■i or 5 straight and simple cross veins. The 5 (in the anterior 

 wing) or 4 (in the posterior wing) simple branches of the 

 sector run obliquely to the oblique apical margin and are 

 united by a few straight cross veins. The media is reduced to 

 a simple independent vein and likewise the cubitus, which has 

 hut a short strongly diverging branch near its apex. The first 

 anal vein is moderately straight and apparently sends 2 

 branches backward. All the main veins are united by isolated 

 and widely spread cross veins. There is no doubt that the 

 wings were of a delicate membranous texture. 



This fossil somewhat resembles certain Megasecoptera, but 

 lacks certain characteristics of this order, such as the tempo- 

 rary fusion of cubitus, media and radius, the shortened subcosta 

 and the position of the wing being also quite different ; further, 

 an ovipositor has never been found in the Megasecoptera. 

 The want of intercalary veins and the strongly reduced media 

 and cubitus do not allow this fossil to be put among the 

 Ephemeroidea.
