THE CANADIAN ENTOMOLOGIST 325 



Ventral side of the abdomen with a pair of small, circular, cribri- 

 form plates. Dermal pores quinquelocular, somewhat pentagonal 

 in form. Anal ring appearing on the ventral side in the adult 

 female, small, simple, with six small setae. First stage larvae 

 with 3-segmented antennae. 



Type of the genus, Sphcerococcus parvus Maskell. 



Notes. — The original description of .this genus consists merely 

 of a quotation from a letter by Cockerell to the effect that, "Ku- 

 wanina differs from Antonina by the larva having 3 or 4-jointed 

 antennae." It is rather difficult to understand why the genus 

 was compared with Antonina rather than with the type of the 

 genus from which it was removed.

There is little to add to the description given by Green, other 

 than to note that the pores are borne at the inner end of short 

 ducts and that the derm of the abdomen presents a curiously 

 roughened appearance. I have examined specimens from the 

 material recorded by Kuwana in 1902. Mr. Morrison has sent me 

 sketches made from the type of the species and these leave no doubt 

 as to the correctness of the determination. 



Ehrhornia, n. gen. 



Coccidae of the type described above. Adult female with 

 well developed legs and antennae, the latter 6-segmented. Ventral 

 side of the abdomen without cribriform plates. Dermal pores for 

 the most part circular and without distinct loculi. Anal ring
