 of terminal antennal 

 segment :

 abdominal segment

Table B 



Pseudoccidae 



Comparatively thin. 



All preapical, or the dorsal one 



removed a greater distance 



from the apex. 



Rather long, slender, uniformly 



tapering to a pointed end. 



As long as other abdominal 

 setae. 



With a pair of long setae and 



one or more much shorter 



ones. 



Three or more setae, subequal 



in length to the abdominal 



setae, occur on each side of 



the median line. 



Eriococcidae 



Rather stout. 



All near the base of the 



segment, or only the dorsal 



one preapical. 



Rather short and stout, broad 



at base and abruptly tapering 



to a pointed end. 



Include one conspicuously 



long seta on each side of the 



segment. 



With only one pair of setae. 



Two setae, much longer than 

 the abdominal setae, are 

 always present on each side. 



There is also a number of supporting characters (listed in table C) whose presence 

 or absence obtains in one of the two families, but whose alternative conditions 

 occur in the other.
