Acrid, jiavovittatum ; olive-brown, with a yellow stripe on each side 
from the forehead to the points of the tegmina; the posterior tibisB 
and tarsi blood-red with black pointed spines ; it appears to be identical 
with Caloptenus femoratus, Burm., and is very hurtful to gardens. 
Locusta ((Edipoda) corallina, is perhaps identical with (E . phcenicop- 
tera, Burm. L. mavitima ; ash-grey, the face spotted with white ; the 
tegmina minutely spotted with brown, semitransparent at the point ; 
wings pale yellow at the base, with a band of blackish spots in the 
middle ; posterior tibias pale, with black tipped spines ; f-1^" long ; 
very abundant, but only near the coast. L. cequalis ; wings bright 
yellow as far as the middle, then having a broad black band ; posterior 
tibiae coral-red, with a white ring under the knee ; 1;^" long. L. lati~ 
pennis ; wings broad, their lower half bright yellow, then dark, with a 
regularly spotted band in the middle; posterior tibiae bright yellow, 
with a black ring under the knee, and a broad black tip. L. marnio- 
rata ; grey, marbled with yellow and black ; the lower half of the wings 
yellow, the middle having a broad black band, and the point two black 
patches ; posterior tibiae coral-red, having a black, then a white, and 
sometimes again a black ring under the knee, and a black point ; 7-9'" 
long. L. eucerata, allied to (E. fenestralis, Serv., but the wings are 
yellow, not red at the base. L. neb%ilosa ; wings transparent, with dark 
tips and a dark brown stripe on the anterior margin ; posterior tibiae 
brown, with a broad white ring under the knee ; 8-12'" long ; very 
common. Harris distinguishes a sub-genus, Tragocephala, by the 
antennas, which are shorter than the prothorax, and slightly thickened 
towards the point, the more oblique face and the mouth placed nearer 
the breast. It includes Acr. viridi-fasciatum, De Geer (Gryll. virgi 
nianus, F., chrysomelas, Gm., Acr. marginatum, 01., hemipterum, Pall., 
Beauv.) ; and two new species ; Tr. infuscata ; dusky brown ; prothorax 
finely keeled ; tegmina slightly spotted with brown ; wings transparent, 
pale greenish-yellow at the base, with a large dusky cloud towards the 
middle of the posterior margin, and a black stripe on the anterior ; pos- 
terior tibiae brown with a broad whitish ring under the knee ; length f " ; 
on the pasture lands of Massachusetts from May to the end of July. 
Tr. radiata ; nut-brown; prothorax keeled above; tegmina wholly 
brown but transparent at the tips; wings transparent, netted with 
brown and with black longitudinal veins slightly green at the base, a 
large dark cloud in the middle of the posterior margin, and a brown 
stripe on the anterior ; posterior tibiae reddish-brown, somewhat paler 
under the knees ; length above 1" ; rare in Massachusetts and North 
Carolina. A second sub-genus, Chloealtis, with a still more oblique 
face, longer antennae, a depression in front of each eye for the reception 
of the first antennal joint, prothorax without a keel, almost truncate 
posteriorly, and very short wings and tegmina ; might be arranged under
