Maskell. — On Coccididas. 11 



Male piiparium whitish, shghtly elongated, smaller than 

 that of the female ; not cariuated. 



Adult female dark-brown, of normal peg-top form. Abdomen 

 ending in two not large rounded lobes, and perhaps after a 

 small interval another inconspicuous lobule on each side. 

 Margin slightly serratulate. No groups of spinnerets. 



Adult male unknown. 



Hah. In Australia, on Bossiea inocumhens : sent by Mr. 

 French. 



It is possible that A. ccddesii, Targioni, may be very near 

 to this species ; but the description of it is very vague, and I 

 see nothing in it indicating a soft woolly puparium such as the 

 Australian insect exhibits. 



Aspidiotus these, Maskell, sp. nov. 



The late Mr. Atkinson, of Calcutta, sent me in 1889 a 

 packet of specimens of a Diaspid on the tea-plant in the 

 Kangra Valley, Assam, India. I returned to him a description 

 and ligures early in 1890, under the name A. tliece, sp. nov. 

 I suppose that his lamented death, which took place in that 

 year, prevented him from publishing this paper : I understand 

 that it will appear shortly in " Indian Museum Notes." The 

 insect has a convex puparium, and its most striking character 

 is the presence on the dorsal abdominal region of the adult 

 female of a large and distinct patch of lattice-work pattern, 

 similar to that exhibited in Ischnasins filiformis , Douglas (Ent. 

 Mo. Mag., 1887, p. 21). 



Aspidiotus eucalypti, Maskell. Trans. Koy. Soc. South 



Austraha, 1887-88, p. 102. 



I have had specimens of this insect from New South 

 Wales, also on various species of Eucalyptus. I regret tliat 

 the figure Id, of plate xii. in the South Australian Trans- 

 actions, does not sufficiently exhibit the deep transverse groove 

 in the adult female, which is so marked a feature of it. 



Aspidiotus rossi, sp. nov. Crawford Coll. Plate I., figs. 



7-9. 



Female puparium normally circular, very slightly convex ; 

 colour a dull deep brown, almost black, sometimes fading into 

 a lighter shade at the edge : pellicles central, small, forming a 

 little boss which is sometimes yellowish. Diameter of pupa- 

 rium averaging about x^n., but varying a good deal. When 

 on narrow leaves the form is sometimes irregular, oblong or 

 elliptical. 



Male puparium slightly elongate, smaller and lighter in 

 colour than that of the female. 



Adult female of the normal peg-top form, dark-orange or
