8, 1932) by 0. L. Cartwright, is the first record for that 
state. 
Bittacus occidentis Walker 
Cat. Neur. Brit. Mus., 1853, p. 468. 
Two specimens were collected at Clemson College, S. 
Carolina, September 14, 20, 1932, by 0. L. Cartwright. 
This is the first record in the state. 
Family Boreidse 
Although no new species of Nearctic Boreus have come 
to my attention during the past year, a great many speci- 
mens have been received, some belonging to species which 
have previously been little-known. Of particular interest is 
a long series of both sexes of gracilis , which was described 
only from two females. The new females show that the type 
specimens of this species were slightly damaged to the 
extent that the long hairs covering the body had been rubbed 
off, producing the effect of a short pubescence. Since the 
nature of the pubescence was one of the characteristics 
which I made use of in my previous key to the females of 
Boreus (Psyche, 42:112, 1935), undamaged specimens of 
gracilis will not run to that species. In this connection, also, 
I wish to correct certain errors which were introduced into 
the above mentioned key. In some way the statements 
in couplet 7 were confused with those of couplet 6, and the 
changes pscaped my notice in the proof. The descriptions 
of the species concerned are of course correct, but for the 
sake of clarity and to correct the position of gracilis , I 
include here another key to the females of the Nearctic 
species of Boreus. 1 
Key to the Females of Boreus 
1. Fore wing reduced to a minute scar, similar to that of 
the hind wing reductus Carp. 
Fore wing in the form of a small oval pad 2. 
2. Wings and body the same color (brown or black) 3. 
Wings much lighter (yellow or yellow-brown) than body 
(dark brown or black) 7. 
X A typographical error in the key to the males of Boreus (ibid. p. 
Ill) is also misleading: in the second line of couplet 1, the number 
should be “9” not “8.”
