SUBFAMILY OEDIPODINAE 4} 
were slightly curved in their long axes. Both ends were rounded, but 
the cephalic or head end was slightly smaller than the opposite one 
and further distinguished in the fresh eggs by the very small densely 
opaque, cap-like structure occupying the tip.” This species has been 
found throughout the State and at times in favored localities increases 
to sufficient numbers to do noticeable damage to crops. 
ENCOPTOLOPHUS Scudd& 
Body of medium size, somewhat slender though not so much so 
as in Chortophaga, somewhat compressed; the head slightly swollen; 
vertex more broadly triangular than in the preceding and somewhat 
declivent, lateral carinae weak, apex obtuse in females, median carina 
present but terminating at middle of disk. The antennae rather long 
and slender, longer than head and pronotum together, especially in 
the males, the joints somewhat flattened. Pronotum with disk flat- 
tened, the median carina distinct or strong, notched near the middle ; 
lateral carinae visible only on the metazona. Anterior margin of the 
pronotum truncate, hind margin sharply angulate; lateral lobes deeper 
than long, much wrinkled, front and hind margins nearly straight and 
vertical, the posterior more oblique and with the lower corner rounded. 
Pronotum less constricted anteriorly than in the preceding genus. Teg- 
mina broad and longer than the abdomen with the intercalary vein 
distinctly nearer the ulnar than the median. But one species 1s known 
in Minnesota. 
Encoptolophus sordidus Burm. 
The color of Encoptolophus sordidus (Plate I, 8) varies 
through the shades of brown, and the somewhat mottled pattern sug- 
gests some of the dark forms of Hippiscus. There is usually a light- 
colored, pink-tinged, X-shaped mark on the disk of the pronotum, 
very conspicuous in dark specimens. The tegmina are marked with 
two transverse, light-colored bars near the middle, which contrast with 
two larger fuscous patches between and on either side of them; the 
inner wings are yellow, somewhat clearer toward the base and smoky 
apically. The antennae are brownish, darker apically. The hind 
femora are banded or almost covered with fuscous; hind tibiae dark, 
with a pale annulation near the base. 
This species matures late in summer and during August and early 
fall may be found in some numbers in dry sandy areas. We have gen- 
erally taken it amid such vegetation as Aristida basiramea Eng. and 
Bouteloua hirsuta Lag., although it is also found even far out in culti-
