No. 394-] BLISSUS IN NORTH AMERICA. 815 
Whether this is in all respects similar to the Atlantic coast 
race or not is yet to be determined. This last is as yet known 
only in California, but it is not unlikely that it will in future 
be found to extend along the entire coast from California south- 
ward to Panama. The similar race that occurs along the 
Atlantic is at present known, to the southward, only to the 
Atlantic coast of Florida, not having yet been observed, so far 
as known, anywhere along the Gulf of Mexico. It must be 
stated, however, that except in the closest proximity to the 
sea, where Mr. Schwarz has found that it lives on the upper 
portion of its food plant, these brachypterous individuals are 
found only about the roots of their food plants, usually slightly 
below the surface of the soil, so that their detection is not an 
easy matter, unless one searches carefully for them. It must, 
therefore, be said that we really do not know whether this race 
occurs along the Gulf coast or not. 
A somewhat extended study of this maritime race in Ohio 
has disclosed some interesting differences between the habits 
of this and the exclusively macropterous race inhabiting the 
interior of the country. These differences, together with 
minor anatomical ones, have been thought by some entomol- 
ogists to be sufficient grounds for separating Say’s eucopterus 
from Le Baron’s devastator and making a separate species of 
each. I will give these differences between the two, as I have 
found them in Ohio, taking up first the maritime race. 
The Atlantic maritime race is composed of brachypterous 
and macropterous individuals, the relative number of each being, 
so far as observed, somewhat variable. As the macropterous 
individuals may take wing and abandon in spring the fields 
occupied by the two forms jointly, it is obviously impossible to 
make any estimates of their relative numbers except during 
hibernation or immediately after the young have developed to 
adults. I have not found that the macropterous individuals 
part company with the brachypterous individuals with anything 
like the celerity or entirety that has been observed in the case 
of the European species, B/issus dore, as witnessed by Professor 
Sajö. In our species both forms may be found together at all 
times, but where a field of corn or wheat adjoins a meadow, the
