type). 
most of costal area; cross veins between Ri and Rs sigmoidal and 
parallel ; branches of CuA long, extending beyond the level of anas- 
tomosis of Rs with M. 
Holotype: No. 6306, Museum of Comparative Zoology, collected 
by F. M. Carpenter in the lower layer of the Elmo limestone. This 
consists of a nearly complete fore wing, lacking only the apical region. 
The fossil is very well preserved and shows definite indications of 
pigmentation along almost the entire length of R and Ri, the pig- 
mentation broadening out to include surrounding areas after the 
origin of Rs. The precostal area is not entirely known, although 
in the specimen it clearly projects beyond the rest of the wing mar- 
gin ; whether or not it forms as noticeable a biilge as in Parelcana 
cannot be determined. The family assignment of this genus may 
need to be changed when the form of the costa is known.
