This is our largest dull-brown Lecanium, common on the graje vines, 

 oiiginally described from France. It was discovered in Victoria on vines, 

 and doubtfully identified by Maskell in 1897 as this introduced scale, and he 

 confirmed his determination in the following year. Until the last few yeais 

 it was unknown in New South Wales, but at the present time it is very com 

 mon in the vicinity of Sydney, and is spreading in our vineyards. 



Adult female, reddish brown, slightly mottled with a darker tint, elongate. 

 bioad in proportion, very convex, slightly rugose on the back, with a shoit 

 keel behind the anal cleft. The form is, however, very irregular when massed 

 together; encircling the vine cane, they are much shorter and more rounded, 

 and the margins are more impressed than in an isolated specimen. Length. 

 ^ inch, width up to i of an inch. 



Treated with oil, the derm appears to be mottled reddish brown and yellow 

 central portion shield-shaped, irregularly marbled, encircled with a dark 

 ring, with the outer edge yellow. 



Newstead, in his description of Lecanium persiccB, says : " With regard to 

 L. herheridis, L. rugosum, and L. westerice, I have little doubt in my own 

 mind that they are also referable to L. persicce." If Maskell's determinations 

 of the two species are correct, his L. persicw and L. herheridis are certainly 

 distinct species.

Lecanium cappari, n.sp. 



A western scale, common on the foliage of the " Wild Orange Bush " 

 (Capparis mitchelli), wherever this prickly shrub occurs in the western scrubs 

 of New South Wales. The adult female is a dark chocolate brown, with the 

 edges lighter coloured; broadly rounded, convex, with the margins narrow, 

 but finely crimped along the edge, and a short transverse carina on either side. 

 Often variable in form, with the anterior portion constricted, so that the 

 posterior portion is more broadly rounded and depressed below the anal 

 orifice. The dorsal surface is opaque and covered with a fine waxy secretion. 

 Length, i of an inch. 



Treated with oil, the whole of the central area is an elongate oval fhield 

 with egg-shaped structures pointing outward, again encircled with a band 

 of fine tesselated markings and the margin perfectly clear. 



In the immature females the coloration is much lighter, with the margin 

 yellow, and the form more elongate oval, with a slight dorsal caiina. Male 

 tests white, semi-transparent, elongate oval, flattened, with a white line on 

 either side, converging to a point at the posterior angle. Lateral plates finely 

 crenulated on the margins. Length, -i\f of an inch.
