SUBFAMILY TRYXALINAE 29 
generally yellowish (Plate I, 6) in coloration. It was found at 
every point where collections were made and we are inclined to believe 
it generally distributed over our whole State. It may be noted in 
almost any habitat although it appears to be most at home in low moist 
areas. In early June the nymphs appear in and about such low 
grounds and these are doubtless its favorite breeding places, but later 
in summer it spreads out over all adjacent tracts and is one of the 
species that must be regarded as serious pests in Minnesota. In the 
extreme northern part of the State, at Lake of the Woods and else- 
where, we found certain variations of color that we did not note at 
any other points. In these the coloration was a dull brown tint, very 
similar to that of most of our Melanopli, while among them were forms 
more or less, occasionally quite distinctly, reddish, which had a strik- 
ing resemblance in the field to some species of Melanoplus. In other 
places we have noted the cheeks and sides of pronotum, together with 
more or less of the ventral portions of the body a distinctly green color, 
more or less variegated with brown. In fact an extended study of the 
variations of this insect would offer a very interesting problem. The 
flight of this little insect like that of most of the Tryxalinae is short 
and not particularly strong but the males are very active and have truly 
remarkable leaping powers. 
The following, from Mr. Howard’s insectary notes is of interest 
here: “May 27, 1912. Pod of eggs found near Foxhome; hatched 
May 30. July 8 adults appeared in field near Fergus Falls. Egg 
pods laid in cages were normal as compared with those dug up in the 
field. Three examined August 9 were from three-quarters of an inch 
to an inch long, and somewhat keg-shaped with the opening to the 
surface of soil tapering and slightly curved and contained five, six, and 
seven eggs respectively, placed on end in a vertical position in the keg- 
shaped basal part of the pod. Above them the tube was filled with a 
pinkish frothy mass. Eggs are of a brick-red color, with the surface 
roughened. This color makes them easy to distinguish from other 
species in the field.” 
GOMPHOCERUS Thunb. 
Gomphocerus includes a number of small insects of varied colora- 
tion, the structural characters almost exactly as in Stenobothrus, save 
that the antennae are clavate, having a short depressed club at the apex.. 
According to Bruner the tympanum is partly open. While but one. 
species has been noted in our collecting, the following key will serve 
to distinguish the only two species likely to be found in our State.
