Although no specimens of flexa were among the several 
hundred Panorpas which were secured at that time, the 
specimen described was the only Panorpa which Mr. Walker 
collected in the vicinity. 
Since flexa does not possess the anal horn, it falls into the 
nebulosa group of Panorpa, and in my key (1931, p. 222) 
runs to couplet 7. As this couplet reads, flexa will not be 
covered by either choice; but if the first line of the couplet 
be changed to “ventral valves curved,” both flexa and sig- 
moides will be included. From sigmoides the new species 
can be distinguished by the shape of the ventral valves, 
which are sigmoidally curved in sigmoides but nearly semi- 
circular in flexa, 
Panorpa latipennis Hine 
Bull. Sci. Lab., Den. Univ., 11 : 248, 1901. 
Two females received from E. S. Thomas, of the Ohio 
State Museum, were collected in Ohio: Fallsburg, June 18, 
1932 (C. F. Walker), and Bay Point, Ottawa County, July 
18, 1931. These are the first records in the state and bear out 
my previous suggestion (1932) that latipennis probably oc- 
curred in Ohio and Pennsylvania. 
Panorpa suhmaculosa Carp. 
Bull. Mus. Comp. Zook, 72 (6) : 255; 1931. 
One female was taken by C. E. Mickel in Prince George 
Co., Maryland, July 27, 1929 ; this constitutes the first record 
for the state. 
Family Bittacidae 
Bittacus punctiger Westwood 
Trans. Ent., Soc. Lon., 4:195; 1841. 
One male, now in the Museum of Comparative Zoology, 
was collected at Dunedin, Florida, during March (Blatch- 
ley) ; this constitutes the first record in that state, although 
the species has previously turned up in neighboring states. 
Family Boreidae 
During the past two years several extensive collections of 
Boreus, mostly from western states, have been received for
