Art. X.] Hine, Panorpidae of America North of Mexico, 247 
the form that I have identified as niiptialis averages nearly ten 
millimeters larger ; and of more than twenty specimens before 
me none have the pterostigmal band forked behind. 
Panorpa maculosa Hagen. 
Plate LIX, Fig. 6. 
Panorpa maculosa, Hagen, Neuropt. N. A. 245. 
Anterior wing 11-13 mm. Wings hyaline, maculate with 
numerous small, brown, irregular spots ; nearly all the cross 
veins more or less bordered with brown, first vein uniting with 
costa near the middle of the wing — far before the pterostigma. 
The wing markings in this species are somewhat variable. 
Some specimens have quite distinct spots, while in others the 
brown is confined almost entirely to the margins of the 
cross veins. 
Hagen’s types, a male and a female, are in the Museum 
of Comparative Zoology at Cambridge.

4-191; Walker, Cat. 464; Hagen, Neurop. N. A. 243. 
Anterior wing ii— 13 mm. It is hardly worth while to give 
a full description of this species ; it has the appearance of ma- 
culosa and the wing markings pass through the same variations 
as in that species. The difference which I mentioned in the 
key, namely; in nebulosa the sub-costa reaches the pterostigma, 
while in mactdosa in ends near the middle of the wing, is the 
only distinctive character I offer.
