West Australian Coccidiv. 461 



Adult $ elliptical, dark brown, tapering behind, closely resembling 

 G. banksiae ; the antennte and dorsum exhibiting the same characters. 

 Abdominal cleft represented by a deep narrow slit ; lobes adjacent 

 and tapering. Anal ring apparently hairless, and tube distinct* 

 Region surrounding cleft and lobes conspicuously chitinous. Margin 

 with a regular row of yellow, cylindrical and coronetted spinnerets 

 from which the test is secreted. 



Immature $ naked, elliptical, with a longitudinal carina. Resem- 

 bling adult in all anatomical features except the anal lobes, which 

 resemble the tubercles of an Eriococcus, tapering and bearing at the 

 apex a long, acuminate spine, also 3 other spines, one upon the 

 upper surface and two upon the inner margin. 



^ puparium, glassy, white, the medium region very much raised. 



On Dryandra nivea, Darling ranges, and on Dryandra 

 Jloribunda, Perth. The arrangement of the test is not 

 easily described, but is fairly reproduced by the figure ; it 

 is particularly neat and pretty, and may be likened to the 

 well-known crest of the Prince of Wales. The genus 

 Dryandra is peculiar to West Australia, and its members 

 are closely allied to the Banksias. 



BRACHYSCELINiE, Maskell. 



As pointed out in my reference to the Genus Apimorpha 

 I propose to replace that as the type genus of this sub-family 

 by Ascelis, and include with it the genera Opisthoscelis and 

 Gystococcus. 



Genus Ascelis, Schrader. 



Insects gall-inhabiting. $ s undergoing their transforma- 

 tions within the ^ chamber, or gall. Adult $ s without 

 legs, abdomen somewhat prolonged and ending in a 

 chitinous button. 



65. Ascelis Melaleuca}, sp. n. (Plate XV, fig. 35, 85 a.) 



Adult 9 yellow, sub-globose, abdomen tapering and ending in a 

 bard, chitinous button. Length about /^ inch. Body unsegmented. 

 Mouth somewhat rudimentary. Legs and antennae absent. When 

 cleared in potash 6 chitinous ribs are seen to extend into the body 

 from the terminal button. Spiracles distinct. 



Gall wider than high. Externally of the same nature and colour 

 as the bark of the host plant. Apex of gall conical ; perforated by a 

 small orifice, through which a glassy filament occasionally protrudes. 

 Galls divided into two chambers, the lower is occupied by the 9 and
