The narrow wing and peculiar prominence on the forceps 
of the male, serve to identify it readily. 
Fanorpa americana Swederus.

Handl. 8-279; Westwood, Trans. Ent. Soc. of London 4-189 ; 
Hagen, Neuropt. N. A. 242. 
Panorpa fasciata, Fabricius, Ent. Sys. 2-98; Klug (in part), 
Mon. Panorp. 105. 
Anterior wing 12 mm. Body brown ; wings yellowish ; 
an elongate, basal spot, an oblique band before the middle, a 
dorsal spot, a pterostigmal band, and apex black. The wing 
bands are straighter, and much more regular than in any other 
American species except perhaps niiptialis. The form of the 
wing is striking, being broad and rounded at the apex as shown 
in the figure. The 6th abdominal segment of the male bears 
a short horn.

Panorpa fasciata, Klug (in part) Mon. Panorp. 105. 
Anterior wing 11-13 mm. Wings yellow, a basal spot, a 
band before the middle rarely interrupted, a costal spot, a ptero- 
stigmal band widened before, and apex black. Horn on 6th 
abdominal segment of the male, 7th segment ob-conical increas- 
ing gradually in size from near the base, 8th segment usually 
shorter than the 7th. 
This species is easily separated from americana by the nar- 
rower wings with irregular bands, and from the confusa group 
by the form of the 7th abdominal segment, and also in nearly 
always having three complete bands on wings.
