1918] Gibson and Holdridge—The Genus Narnia Stal 3 
Narnia wilsoni Van D. 
Narnia wilsont Van Duzee, Ent. News, Vol. XVII, No. 10, p. 
384 (1906). 
Wilsoni differs from all other species in that it is much smaller, 
and has red colorations on apex of head, basal joint of antenne, 
and legs. 
This species occurs in California. 
A Key to the Genera of Anisoscelint A. and S. 
The following key includes all of the genera of the tribe Ani- 
soscelini A. and S. Representatives of but three of the genera, 
Chrondrocera Lap., Leptoglossus Guer. and Narnia Stal occur in 
American north of Mexico, the other genera being limited to Cen- 
tral and South America. 
The tribe may be characterized as follows: Head elongate, 
antenne long and more or less slender. Thorax trapezoidal in 
form, greatly depressed anteriorly, posterior lateral angles more or 
less acutely angled. Posterior femora sometimes swollen but not 
incrassated. Posterior tibiz with a broad thin dilation or fo- 
liation which is often wider than the width across the elytra. 
The genera may be considered as grouped into two divisions, 
Anisoscelaria n. n. those having the joints of the antenne simple as 
in Anisoscelis and Chrondroceraria n. n. those having the joints of 
the antennz more or less dilated as in Chrondrocera. 
The authors feel justified in placing Stenoscelidea within this 
tribe as the characters of the hind tibie are of greater importance 
than the form of the antenne.
