REMARKS ON COCCIDAE FROM NORTHERN AUSTRALIA — II. 55 



and lateral lobes, two or three just outside the lateral lobe, and one or two beyond 

 the outer pair of paraphyses. Spines rather large and more conspicuous than the 

 squames. Paraphyses clubbed, large and conspicuous ; two pairs on each side, the 

 inner pair longest, arising from the interval between the median and lateral lobes, 

 the outer pair arising from an indentation at a short distance beyond the lateral 

 lobes. Anal orifice very small, near the extremity. No circumgenital pores. A 

 transverse series of chitinous thickenings across the base of the pygidium. Length 

 approximately 0-75 mm. 



On the upper surface of leaves of Ficus orbicularis, Darwin, N.T. (Hill, 23). 



This insect is a true " mining scale," the puparium being completely covered by 

 the actual cuticle of the leaf. The peculiar paired and clubbed paraphyses sufficiently 

 distinguish the species. 



PoROGYMNASPis, gen. nov. 



Female puparium consisting of the enlarged nymphal pellicle, w^ith or without a 

 superimposed larval pellicle, but without any secretionary appendix or covering. 



Male puparium with an oval or oblong secretionary appendix, with the larval 

 pellicle situated at the anterior margin. 



Posterior extremity of nymphal pellicle with prominent lobes, broad fimbriate 

 squames, and conspicuous semilunar marginal pores, as in Parlatoria and Leucaspis. 



Adult female entirely enclosed wathin the nymphal pellicle. Pygidium with 

 circumgenital pores ; posterior margin with small lobes and cuspidate marginal 

 processes. 



The characters of the genus associate it with Gymnaspis, Parlatoria and Leiicuspis. 

 It is probably most nearly related to Leucaspis. 



The genus differs from Gymnaspis in the presence of circumgenital pores ; from 

 Parlatoria in the enlarged naked nymphal pellicle which completely encloses the 

 adult insect, and in the absence of semilunar marginal pores on the adult female ; 

 and from Leucaspis in the total absence of any secretionary covering or appendix 

 to the female puparium. 



Porogymnaspis rufa, sp. nov. 



Puparium of female consisting of the naked nymphal pellicle which is bright red 

 or reddish yellow, broadly oval, highly convex, appearing almost hemispherical to 

 the naked eye, but showing (under a lens) a profile as represented at figure 3, a. The 

 larval pellicle is shed at an early stage of growth. The pygidial area is sharply defined 

 (fig. 3, c) and occupies an almost erect position at the posterior extremity of the 

 pellicle ; its margin bears eight prominent but slender lobes, the median and first 

 laterals obscurely trilobed, the second laterals obscurely indented on the outer edge, 

 the third laterals simple. Squames broad, obscurely tricuspid at extremity. 

 Conspicuous semilunar pores, three on each side. Length 0-75 mm. 



Male puparium (fig. 3, b) oblong or broadly oval, moderately convex, sometimes 

 with traces of two longitudinal ridges, whitish ; the small fulvous pellicle placed 

 close up to the anterior margin. Length 0-75 to 1 nmi.
