The third form of R. virginicus 
This smaller southern species was, like the northern, at first 
known only in the enlarged adult phase, but in looking over 
unstained material and mounted specimens, both the nymphal 
and young adult phases have been detected in specimens that 
were formerly considered workers. 
In figure 11, the head of an enlarged adult is shown, and in 
figure 12 the reproductive system of a young female nymph 
which is not yet mature. It will be noted that the ova have 
begun to enlarge, whereas the fusion of the three parts of the 
reproductive system, ov., s.r., c.g., is not wholly completed. Asa 
transition phase in development this specimen is especially 
interesting.
