but in all of these the wing base is distinctly petiolate, as shown in 
Handlirsch’s figures (1919). In his diagrammatic representation of 
the wing, Bolton (1921) shows a subpetiolate condition, in which 
the wing narrows rather more gradually than depicted in Handlirsch’s 
figures. Although there is probably some slight variation in the de- 
gree of petiolation of the wing, I believe that Handlirsch’s figures are 
more nearly correct in respect to this part of the insect. One of the 
two specimens in the Scudder collection at the Museum of Compara- 
tive Zoology shows the petiole distinctly (Plate 11). It is possible, 
of course, that the fore and hind wings differed in the degree of
