tionately long, seldom less than and often exceeding the length of 

 the tibia. This character is somewhat exceptional amongst 

 Coccidse. The anal orifice ^except in Kermes) is surrounded by a 

 setiferous ring. 



The larvae are usually rather narrow and taper behind : the 

 body terminating in prominent lobes, each bearing a stout seta 

 and two or three slender spines. There are similar slender spines 

 on the dorsum — usually in transverse series across each segment. 



Eriococcus is the only genus represented in Ceylon.
