Art. X.] Hine, Panorpidae of America North of Mexico. 259 
Anterior wing 18 mm., length of body 17 mm. Yellowish; 
posterior femora with small black spots, wings yellowish, basal 
half with a few black spots, cross veins margined with fuscous. 
Male appendages, from side view, not protruding beyond 
the abdomen, widest on basal half, apical part slightly narrower. 
This species is easily known by the black spots on the 
femora and basal half of wing. 
I procured specimens in the District of Columbia at 
intervals between June 25 and Aug. ist, 1897, and again at 
the same place in 1899. 
The specimens of this species that I saw, always remained 
close to the ground. If disturbed they never ventured above the 
herbage in which they were hiding, but flew a short distance 
through the foliage, and came to rest again near the surface.
