ing immediately into two equal branches, which diverge slightly 

 as they pass to the outer end of the inner wing margin. Traces 

 of two other simple and parallel veins are clearly evident, the 

 innermost either coinciding with the inner wing margin, or being 

 but little removed from it. 



On the evidence and character of the [principal veins, we 

 cannot but regard the specimen as an archaic type of the 

 family FanorpicLc. Regarded as a member of this family, 

 the outermost branch arising from the common root, is the sub- 

 costa, the second the radius, the third the median vein, and 

 the last simple vein is the cubitus. The remaining vein may 

 represent the anal, or be on the wing margin; the evidence is 

 too indefinite to decide. 



In Orthoplilehia couuuunis, Westw. , the sub-costa does not 

 proceed quite so far out before reaching the costal margin as in 

 the Commentry insect, the radial sector has seven twigs in place 

 of five, but occupies the same wing area. The median divides 

 in the middle of the wing, giving off three, possibly four twigs. 

 It is unlikely that the median in the present instance is wholly 

 undivided, its course o\er the free margin of the wing being 

 indistinguishable. The anal veins in Orthophlchia communis 

 are few, and the anal area small. The latter corresponds to 

 that area in the Commentry specimen, which cannot be made 

 out. It is inevitable that a new genus be made to receive this 

 specimen, and to this genus we give the name Sycopteron, with 

 the species name of '^ symmctricaT

Charles Brongniart (Insectes Fossiles des Temps Primaires, 

 p. 388, 1893) created a new genus ''Heeria''' for a group of in- 

 .sects closely related to Stenoclictya, and described a new species, 

 H. Hamyi, of which a wing fragment occurs in the ^lark Stirrup 

 Collection. 



Handlirsch (Die Fossilen Insekten, p. 65) notes that Brong- 

 niart aftervk-ards replaced the name of ''Heeria" by "'Micro- 

 dictya" owing to the former being pre-occupied. (Brong. 

 Insectes P'ossiles des Temps Primaires, 1893, footnote to text 

 description of pi. 39 (23)).
