1891 " ; one of " feet of female, 1891 " ; and by one unmounted female 

 and two galls under No. 226. The National collection of Coccidae 

 fortunately contains a few lots of this species, received from 

 various entomologists in Australia, and from these it has been pos- 

 sible to prepare additional mounts for study. The following descrip- 

 tions have been obtained from all the material available ; as Maskell's 

 description and figures of the gall seem quite satisfactory nothing is 

 added on this. 



Adult female. — Elongate, parallel-sided; derm clearing on boiling 

 in potassium hydroxide, except the posterior lobe of the body, this 

 remaining somewhat chitinized ; antennae acute conical, the segmen-

tation incomplete, but perhaps 5-segmented; with two small, incon- 

 sj^icuous eye-spots near the antennae; anterior legs stout, fingerlike, 

 the tibio-tarsal articulation very incompletely indicated, the tro- 

 chanter apparently fused with the femur; intermediate legs repre- 

 sented by large evaginated pouches or sacs at the apex of which are 

 small, somewhat chitinized plates, each bearing the rudiments of a 

 claw, digitules and some setae ; posterior legs represented by smaller 

 lobes with the apices even less developed than in the intermediate 

 pair; the prominence of these sacs apparently varying inversely in 

 proportion to the extent of the distension of the body through ovarian 

 development; mentum apparently 1-segmented, the additional seg-
