and thoracic segments very wrinkled, a deep angular brownish 

 cavity is evidently the mouth, which is retracted when the coccid 

 is removed from the gall ; when in the gall it is attached to the 

 roof of the chamber ; short, cylindrical, 2-jointed fore and middle 

 legs ; hind legs ferruginous, femora short and stout, tibiaj stout, 

 tarsal joint about twice the length of femora, tapering slightly to 

 the tip, which is rather rounded and not truncate at the apex. 

 Hah. — Bendigo, Vic, on Eucalyptus sp. (Froggatt). 



The galls of this species are very like those of 0. siihrotunda, 

 but the remarkable well-developed antennae and curious serrate 

 edges of the segments make it very distinct from any other species 

 I have examined.
