These specimens differ somewhat from the typic material from Carolina on 
Acer spicatum in that the dorsal tubercles on abdominal III are larger in some 
cases and dark areas at bases of hairs are usually less evident. 
Chief Distinguishing Characters. Large partially united dorsal tubercles 
(.22-.30 long) on abdominal III and rather strongly bent, usually dark, 
cornicle.
