Type. — Greater part of a left hind-wing ; Mr. J. T. Stobbs' Collection. 



Horizon am! Locality. — Peacock marls overlying the Peacock Coal, and near the 

 top of the workable Coal Measures; Foley, near Longton, Staffordshire. 



Specific Characters. — Radial sector dividing in its distal half into fine inwardly 

 directed twigs which end on the distal third of inner margin. Median and cubitus 

 with few widely spaced branches, occupying greater part of inner margin. 

 Anal veins about three to four in number. 



Description. — The specimen has not been available for examination, and my 

 observations are based on the figures published by Woodward and Handlirsch. It 

 is probable that neither of these figures is wholly correct, Handlirsch pointing out 

 what appears to be an obvious error by Woodward in the character of the cubitus

vein, and the position and mode of division of the radial sector being doubtful. 

 Notwithstanding this difficulty, I have by means of an old plaster cast been able 

 to satisfy myself upon the more essential details. 



The fragment is 50 mm. long and 20 mm. wide, and consists of the greater 

 part of a left wing, of which the base and a portion of the basal third are stated 

 to be obscured by a pinnule of Neuropteris. The maximum width is across the 

 anal area, beyond which the wing rapidly narrows owing to the forward direction 

 of its inner margin. The costal vein is marginal and strong, passing in an almost 

 straight line distally until joined by the subcosta, after Avhich it curves gradually 

 backwards into the wing-apex. The subcosta is parallel with the costal margin 

 over more than two-thirds of the wing, and then joins the costa. The base of 

 the radius is not shown in the figures, except a very small portion in front of the 

 point of origin of the radial sector, the latter arising in the basal third of the wing ; 

 beyond the radial sector the radius passes out to the wing-apex, keeping parallel 

 with the costal margin.
