the extreme tip and base only wanting. It may be called Blattina 

 fascigem from the grouping of most of the principal nervules into 

 bundles, although this feature is not very conspicuous. The anal 

 vein is very deeply impressed; the marginal area is very broad and 

 in its basal half almost entirely devoid of cross veins; the entire 

 margin of the apical half of the wing is broken by nearly straijjht 

 and equidistant cross veins over a large area, while the disc of the 

 wing is irregularly reticulated. The costal margin is very broadly 

 and gently convex, and the inner margin nearly straight, so that the 

 wing is of nearly equal breadth throughout. Its length (with broken 

 tip) Is 35 mm.; probably it was about 38 mm. long; its breadth is 

 15.5 mm. The species seems to be somewhat nearly allied to Blat- 

 tina primceva Gold, of the European carboniferous formation, but 

 differs distinctly in the extreme weakness of the scapular vein, its 

 nearly uniform distance from the margin throughout its course, and 

 its continuation nearly to the tip of the wing. 



A full description and figure of the sjiecies will be given in a fu- 

 ture paper.
