pronotum sprinkled with black; antennae annulated with fuscous. Pro- 
notura with the posterior margin acute angled; crest somewhat prom¬ 
inent, profoundly incised between the lobes. Elytra pale, grayish- 
brown, somewhat translucent toward the apex, where they are also 
clouded with fuscous. Wings pale yellow at base, with a broad black 
band aross the disk arcuate and narrowed internally; apex transparent, 
with fuscous veins. Anterior legs subannulated with fuscous; posterior 
femora with the facias and apex black, the inferior margin and exter¬ 
ior side hairy; posterior tibiae pale yellowish, fuscous at the base; spines 
tipped with black; hairy. 
Female .—Length, 25 millimeters. 
I am inclined to think that this is found only in the extreme 
northern parts of this State and in Michigan. Prof. Peabody informs 
me that he has found some specimens in the extreme northeast corner 
of the State which he is inclined to think belong to it. 
17. TRIMEROTROPIS VERRUCULATA. Scudd. 
Although placed by Mr. Scudder in a different genus it is closely 
allied to Oedipoda aequalis , from which it differs as follows : 
Frontal costa of the female rather more distinctly sulcate. Middle 
carina of the pronotum less distinct on the posterior lobe, and a little 
less elevated on the anterior lobes, notched and severed in two places, 
the middle portion the shortest. Elytra and wings appear to be a 
little longer compared with the length of the body, and the wings 
more distinctly papilioniform. 
Color. —Ash-brown, varied with dusky-brown. Face ash-brown with 
dusky dots, male darkest. Pronotum a little darker, dusky spots 
larger than on the face; lateral stripes scarcely distinguishable. The 
black band of the wings is narrower, the outer and inner borders 
more irregular, somewhat broken at the first sub-frontal nerve, does 
not reach the anal angle; the sub-frontal space dusky nearly to the 
base; apex dusky, with a few small fuscous dots. Base and apex of 
the posterior tibiae black; middle portion yellowish or plumbeous, 
generally, with a dusky annulation near the middle. 
Dimensions. — f- —Length, 1.10 inches; elytra, long as the body; 
posterior femora, 0.57 inch; posterior tibije, 0.5 inch, m —Length, 0.9 
to 1 inch.
