dition to these, in the Illinois Natural 
History Survey collection is one cotypic 
female secured by exchange as noted 
above, and my notes indicate that another 
cotypic female is in the collection of Cor- 
nell University. It should be mentioned 
here that all of the cotypic specimens 
show traces of a faded dark dorsal stripe 
on the abdomen. Such a stripe is often 
dificult to see in old specimens, and this 
undoubtedly partly accounts for the mis- 
identification of material by Needham & 
Claassen (1925), 
Due to the kindness of Dr. Nathan 
Banks, I was permitted to relax one of 
the male cotypic specimens and place it in 
alcohol for closer study and comparison 
with a paratypic male of lodgeit Frison. 
It is highly desirable that this male co- 
typic specimen in the collection of the 
Museum of Comparative Zoology, and 
now preserved in alcohol, be selected as 
the lectotype; I now so designate it. 
The cotypic specimens of nanina all came 
from “Black Mountain, North Carolina, north 
fork of the Swannanoa River, May.” The 17 
specimens comprising the typic series of lodgei 
(= nanina) all came from “Fighting Creek, 
branch of Little Pigeon River, Gatlinburg, 
Tennessee, May 27, 1934,” which is in the 
same general region.

Original description, ¢, 2. New synonymy. 
Thanks to Dr. W. E. Ricker, I have 
had an opportunity to study the terminal 
abdominal segments of the holotypic male 
of concolor belonging to the Royal On- 
tario Museum of Zoology, ‘Toronto, Can- 
ada. The study of the holotype confirms 
earlier suspicions that concolor is specifi- 
cally identical with neglecta and therefore 
is a synonym of the latter species, which 
has date priority. Dr. Ricker in a letter 
to me states that he concurs with my opin- 
ion concerning this synonymy. 
This species was originally described 
from the male sex only and was based 
upon material from ‘“‘New Found Gap,

additional material, including the unde- 
scribed female, has been taken in the same 
general locality and its description is now 
presented. 
FEMALE.— Head, thorax, basal abdom- 
inal segments and appendages in general 
similar to those of the male ( Frison 
1935, p. 336) but slightly larger in size. 
In life, specimens are a pale apple green.

Important differences are as follows: 
eighth abdominal sternite, fig. 124, with 
posterior margin produced backwards in 
a V over ninth sternite. 
Allotype, female.—Gatlinburg, Tenn., flying

Female specimens were taken at the same 
time and place as males, and since only three 
or four species differently colored were on 
the wing at the time there is no doubt of the 
correct association of this female as neglecta. 
Additional records for this species are as

This species has not been recorded since 
it was first described in 1925 from a single 
male specimen collected at “Truro, Nova 
Scotia.”” Recently, additional material, in- 
cluding the previously undescribed female, 
has been studied and the following descrip- 
tion and records are therefore presented.
