A second specimen of this species, also in an ironstone concretion 
from the Francis Creek Shale, was collected in 1971, by Mr. Paul 
Tidd of Mendota, Illinois, in Pit Eleven and is now contained in 
Mr. Tidd’s collection (figure 7) It consists of the basal part of a 
fore wing, portions of the head and thorax and traces of a hind 
wing. Determination of the species is based on the fore wing; except 
for minor points, such as a deeper fork on CuP, the venation is like 
that of the holotype. The wing markings, characteristic of the spe- 
cies, are faintly preserved. Some of the thoracic structures are of 
interest, since they are known in only a few genera of the order. 
The thoracic segments are unequal (figure 8) the prothorax being 
slightly the smallest of them. There are no indications of the 
prothoracic lobes, which have previously been described in Homa- 
loneura (Kukalova, 1969). The fore legs are preserved in the ob- 
verse half of the specimen; they are robust and possess numerous
