Maskell. — On Coccididae. 67 



Length about oViii- The posterior extremity is usually open, 

 so that the puparium seems as if formed of an upper and 

 lower plate joined together for the greater part of their length, 

 between which the insect lies. 



Adult female yellow. The form is rather more elongated 

 than usual in the genus, and there is a shallow transverse 

 groove just below the rostrum. Abdomen ending in six 

 narrow lobes with rounded ends, and between them a few 

 very short hairs. The abdomen is somewhat tapering, and 

 the margin above the lobes is slightly serratulate. There are 

 no groups of spinnerets, but on all the abdominal segments 

 are rows of large single orifices, very numerous ; and on the 

 last segment these rows converge to the terminal lobes. At 

 the level of the rostrum are two small spinneret groups, each 

 having about six orifices. 



The male pupa may very easily be mistaken for the adult 

 female of some other Diaspid. It is reddish-yellow or brown, 

 somewhat elongated, subcylindrical with a tapering abdomen 

 which ends in six small almost contiguous lobes, and there 

 are a few converging rows of spinnerets as in the adult female 

 (three on each side). But the presence of only a single pellicle 

 on the puparium from which this form may be extracted 

 denotes clearly the sex ; moreover, on careful examination, 

 the commencement of the eyes and the rudimentary elytra may 

 frequently be detected. Length of insect about -gQ^n. 



Adult male unknown. 



Hab. In Australia, on Casuarina equisctifolia. My 

 specimens were sent by Mr. G. H. Brown, from Albury. 



This species, in the transverse groove of the female, ap- 

 proaches A. e^icalypti, Mask., but it is more elongated in 

 form, and the abdominal lobes and spinnerets differ: so also 

 does the male puparium. .

 p. 3. 



I frequently receive specimens of this insect, chiefly from 

 Victoria or South Australia (indeed, probably none have come 

 from New South Wales). The very rich colours of the puparia 

 vary to some extent : some are dark-brown, others almost 

 blood-red ; but the convex form and the orange - coloured 

 pellicles are present in all. The pellicles are frequently raised 

 in a small boss, which, indeed, sometimes has almost the 

 appearance of a little blunt horn on the top of the puparium. 



The pellicles are by no means always centrally situated, and, 

 if regard were had only to the female puparium, one might con- 

 sider the insect as a Diaspis. But the male puparium is very 

 certainly smooth and not carinated, and consequently the 

 species must remain attached to Asiyidiotus.
