Holotype ( $ ) : Rector, Penna., July 18, 1921; in the Car- 
negie Museum, Pittsburg, Pennsylvania. 
Allotype : same locality and date as holotype ; in the Car- 
negie Museum, Pittsburg, Pennsylvania. 
Paratypes: 1 $, Rector, Pennsylvania, July 31, 1921; 1 
$, Allegheny Co., Pennsylvania, July; in the Museum of 
Comparative Zoology. 
This unusual Panorpa is closest to anomala Carp, in both 
wing markings and genitalia. The male genital bulb of 
bifida , however, has longer forceps and hypovalvse, and the 
shape and lengths of the ventral valves are very different. 
The internal skeleton of the female genitalia has a much 
broader incision posteriorly than that of anomala. In my 
key to the males of Nearctic Mecoptera (Bull. Mus. Comp. 
Zodl., 72 (6) , 1931) bifida runs to the couplet containing dis- 
similis and decorata (28), from both of which it can readily 
be separated by the forked ventral valves. The female runs 
to the last group of species under number 22 and can be dis- 
tinguished from the species included there only by the struc- 
ture of the internal skeleton. 
Panorpa flexa, n. sp. (Figure 2.) 
Head, thorax and first 6 segments of abdomen dark- 
brown, nearly black; abdominal segments 7-9 yellowish- 
brown; anal horn absent. Fore wing: length, 11 mm. width, 
3 mm. ; membrane colorless, markings light brown, all bands 
interrupted; both marginal and both basal spots absent, 
cross veins margined. $ genitalia : genital bulb rather slen- 
der, forceps of moderate size, without lobes; a cluster of 
heavy, black hairs at base of forceps; hypovalves long, al- 
most reaching to the base of the forceps ; ventral valves con- 
sisting of a long, cylindrical, glaborous shaft, smoothly 
curved ; at the base of this shaft is a cluster of 5 radiating 
barbs; an abruptly tapered point terminates the shaft it- 
self. Female unknown. 
Holotype ( $ ) : Indian Pass, Smoky Mts., N. Carolina ; 
September 4, 1933 (C. F. Walker) ; in the Museum of Com- 
parative Zoology. 
This locality is almost identical with that at which the 
types of P. longicornis and many other Panorpas were col-
