SUBFAMILY OEDIPODINAE Gal 
-the statement that I would get out and collect some specimens of this 
Hippiscus. Upon making a search, we found several specimens, much 
to Mr. Metzger’s astonishment. The almost invariable rule in this lo- 
cality is that where we find this dwarf sage on gravelly hillsides, we 
have taken this insect. 
The only record of this species in this part of the country was 
based upon a single specimen taken by Dr. J. A. Allen, at Denison, 
Iowa, July 15, 1867. Walker has twice reported taking it in Canada, 
while all other records are from Colorado and westward. We have 
taken it in abundance throughout Ottertail and Wilkin counties and 
at Halstad, Fertile, and Hallock. 
DISSOSTEIRA Scudd. 
The body of the Dissosteira is slender and somewhat compressed, 
with the head prominent; the vertex more or less tumid, declivent, the 
disk subpentagonal or nearly ovate, the lateral foveolae trigonal ; lat- 
eral carina low and the median present but very weak. The pronotum 
is tectate on the prozona and flattened on the metazona; the median 
carina strong and sharp, strongly arched on the metazona; deeply but 
narrowly notched before the middle; lateral lobes deeper than broad, 
anterior and posterior margins nearly straight, the anterior vertical 
and the posterior more or less oblique; inferior margin posteriorly 
rounded and anteriorly ascending; tegmina long and quite broad, the 
apical third membranceous; wings long and broad, in our species, 
blackish with a light outer margin. But one species is known to occur 
in this State. 
Dissosteira carolina L. 
Dissosteira carolina is one of the most common of our Orthop- 
tera (Plate II, 2 and 3) and possibly the one most generally noticed 
by the great mass of persons not particularly interested in this group, 
as it may be seen almost everywhere during midsummer. It is an 
insect primarily of dusty places and may be found wherever bare 
earth, sand, or clay is exposed. It is moreover equally at home in the 
busy streets of a city or the deserted roadways of the country. We 
may find it also in meadows, on railway embankments, or along the 
margins of lakes or streams. Wherever we find this versatile species 
we may note that its coloration fits perfectly the background of its 
habitation. There appears to be a rather definite adaptation of colora- 
tion to environment, since in a large series taken upon open sandbars, 
there is usually a predominance of light-colored forms, more or less 
closely simulating the coloration of the sandbar, while in a series taken
