;i nearl}' straig-ht fold. C^^stal area with o])li(iue cros.s veins. The 

 remaining V)road area.s have a wide-meshed networl^; the small ones 

 have cross and intercalary veins. From the distal end of the radius 

 olilique veins stretch to the anterior margin.

MICROBLATTINA Scudder. 



SiilK'osta reduced. Radius Avitli a numlier of lu'anches directed to 

 the costal margin. Radial sector with about 6 offshoots 1)ran('hing otf 

 backward. Media with 2 furcate branches. Cubitus with several 

 oblique veinlets extending backward. Of intercalary and cross-veins 

 there is nothing to be seen.

 JIolotype.—OAt. No. 88098, U.S.N.M. 



Family .l^]THOPHLEBID.Fv, new family. 



In this family, which I regard as a provisional one, I place a form 

 whose relations to the oryctoblattids can hardly be misunderstood. 



The costal area is broad. The subcosta sends out numerous obliijue 

 veins to the slightly curved costal margin. The radial sector issues 

 from the radius not far above the middle of the wing and sends out 

 several (3 or -i) branches to the apical- border. The media separates 

 into 1 superior furcate, and 1 inferior copiously-branched ott'shoot. 

 The cubitus sends out 4 or 5 oblique branches to the inner border. 

 Anal area long and narrow, marked off by a gentl3'-curved vein. The 

 larger interspaces are bridged over by cross veins far removed from 

 each other.

Loeality. — Mazon Creek, near Morris, Illinois. Pennsylvanian;

Length of wing, 38 mm. 



Scudder referred this fossil to the Palaeopterina, a group of neurop- 

 teroid pala^odictyopteres. According to my view, it can scarcely' l)e 

 dou))ted that the specimen pertains to a form of the blattoid series.
