the position of the 

 main veins, but differs from it in the formation of the cioss- 

 veins. In the costal area of iV^. suhcostalis (i.e., between C and 

 Sc), the veins running from Sc to the border are mostly simple,

and never more than once branched. In the present species, 

 they show considerable branching, one of the series preserved 

 sending as many as five veinlets to the costal border. Again, 

 in the area below 8c, the spaces between U and M, and again 

 between M and Cu, are filled, in N. subcostalis, by a close mesh- 

 work of tiny cellules; whereas, in the present species, these aieas 

 are only crossed by a few straight, oblique veins. 



The fragment is beautifully preserved, on a dark greyish- 

 black rock of fairly smooth surface, and bears the label "Glenlee, 

 18.9.92" in pencil in Mr. Mitchell's handwriting.
