branch of the cubitus proceeds in its original direction. The pos- 

 terior branch of the cubitus bends at an obtuse angle above the 

 furcation, and fuses dose to the first anal vein, which is gently 

 curved. The second anal vein is slightly sigmoid in curvature. To 

 all appearance this wing was transparent, the veins having opaque 

 borders. 



This fossil is of the greatest interest, since it departs essentially 

 from nil known recetit and extinct ptychopterids, and exhibits very 

 primitive charactere. Thus, the radius with its sector is especially 

 conspicuous, being still at the same stage as is found in the Liassic 

 eoptychopterid EoUmnoUa geinitzi, Handlirsch. Notwithstanding 

 its transient fusion, the media, also, is much more primitive than in 

 the recent genera Ptychoptera and Bittacomorpha; yet not more so 

 than in Macrochih spectrum. Low, from the amber, or in the recent 

 but also very ancient forms, Tanyderus and Protoplasa. The media 

 agrees best with the Liassic Proptychopiera liasina, Ha:ndlirsch. The 

 development of the two anal veins is likewise very primitive.

arises about the middle of the length of the wing, and forms two 

 normal branches. The media bifurcates in the usual way: its an- 

 terior branch is divi'ded, and above the forking it unites with the
