Oedipoda aequalis Ulil. (Say) in pari. Hcudder, Boston journ. 
nat. hist., v. 7, p. 470. 
Scudder made this species the type of the genus at tlie time 
of establishing it and revising the species. As lie gave no 
descri|)tion of it (save its generic characters with a diagnosis and 
a few remarks under bolli) and ns Say's description does not 
well charactei-ize the species, I shall describe the New England 
form here. 
Body compressed. Head of moderate size, compressed above, tumid 
at the sides below, especially in $, the occiput full above; vertex as 
declivent as occiput, broad, tapering rapidly, shallowly sulcate; the 
eyes separated by more than double the width of the basal antennal 
joint. Face very nearly vertical, in pi-ofile scarcely convex and rounded 
at meeting with vertex ; costa of moderate breadth, slightly narrowed 
above antennae, shallowly sulcate except at upper end ; lateral carinae 
sharp, distinct. Eyes rather small, about two fifths the depth of face 
from crown (top of head between eyes) to clypeus, the crown rising 
above them. (See fig.) Antennae somewhat shorter than hind femora, 
fuscous at tip, paler, often ochreous, rusty or even red basally, scarcely 
annulate at extreme base. 
Pronotum. (See fig.) Disk of pronotum moderately flat, least so on 
posterior half of prozona, the front margin considerably angulate; the 
posterior process acute, sharp-pointed, the sides excavate. Disk of 
metazona often slightlj' arched in median section and rather broadly 
joined to the median carina. Median carina high, arched on both lobes; 
strongly compressed on metazona and anterior half of prozona, on the 
posterior half of prozona sloping down to sides of disk. Dorsal edge of 
carina of prozona usually slightly arched and forming a backward- 
directed tooth in front of the notch. Incision oblique, deep, often 
fenestrate by reason of the lobes slightly overlapping. 
Tegmina passing hind femora by about one third their length, rather 
angulate on costal margin near base. 
Wings with the disk pale yellow, tbis margined distally by a broad 
fuscous band, Avhich is broadest on costal margin of wing, and narrows 
from its meeting Avith the hind margin of wing to the anal angle; it 
sends off a broad short shoot one third or one half way to base in the 
median and ulnar areas (subf rental shoot). This dark band is usnallj'. 
rountle<l on its distal margin, Avhere it joins the hind margin of wing, 
and is palest in color next the anal angle which it sometimes scarcely 
reaches, but always more nearly than in bolli. Tiie lateral and antero- 
posterior dimensions of the yelloAV disk are about the same and equal 
lialf the extreme length of wing. The fuscous band occupies the third 
((uarter on the costal margin. Tlie apical portion of the wing is trans- 
parent, usually more (J) or less ($) infuscated, often with fenestrate 
spots.
