NEW SPECIES OF COCCIDAE FROM AUSTRALIA. 



49 



Adult female elongate, narrowed in front, broadest across the abdominal area ; 

 lateral margins of abdominal segments moderately protuberant. Pygidium (fig. 7) 

 with two prominent, obscurely tricuspid median lobes, and a single small but 

 prominent lateral lobe on each side, about half the breadth of the median lobes. 

 The most conspicuous feature of the pygidium is the series of broad semilunar 

 marginal pores, one between the median and lateral lobes and others, in pairs, at 

 intervals along each side of the pygidium. Each of these marginal pores gives rise 

 to a conspicuous broad flat plate, the free edge of which may be pointed, rounded, 

 or obscurely serrate, and in the interval between the pairs is a complex marginal 

 prominence, which appears to consist of narrow finger-like processes overlying 

 each other. Circumgenital glands in five groups ; median group small, 2 to 4 pores 

 only ; upper laterals, 12 to 16 ; lower laterals, 15 to 23. Dorsal oval pores large 

 and conspicuous, in interrupted series. Length, 1-25 to 1-75 mm. 



Length of nymphal pellicle, 0*75 mm.

Froggatt has recently described, as Chionaspis eucalypti, a species which must 

 be referred to my Ch. angusta, described in the Victoria Naturalist (xxi, p. 67) in 1904. 

 I must myself accept the responsibility for this mistake, as Mr. Froggatt submitted 

 his specimens to me for determination, and I failed to recognise them at the time. 

 The examples on Eucalyptus are distinctly larger, and the puparia more dilated, 

 than are the original specimens from Leptospermum ; but the structural characters 

 of the insect are typical. 



Fresh material received from Mr. French. (No. 74) show the typically narrow 

 puparia, which are, in these examples, overlaid by a considerable quantity of loose 

 flocculent white secretionary matter, disguising their true form.
