to be more subject to jn^onounced dry periods, it is rather diffi- 

 cult to understand how such a resistant species as Cerion uva 

 could have been partially exterminated by these factors. In 

 addition, the living colonies are noi in tiie most hea\ iiy wooded 

 places. 



The specimens from the two colonies differ slightly from 

 each other in dimensions, and one lot is lighter in color than 

 the other. However, these divergences hardly seem worthy 

 of rank as separate forms. Some specimens show a slight 

 approach towards C. uva desculptum.
