Adult female yellowish brown, smooth, shining, elongate, much longer 

 than broad, rounded at the extremities, convex. On some plants this species 

 becomes much broader, and resembles L. hesperidum in general form, but 

 typical specimens are long, slender, and semi-cylindrical. It can be distin- 

 guished from the former by the long stout eight-jointed antennae, and the 

 derm cells being nearly twice as numerous. In L. hesperidum the antennae 

 are seven -jointed. Length, i inch. Maskell described his species from Fiji 

 upon the same food-plant (custard apple).

This fine species was collected upon ti-tree {Melaleuca sp.) bushes growing 

 on Palmer Island, Clarence River, New South Wales. 



In a list of the coccidae of Massachusetts, King lists this species as one 

 introduced into the United States upon Monstera deliciosa, growing in a hot- 

 house at Harvard University. If his identification is correct, it is a most 

 remarkable instance of a rare Australian coccid (only recorded from the one 

 locality) being introduced on a hothouse plant. 



The adult female is reddish brown, slightly convex, tapering behind, with- 

 out distinct dorsal carinas ; epidermis, slightly rough, with minute pustules ; 

 sometimes the dorsal surface is ornamented with white, waxy tufts. Length, 

 from i to T inch. 



The male puparium forms a thin, glassy test, with the centre covered with 

 additional snow-white, waxy secretion. Length, yi inch.

The type specimens found on the foliage of the " Weeping Myall '" {Acacia 

 pendula), growing in the Mallee Scrub, North-West Victoria. 



Adult female dark brown to yellowish brown, very convex, with a flattened 

 broad margin right round. At the apex of the dorsum there are two rows 

 of rather deep subcircular pits, varying from four to six in number. The 

 abdominal cleft normal, with the dorsal lobes small. Length, up to ^ inch ; 

 width, ^ inch ; and height, J inch. The immature coccids are finely granu- 

 lated on the dorsal surface, numerous yellow spots showing through the 

 uniform brown coloration. 



The large size of the adult female, with the distinctive pits in the centre 

 of the back, and the broad, marginal flange, gives it a very distinctive 

 character.
