Nearly uniform dark fuscous, often ash-color sprinkled over with 
fuscous dots, males sometimes almost black; face paler, dotted over 
with black points; mouth whitish or pale; outer joints of the palpi 
usually whitish or pale; pronotum above, is sometimes paler, of a dull, 
dirty-yellow, or partially of this color, usually dusky or brown. Elytra 
almost uniformly mottled with fuscous, the outer half interspersed 
with paler spots; but the shading varies in depth. Wings with the 
broad basal portion bright red; a broad black band around the 
outer margin, with a dark sub-costal ray extending toward the base; 
the extreme tip transparent more or less, clouded or spotted with fus¬ 
cous. Posterior femora usually crossed externally by three pale 
bands; posterior tibiae black at the knee, below which is a pale ring, 
middle portion varying from bluish green to black. The pale mark¬ 
ings are very variable and sometimes entirely absent. 
The size of the female varies from 1.5 to 1.8 inches to tip of elytra; 
of the male from 1.15 to 1.4, 
This species has been observed occasionally in the extreme north¬ 
western part of the State. As will be seen I have adopted the name 
T. nietanus , of Saussure, instead of T. tenebrosus , of Scudder: further 
study of the species has sufficed to convince me, nothwithstanding the 
statement in my Synopsis, that the two are identical or but varieties 
of one species. The only character given by Saussure, which leaves 
any doubt, is the carina in the lateral foveolae of the vertex : I find 
occasionally a minute tubercle which appears to represent it, but have 
so far failed to find a true carina in these. 
13. OEDIPODA AEQUALIS. Say. 
Vertex of moderate width; foveola very shallow, especially in the 
female, slightly elongate, and in the male divided by a dim carina; 
lateral foveolae almost obsolete; frontal costa sulcate, slightly in the 
female, more distinctly in the male, reaching nearly or quite to the 
clypeus. Median carina of the pronotum prominent on the anterior 
lobes, distinct, but less prominent on the posterior lobe, severed once 
near the middle, with a notch; front part compressed as usual, but 
less wrinkled than many other species; posterior lobe nearly flat on 
the disk, slightly rugulose, especially in the female; anterior margin 
slightly angled; posterior extremity about a right angle; lateral carinse 
subdistinct, rounded. Elytra and wings passing the abdomen about 
one-fourth their length. Posterior femora in the female about as long 
as the abdomen. Antennae passing the thorax. 
Color. —Ash-gray mottled with dusky-brown and white. Face white, 
mottled with fuscous, or fuscous mottled with white; occiput dark- 
fuscous. Pronotum dusky-brown, with a dim, pale, broad stripe along 
tho margins of the disk, bending inward at the middle with the lateral
