Fore wing: length of preserved part of wing, 80 mm; its maximum 
width, 38 mm. The species differs from pennsylvanicus by its larger 
size and by the structure of the anal area. It is about twice the size of 
pennsylvanicus, and the first anal vein (1 A), at least the basal half of 
it, has no major branch. 
Type: No. 11028, (K6757) William Penn Memorial Museum, 
Harrisburg; collected by W.F. Klose II in a strip mine 400 meters 
east of bench mark 1271 on the St. Clair-Mahanoy City Road, 
Blythe township, Schuykil County, Pennsylvania; Allegheny Series; 
underclay Buck Mt. #5 coal. The specimen consists of the basal two- 
fifths of a fore wing; parts of the wing, especially the anal area, are 
clearly preserved, but some veins, as RS and CUP are very faint and 
uncertain. However, the convexities and concavities of the veins are 
clear and the homologies of the veins are obvious. 
The most distinctive feature of the wing is the absence, in the 
preserved part, of a major branch of 1A. In all other Protodonata 
known to me, 1A gives rise (at about the level of the peak of the 
curve in CUP) to a prominent branch, which in turn forms a series 
of simple branches leading to the hind margin of the wing. This 
insect was obviously larger than pennsylvanicus, the wing of which 
has been estimated to be 55 mm long (Carpenter, 1960). Compari-
