West Australian Coccidie. 447 



galls collected, many had been eaten into by Sigastus 

 fascicularis, Pasc, and in several cases the beetle was 

 found hiding in the chamber of the gall. In every instance 

 an entrance had been made at the apex of the gall, where 

 the wall is thinnest ; from the circumstances under which 

 the beetles were found, there is no doubt that they sought 

 the Coccid. Swan River, W. A.

 simple. The hinder margins of the segments are fringed upon the 

 dorsum with a row of sharp, thorn-like spines, and the median region 

 of the whole of the dorsum is densely clothed with short, stout,

9 gall, bright green, narrow at the base and widest near the apex, 

 sessile or shortly stalked ; summit truncate, with a central cone 

 rising from it, the point of which is perforated by the small entrance 

 to the chamber. Usually 4 — 5-sided, with prominent longitudinal 

 ridges at each corner extending from the base up, and ending abruptly 

 with the summit. Length 1 to 1^ inch. The twig to which the gall 

 is attached is always much swollen around its base, so that the gall 

 grows from a small pit. $ chamber elongate, almost fusiform, the 

 widest portion being toward the apex. 



Immature $ galls sessile, somewhat pyramidal, swollen at the 

 base ; apex conical ; sides strongly ribbed ; orifice closed. 



(J gall growing upon the leaves, cylindrical, longitudinally ribbed ; 

 summit dilated, and deeply serrate ; colour light yellow. Length ^ 

 inch.
