Stal, but is regarded by Brunner as a member of the Oedipodinae, 
in which case it must fall in the Eremobini, where it would be very 
distinct from all other genera. The type is certainly a peculiar one ; 
the species here described is rightly referred.

1875. Peru. 
Stal (Syst. Acrid., 40) distinguishes from other genera allied to 
Tetrataenia one based on Acridium longipenne De Geer, which he 
referred with hesitation to my genus Cornops. To judge from his 
table alone, he was entirely correct in his surmise. 
48. Elaeochlora brunneri, Proc., 17, 270; Ent. Notes, 4, 24. 
1875. Peru. 
This belongs to a new genus near Catreus Stal, in which the 
dorsal carina of the hind femora is distinctly spined, and the anten¬ 
nae have but 15-16 joints. It may be called Locheuma (Aoyev/>ia). 
49. Euparnops caeruleum , Proc., 17, 275 ; Ent. Notes, 4, 29. 
1875. Peru. 
This genus founded on the present species is the same as Tetra¬ 
taenia Stal, which when first characterized was wrongly placed by 
him in the series in which the lateral margins of the hind tibiae are 
neither dilated nor acute, owing to the fact that the specimens he 
then had lacked these members. The position of the genus was 
afterwards (Syst. Acrid., 39) more correctly defined. 
50. Gomphocerus clepsydra , Daws. Surv. 49th parall., 4. 1875. 
Assiniboia. 
A true Gomphocerus. 
51. Hlppacris crassa , Proc., 17, 268 ; Ent. Notes, 4, 22. 1875. 
Peru. 
I have further discussed the position of this curious genus in 
Psyche, 5, 433-434 (1890) and shown its close relationship to Saus- 
sure’s Daemonea. 
52. Eophacris liumboldtii , Proc., 12, 337 ; Ent. Notes, 2, 22, 40. 
1869. Peru. 
In his Recensio Orthopt., and also his Syst. Acrid., Stal unites this 
genus with Titanacris Scudd., and retains the latter name. The 
differences originally pointed out by me, especially in the pronotal 
crest, the venation of the tegmina, and the scalariform portion of the 
wings, still seem to me to warrant their separation as distinct genera. 
53. Machaerocera nigromarginata, Proc., 17, 268; Ent. Notes, 
4, 22. 1875. Peru. 
This species I subsequently (Psyche, 5, 433, 439) referred to a
