equal sections by a distinct, longitudinal, median carina that extends back part way 
upon the occiput ; sides of tho foycola parallel between the eyes, and bending abruptly 
inward toward the fastigium, in front, continuous with the sides of the frontal costa; 
fastigium with a double; indentation. Frontal costa slightly snleate, suh-tricarinate 
at tho fastigium, widening at tho ocellus and extending nearly or quite to theclypeus, 
but not expanding below; in tho <J the width is almost uniform throughout. Pro. 
notuni, wit h tho median carina sub-cristate, distinctly and deeply notched about the 
middle by tho posterior sulcus ; anterior portion irregularly arched, more elevated than 
tho posterior portion, which has only tho front part arched; lateral carina) irregular 
and indistinct ; the notch of tho median carina is of the oblique type, more distinctly 
so in tho male than in the female. Posterior lobe expanding rapidly from the posterior 
sulcus, nearly flat on tho disk, which is more or less covered with elongate rugosities, 
more distinct and numerous in the female than in tho male ; posterior extremity ob- 
tuse-angled ; anterior margin extended in a very obtuse angle upon the occiput. Ely- 
tra extending about one-third their length beyond tho abdomen, of medium width, 
sinuous and obliquely excised at the tip. Wings narrow, the length very nearly twice 
the width, and slightly undulate on the outer margin ; tho nervules unusually regular 
and straight. Posterior femora with sharp and elevated carina) above and below. 
Antenna) rather short, scarcely flattened, and very slightly acuminate at the tip. 
Color (recent specimens dried). — Female somewhat darker than the male ; face pale 
purplish, dotted with fuscous; occiput and pronotum fuscous brown, the latter with 
a carneous stripe along each lateral carina, which connect at the anterior sulcus and 
fade out near the posterior extremity ; the disk of the posterior lobe dark brown. 
Elytra pale, dirty yellow, slightly tinged with rufous, crossed by three irregular bands 
formed of dark fuscous spots, tho middle one broadest and usually tho best defined ; 
apex with irregular, cellular, fuscous spots, those next the costal margin most distinct. 
Wings pellucid, with a narrow marginal, rather pale, fuscous band, commencing be- 
hind the sub-costal area, where it is broadest, narrowing and fading toward the anal 
angle ; tho nerves and nervules, except in the apical portion of the sub-costal area 
and iu tho fuscous band, pale yellow, or white. Posterior femora crossed externally 
and internally by three oblique fuscous bands ; posterior tibia) pale yellow ; spines 
tipped with black. 
One male and one female from Sierra Valley, California, furnished by Mr. J. G. 
Lemmon. 
This species approaches very near Mr. Scudder's Trachyrhachys, but appears to belong 
to (Edipoda, as at present limited. If Mr. Scudder's genus Dissosteira (of which he has 
given but an incomplete diagnosis) stands, this species will scarcely find a lodging- 
place in any of the numerous genera of this group. 
In his paper on the Orthoptera collected by Lieutenant Wheeler's survey, published 
in 1876, where he first proposes this genus, he makes the following statement : Stal's 
limitations of the genus (Edipoda, in his Recensio Orthopt. I, forces us to consider G-ryl- 
lus coerulescens, Linn, as the type, and not, as stated by Thomas, (Edipoda Carolina 
(Burin)." 
He alludes to a statement made in my paper on Orthoptera, in a previous report of 
the same survey, where I simply remark that Stal has retained our (E. Carolina, and 
that "this appears to he his typical [species]" (by typographical or clerical error 
"genus"). By reference to Proceedings Davenport Acad. Nat. Sci., vol. i, 1876, page 
257, it will there be seen that I make the following statement in reference to the genus 
(Edipoda as given by Stal : "In my opinion (E. coerulescens, Linn, is the proper type of 
(Edipoda." This paper was published in June and July, 1876, the entire manuscript 
having been forwarded to Mr. Putnam some time previous thereto. I cannot give the 
exact date of publication of Mr. Scudder's paper, but his letter of transmittal to Lieu- 
tenant Wheeler bears date Cambridge, Mass., May 29, 1876. 
I simply mention this in justice to myself. 
As I have here referred to this paper by Mr. Scudder I may as well correct another
