THE ROUGH-HEADED CORN STALK-BEETLE 3 
DISTRIBUTION 
The known distribution of Huetheola rugiceps in the United States 
is Shown in Figure 1. The data upon which the map is based were 
obtained from the literature, from hitherto unpublished field records 
and correspondence of the bureau, and from personal correspondence 
with a number of museum and experiment station entomologists.* 
Euetheola rugiceps is recorded from all the Southern States lying 
south of the latitude of Washington, D. C., with the exception of 
Florida and Oklahoma. Judging by the erratic manner in which the 
species has been observed to occur in the infested sections of Virginia, 
it would be inadvisable to draw final conclusions regarding the limits 
of distribution from the evidence at present available. In Virginia 
the species was found only in that part of the coastal plain which 
lies between the Potomac and James Rivers, apparently preferring 
low, moist, poorly 
drained soils. Even 
within the area thus 
restricted, the spe- 
cles appears at 
present to be of very 
unequal distribu- 
tion, being abun- 
dant in certain lo- 
calities and rare or 
absent in others. 
It may be found va Me yt

fields, utterly de- 
stroying the corn. Lied Pot OTs: Wa Ese ee SN EL OE beens

fields of the same 
general type less than a mile away appear to be uninfested. Doubt- 
less there are unknown factors which influence and limit the spread 
of this species. 
The following is a list of localities, arranged according to States, 
from which there are records of the occurrence of the species.

Hartsells, Mobile, Sprott.
