upon the pronotum. Antennae as long as the head and pronotum togcllier, dull honey 
yellow, growing dusky toward the tip. Pronotum dark brownish yellow, the sides 
darker anteriorly; median carina extending the whole length of the pronotum, mod- 
erately raised, cut once by a transverse line a little in advance of the middle ; lateral 
carina) prominent, extending across the anterior two-thirds of the pronotum; anterior 
border of the pronotum smooth, very slightly angulated ; posterior border delicately 
marginato, bent at a very little more than a right angle, the apex rounded; teginina 
dull yellowish on the basal half, with distinct fuscous spots; toward the apex obscurely 
fuscous, with indistinct fuscous markings ; humeral ridge yellowish, and, when the 
tegmina are in repose, inclosing a brownish fuscous triangular stripe ; the spots are 
scattered mostly in the median hold, consisting in thebasal two-lifths of the tegmina 
of small roundish spots and one larger longitudinal spot in the middle of the basal 
half; there is a large irregular spot in the middle of the tegmina, and beyond a smaller 
transverse spot, followed by indistinct markings; wings hyaline, slightly fuliginous 
at the extreme tip ; the veins, especially in the apical half, fuscous ; legs uniform brown- 
i-.li fuscous; apical half of spines of hind tibia; black. 
Length of body, 0.9 inch ; of tegmina, 0.9 inch ; of body and tegmina, 1.125 inches ; 
of pronotum, 0.2 inch ; of hind femora, 0.5 inch. 
It bears a strong resemblance to CEdipoda pellucida Scudd, common in Northern 
New England. 
Camnula tricarinata Stal. 
Pale brownish-yellow ; front on each side from the base to the lateral fovcolas and 
usually a stripe on each cheek below the eyes, black. Elytra in front of the middle 
somewhat brownish, fuscous, costal area pale, with fuscous spots; behind the middle 
dull hyaline with fuscous veins, and obsoletely clouded. Wings hyaline, colorless, 
with fuscous veins, posterior femora with two oblique fuscous stripes; posterior tibisB 
pale ; spines except at the base, black. 
Appearance and markings very similar to Tragocephala [CEdipoda'] sordida; vertex 
and fastigium narrower, sulcus of the frontal costa not reaching the base, antennas 
slenderer, lateral margins of the pronotum distinctly carinated throughout ; median 
carina less elevated, elytra narrower ; intercalate veins visible, radial area of the 
wings with no dilated areola;, and the exterior margin behind the middle obsoletely 
fuscous, posterior tibia? pale. Frontal costa sparsely punctulate, middle slightly exca- 
vated, base narrow. Vertex behind the fastigium furnished with a slender, abbrevi- 
ated, longitudinal carina; fastigium slightly deflexed slightly narrowed, slightly 
concave, lateral margins raised, marked with minute black lines. Lateral foveolae dis- 
tinct, triangular. Pronotum with shallow punctures on the lateral lobes but smooth 
on the dorsum which is flat ; median carina subcristate and equal throughout ; lateral 
margins distinctly keeled throughout, before the middle lobe parallel, distinctly diverg- 
ing posteriorly ; dorsum more or less distinctly fuscous, sides paler ; the lateral lobes 
are often marked with black or fuscous spots, the anterior of these spots interrupted 
by oblique paler marking. The mesosternal lobe in the male about double as wide, in 
the female a little more distant, as the metasternal lobes. Posterior femora medium, 
the margins entire.

The following description is drawn up by Mr. Thomas from specimens 
collected in Sierra Valley, California, by Mr. Lemmon, directly out of the 
hordes injuring the crops, from others collected by Mr. Marten, at Fort 
Peck Agency, Montana, and also by Mr. Thomas in Colorado : 
Camnula pellucida Scudd. 
Male. — Length of body .G5-.90 inch; to tips of elytra .80-1 inch; expanse of ely- 
tra 1.50 inches. Female. — Length of body .80-1 inch ; to tips of elytra 1 to 1.25 
inches ; expanse of elytra 1.75 inches. 
Occiput rising slightly above the pronotum, with a minute longitudinal median
