SCALE INSECTS (" COCCID^ ") OF AUSTRALIA. 55 



potash, very convex, longer than broad, often slightly depressed behind; 

 the margins tucked well under the body, but the ventral centre open. Length, 

 V',T of an inch. 



The male test is a pale dull yellow, elongate oval, the dorsal surface with a 

 fine dorsal carina, but the whole test finely ribbed with transverse ridges; 

 anal portions arcuate. Length -^ of an inch. 



Adult female before egg-laying evidently filling the test, much shrivelled 

 afterwards, reddish brown ; very convex beneath, with the derm thickened, 

 covered with many fine indistinct figure-of-eight pores ; broadly oval, no legs ; 

 antennae eight-jointed tapering to the tip, first three joints unifoim; 4th 

 shorter, 5th and 6th longer, 7th short, terminal one irregularly rounded anal 

 segment lobed on either side, with the anal plate almost enclosing the anal 

 ring, which is encircled with a fringe of about twelve long slender hairs. 



Lecaniodas'pis dilatata, n.sp. 



The tests are formed singly on a slender twig of Acacia discolor, and the 

 action of the female coccid causes not only a shallow depression to form as'in 

 the bark, but the twigs swell out and thicken wherever the coccid locates 

 itself. It is a rare species, but Mr. T. McCarthy (Assistant to Entomologist, 

 Department of Agriculture), collected several specimens on the wattles at 

 National Park, near Sydney, New South Wales. 



The adult female forms a slightly convex, flattened, shield-shaped, light 

 brown, granulated, waxy test, longer than broad, the sides irregularly parallel 

 with the extremities rounded; the anal aperture oval, close to the anterior 

 margin, with the test thickened and reddish brown round the opening. 

 Length, i of an inch. 



The adult female is a dark reddish brown, convex on the dorsal surface, 

 with the hind segment deeply arcuate, showing two tufts in the centre (in 

 potash these melt away). Length, ^ of an inch. In potash, broadly oval 

 with anal cleft moderate, the whole surface covered with scattered slender 

 spinnerets and pores. Antennse six-jointed, short, thickened, 3rd joint 

 longest, terminal one small irregular, tufted with two long hairs and a num- 

 ber of shorter ones; feet aborted; anal plates broad chitonous, anal ring 

 with apparently ten hairs.

The type specimens were found upon the bark of an undetermined species 

 of Eucalyptus at the western township of Whitton, New South Wales. 



The adult female forms a felted yellowish-brown waxy test, rather com- 

 pact, flattened, sub-circular, and resting in a depression on the bark, with a 

 small orifice in the posterior region. Diameter, Va inch.
