The following description is that given by the author of the species: 
Frontal costa depressed at the ocellus. Head but slightly elevated above the pro- 
notum. Foveolaofthe srertex scarcely depressed. Carinaeofthe pronotum nearly 
obsolete; the median rut by bhe three transverse incisions. Hind lobe of pronotnm 
slightly rngulose. Tegmina extending beyond the abdomen, nnnsually narrow. 
Male eerci small, narrow, straight, tip rounded and silicate. Tip of abdomen 
notched, as in M. spretus but the notch is wider. 
General color light brown. Upper part of pronotum and hind femora with a red- 
dish tinge. Face sometimes mottled. Antennae lighl brown, infuscated apically. 
The usual black band behind the eye. broad and distinct, and reaching lasl division 
of pronotum, bounded below by a narrow white stripe. A broad white stripe from 
base of tegmina connects witli a white stripe at insertion of posterior femora, form- 
ing a right an<;le. Outside of hind femora crossed by two indistinct dusky hands 
that extend upon the upper edge. Lower sulcatum reddish. Knees black. Hind 
tibia? blue. Tegmina light brown, with very small black spots in the disk. 
Length of body — male, 22.5 mm , female, 24"""; of tegmina — male, 17 mm , female, 
19 mm ; of hind femora — male, 12. 5"' m , female, 14 mm . 
As intimated above, this locust at first appeared to be one of the 
few species that are confined to special food plants; but now it has for- 
saken the single plant and takes up with a great variety of others. 
Since its food was originally the Artemisia ludoviviana its distribution 
was necessarily limited to regions where that plant flourished. With 
the change in its food habits so as to take in other plants it also was 
permitted to spread over more country. Xow it occurs both on high 
and low lands, but appears to be somewhat partial to old breakings 
and well-fed pastures of many years' use. It occurs in eastern Montana, 
North Dakota, South Dakota, Iowa, Nebraska, Kansas, and Texas. 
THE HERBACEOUS LOCUST. 
(Melanoplus herbaceus Bruner.) 
During the fall of 1887 the writer, while spending a few days at El 
Paso, Tex., took a large number of a rather large but slender Melano- 
plns upon various kinds of weeds and other low vegetation growing in 
the vicinity of the town along 
the banks of the Rio Grande. 
This locust was present in large 
numbers and did some damage. 
Like the M. angustipennis, it is 
rather an above-ground insect 
than a ground frequenter, and 
for that reason would be more Fio. 13.-Melonophi9 herbaeeut: a, female-natural

come numerous, than are many others. 
Aside from these few notes nothing thither of its lite history and 
habits are known to me, but it is presumed that tlie insect does not 
differ greatly from the species of the genus with which we are familiar, 
The following description of the present species is herewith added,
