SUBFAMILY OEDIPODINAE 47 
and now in the collection of Iowa State College at Ames. It has been 
taken from Nebraska to Arizona and the few specimens taken in Iowa 
and Minnesota probably represent merely the stragglers along its east- 
ern range. 
Hippiscus rugosus Scudd. 
Hippiscus rugosus is a well-known species, which while not com- 
mon, has been taken at several points within the State and when more 
extensive collections have been made, will doubtless be found nearly 
as common here as in Iowa. The following is taken from notes made 
upon this species while in lowa: ‘‘From the latter part of July until 
late in the fall, this is the most abundant member of this genus and 
appears to be very generally distributed throughout the State, although 
somewhat less abundant in the northern counties. It is found in dry 
places, especially along the margins of woods or thickets. It is gen- 
erally darker than other members of the genus and the disk of the 
pronotum is very uniformly marked with a light-colored X-mark. 
The wings vary from yellow to a reddish orange. We have found 
males as late as October 24, and females a week or more later.” In 
Minnesota the species matures late in August and we have taken it at 
Redwood Falls, Pipestone, Mankato, Albert Lea, Mahtomedi, and 
Fergus Falls. 
Hippiscus tuberculatus Pal. de Beauv. 
There is considerable variation in color in Hippiscus tuberculatus, 
although the following, taken from Scudder, will give a good idea of 
its normal form here: “Prevailing color a light ashy plumbeous, 
slightly darker above, specked with dark plumbeous, tinged slightly 
beneath with reddish; eyes dark brown speckled with yellowish brown, 
and with a narrow, slightly curved median streak slightly upturned 
behind. Antennae dirty yellowish at base, beyond of the color of the 
head. The pronotum with a longitudinal dark brown streak with in- 
distinct edges along the middle of the lateral lobes, and from the 
middle of this a descending vertical streak scarcely paler than the 
ground; posterior edge of the pronotum a yellowish brown, of the 
color of boxwood. Tegmina of the body color or blotched with fuscous 
and blackish and with the axillary fold yellowish brown. Wings coral- 
red at base, the arcuate band fuscous, deepening to black, the humeral 
line pale yellow and the apex nearly hyaline. Legs of the body color, 
the inside of the hind femora having the basal half a Prussian blue, 
the distal half very dull lemon-yellow, with a transverse streak of deep 
blue at one third the distance from the middle; hind tibiae dull lemon- 
yellow ; hind tarsi tinged with reddish.”
