THE GENUS NARNIA STAL, AND A KEY TO THE 
GENERA OF ANISOSCELINI A. AND S. (COREIDE: 
HETEROPTERA). 
By Epmunp H. Greson and Assy Ho.LprinGE, 
Bureau of Entomology, Washington, D. C. 
Members of the genus Narnia Stal present an interesting group 
in the tribe Anisoscelini A. and S. as well as presenting difficulties 
to the systematist. In 1862 Stal described the genus to include 
his femorata and later, in 1870, he described N. pallidicornis, both 
descriptions being made from single specimens. Since then three 
other well defined species have been added to the genus. Now, 
from the study of a large series of specimens it appears that Stal’s 
two species are the same and one species, with the name femorata 
retained. ‘The characters which he gives for separating pallidi- 
cornis from femorata can not be termed stable, such as the color of 
the basal joint of the antenne, which varies to a considerable de- 
gree in nearly every species of the tribe. The late Mr. Otto 
Heidemann was of the same opinion as the present authors in this 
matter. Mr. E. P. Van Duzee, Entomological News, Vol. XVII, 
No. 10, pp. 384, 1906, has also voiced a similar belief when he 
stated that he suspected femorata to be a northern form of pallid- 
icornis. 
Mr. Van Duzee considers his species snowi and wilsont as form- 
ing a subgenus to which he gives the name Xerocoris. In this 
respect the authors disagree with Mr. Van Duzee and state 
that if there is to be any dividing of the genus it should be so 
as to group femorata and snow? together and inornata and wilsoni 
together. Such a grouping would be based upon the form of the 
dilation of the hind tibize which is quite generally accepted to be of 
greater importance than the relative breadth of insect and con- 
nexium, and form of prothorax. It seems quite unnecessary to 
recognize subgenera in Narnia.
