Division TIXGIDARIA. 

 Tingitaria, Stil. En, Hem, iii, p. 116 (1873). 



This division is at once separated from the preceding bv the 

 presence of an anterior pronotal vesicle or hood, which in some 

 eases completely covers the head : the area^ to the hemelyrra are 

 well defined, the costal area being frequently dilated. 



This is much the larger division of the Tingididas. and is 

 universally distributed.
