The description given by Cockerell needs to be amplified at 

 several points. 



The adult female is in general form 

 entirely like the other members of the 

 genus to which I am referring the species. 

 Legs entirely lacking. Pores of the 8- 

 shaped type small, confined to a narrow 

 zone extending about the body at the 

 lateral margin. Tubular ducts abundant, 

 small, slender, usually presenting an 

 elbowed appearance. Two pairs of cribri- 

 form plates present, the members of each 

 pair close together. Anal ring with 10 

 setae. Anal lobes quite small, their mesal 

 margins but slightly chitinized. Between 

 the lobes is the characteristic "cauda" of the genus. 



Cockerell states that the antennse of the first stage larva are 

 6-segmented, but all the specimens examined by me show but 5 

 segments. The matter is not especially important as the first 

 stage larva in other species of this genus may show either 5 or 6 

 segments. The 8-shaped pores of the dorsum are much smaller 

 than those of the marginal series. 



Specimens examined. — Part of the type material. 



Notes. — Green has already pointed out (ref. cited) that this 

 species appears to be close to Cerococcus. I am unable to find any 

 basis for separating it generically from C. quercus.
