Text-fig. 5. Sypharoptera pneuma Handlirsch. Drawing of wings, based 
on holotype, Peabody Museum, Yale University. CuA is strongly convex; 
M is neutral. 
CuA, which is strongly convex, gives rise to M and also to a short 
distal fork; CuP is concave and unbranched. The anal region is not 
preserved in either fore or hind wing. 
Very little of the body structures are actually visible in the fossil. 
Handlirsch’s figure (1911) shows some details which I am unable to 
discern in the specimen, such as the subdivisions of the meso- and 
metathorax and the complete segmentation of the abdomen. At the 
end of the latter there are two very short cerci, consisting of two 
or possibly three segments; these are close together and were ap- 
parently interpreted by Handlirsch as forming a short ovipositor; 
these appendages are very small, only one-half millimeter in length, 
but the segmentation can distinctly be seen. 
The venational pattern is the same in the fore and hind wings of 
Sypharoptera , at least in those parts of the wings which are pre- 
served ; the presence of an additional branch on Rs in one wing must 
be an individual wing variation, for it does not exist in the other 
hind wing of the specimen. The costal area of what appears to be
