femora crossing that surface or limited to its inner portion. The 

 caudal tibiae range from primuline yellow to buffy. 



Though ranging in general coloration from light yellow to 

 brown, a distinctive and similar general facies is shown, widely 

 different from that of the other races of foedus. 



While joedus joedus Scudder is particularly apt to be found 

 in restricted sand areas but often occurs as well on sandy plains 

 or river bottoms to the west, both joedus fluviatilis and foedus 

 iselyi are decidedly more local in distribution and are probably 

 largely confined to sandy areas along rivers, streams and lakes, 

 in the regions in which they occur. It is evident that the former 

 is a northeastern and the latter a southeastern race.
