First stage larva without anal lobes; with the anal ring ex- 

 tremely minute and hairless; 8-shaped pores large, confined to 

 the margin of the body; antennae 4-segmented. 



Type of the genus: Sphcerococcus- pulchelhis Maskell. 



Notes. — Although this genus appears to be unquestionably 

 Asterolecanine it differs markedly from any other known to me. 

 I can say nothing in regard to its relationship with the other mem- 

 bers of the group. 



Callococcus pulchellus (Maskell). 



1896. Sphcerococcus pulchellus Maskell. Trans. N. Zealand 

 Inst., vol. 29, p. 324, pi. 21, figs. 10-13. 



The adult female of this species is 

 enclosed in a pretty, waxy covering 

 that has been well described by Maskell. 

 Morphological characteristics. — 

 Adult female merely an elongate, oval 

 sac, without appendages of any sort..

Derm membranes except for a narrow, somewhat irregular, 

 longitudinal, chitinized area extending the full length of the body 

 along the median line of the dorsum. This area appearing only 

 in fully mature individuals. Derm with many rather short, 

 tubular ducts, these especially numerous along the dorsal area 

 just described. Pores of the 8-shaped type extremely minute and 

 inconspicuous, confined to a row which extends along the median 

 line of the dorsum from one end of the body to the other. In the 

 fully mature insect this line of pores is almost entirely obscured 

 by the chitinization of the dorsum. 



First stage larva with 4-segmented antennae. Anal lobes 

 lacking, the posterior end of the abdomen pointed. Anal ring 

 extremely minute, hairless. Derm destitute of hairs and with a 

 single, marginal row of large, 8-shaped pores. 



Material examined. — Specimens determined by Froggat as 

 this species and agreeing in all respects with the original description.
