REMARKS ON COCCIDAE FROM NORTHERN AUSTRALIA — II. 



61 



four on each side, the one nearest the extremity minute and spiniform, the two nearest 

 the base broadly expanded and externally sinuate. Dorsal oval pores few. Circum- 

 genital glands in five groups, the number of pores unusually constant, median group 4, 

 u^per laterals 6, lower laterals 4. Length 075 mm. 



On Melaleuca leucadendron, Stapleton, N.T. (Hill, 635). Heavily attacked by 

 a red parasitic fungus. 



In the peculiar structure of the pygidial margin, this insect approaches Chionaspis 

 oinnamomi, mihi ; but in that species the median lobes, though closely approximated, 

 are distinctly divided, and cinnamomi is without circumgenital glands. 



Leucaspis japonic^ var. darwiniensis, no v. 



Female puparium dull brown, thinly overlaid with whitish secretion. 



Male puparium white ; rather convex, not carinated. 



Nymphal pellicle (fig. 8, a) coarsely granulose. Posterior extremity (fig. 8, b) 

 with four sharply tricuspid lobes. Length 1 to M5 mm. 



Fig. 8. Leucasins japonica var. darwiniensis, var. n. ; a, nymphal pellicle, x 65 ; 

 0. posterior extremity of nymph, x 280 ; e, adult female, X 65 ; d, pygidium of female, 



X 450. 



Adult female (fig. 8, c) slender, before gestation ; later contracted and propor- 

 tionately broader. Two sinuous longitudinal series of minute conical points on the 

 venter, embracing the rostrum and extending downwards to near the base of the 

 pygidium. Anterior spiracles with a small group of four or five parastigmatic pores.
