Hah. — Sydney (on Eucalyptus sp. ; W. W. Froggatt) ; Port 

 Macquarie (on Eucalyjitas sp.; Mr. G. R. Brown). 



SPHiEROCOCCUS FERRUGINEUS, n.sp. 



(PL IX., figs. 16-20.) 



9. Coccid dark reddish-brown on the dorsal surface, dull yellow 

 on the ventral surface; length 11 Hnes : ventral surface flat; 

 circular ; dorsal surface conical, with the anal tip showing an 

 elongate oval mark. 



9. Gall varying from dark reddish-brown when full grown to 

 pale green when immature, 10 lines in diameter. Ball-shaped, 

 formed by a number of leaf-like bracts springing out from the tip 

 or side of a twig. The coccid imbeds itself in the tip of the twig, 

 the head being attached to the tissue which rises up on either 

 side, forming a regular cleft The central gall commences as a 

 woody excrescence on the leaf bud in which the coccid is half 

 imbedded, the tissue rising up over the coccid into a loose thin 

 shell. 



The leaf-like tufts forming the outer portion of the gall are 

 each composed of a number of smaller bracts springing from a 

 common centre like flowerets, forming a regular loose rounded 

 mass. When this gall is produced upon the tip of the twig it 

 contains a single coccid, but if it grows out on the side of a twig 

 it often shelters two. 



(J. Coccid unknown.
