In addition, latassa has been reported in the literature, under the 

 name georgiana, from Monte Sano State Park, Madison County, 

 Alabama, Hubricht, by Loomis (1943, p. 402); from Haleyville, 

 Winston County, Alabama, V. E. Shelford, by Loomis (1944, p. 173); 

 and from Pelham, Shelby County, Alabama, C. J. and M. Goodnight, 

 by Loomis and Hoffman (1948, p. 52). 



I.xtekgradation: Throughout its wide range, Cherokia g. latassa is 

 remarkably stable as regards its principal diagnostic character. In 

 Pact, this structural integrity, coupled with the quality level of its 

 difference from typical georgiana, led me to consider latassa as a dis- 

 tinet species for some time. This opinion gradually altered as a re- 

 sult of the realization that other equally important taxonomic characters 

 were distributed without regard to the two paranotal types, and with 

 the discovery of several specimens which, while clearly referable to 

 latassa, indicate the probability of intergradation with georgiana. 



A male from Steele, St. Clair County, Alabama (H. E. Evans), is 

 of interest in two respects: First, the scapulorae are completely mar- 

 ginal but become somewhat crenulated in outline toward the body; 

 they resemble the form taken in georgiana. Second, the sternal spines 

 are much longer than normal for latassa and also appear as distinct 

 subcoxal conicles on the 7th segment. 



A male from 3.5 miles northeast of Brent, Bibb County, Alabama 

 (L. Hubricht), does not have distinct subcoxal cones on the 7th 

 segment, but the scapulorae are almost directly transverse instead of 

 convex anteriorly, and thereby nearly subniarginal. While these 

 two specimens alone do not constitute direct evidence of intergrada- 

 tion, they show that the two paranotal types can be joined by inter- 

 mediate forms.
