Genus NEORINOPIS BUTLER. 

 Neorinopis Butler, I.cpid. Exot., i, 127 (1873) ; Ib., Geol. Mag. x, 3. 



IN the shape of the wings (PI. I, fig. 8) this genus closely resembles Neorina 

 (PI. II, fig. 13). The fore wings are arched and roundly produced at the apex, 

 though not so strongly as in Neorina, rather as in Antirrhsea or Coalites, the costal 

 margin is regularly, but not, as in Neorina, very strongly arched, and the apex is 

 well rounded ; the outer border is sinuous and scarcely crenulate, the upper por- 

 tion, above the middle of the subcosto-median interspace, very strongly convex 

 and particularly prominent at the tip of the second inferior subcostal nervule; 

 below, the margin is again convex, starting from the middle of the upper median 

 interspace ; at first (over one interspace) gently, afterward more fully, but still 

 rather broadly, to the well rounded lower angle; the inner margin is slightly 

 concave. The hind wings resemble those of Neorina far more than those of 

 any other genus, but are long and proportionally rather more produced than in 

 Ncorina, with less crenation of the outer border, and a shorter and slenderer 

 tail; the costal margin is strongly and abruptly convex next the base, but beyond 

 this passes with a regular and gentle convexity to the outer angle, which is 

 larger than a right angle and somewhat rounded off; above the tail the general 

 trend of the outer border forms scarcely more than a right angle with the gen- 

 eral course of the costal margin and is gently crenate; the tail, which lengthens 

 the upper median nervule by about one-fourth, is about the width of an interspace 

 at the base and tapers to a rounded point, at first rapidly, afterward slightly; the
