The only other vein (the median) is given off at about one-sixth the length of the 
wing, and extends out into the disk a little more than one-half the wing length. 
There are, in addition, two white lines, one extending out from the fork of the sub- 
costal and the median nearly straight to the tip of the wing, and one from the base 
in a gradual curve to a point some distance below the tip. Near the base of the 
wing below is a small ear-shaped prolongation, folded slightly on itself, making a 
sort of pocket. The halteres are foliate, and furnished at tip with two hooks, which 
fit into the folded projection at base of wings. The abdomen is slightly hairy, with 
the joints well marked, and is furnished at tip with two strong projections, each of 
which bears at tip four long hairs and a few shorter ones. When the insect is at 
rest the wings lie flat upon the back." 
Larva (mounted) : About 0-6 mm. long. Antennae 6- jointed, about 
0*415 mm. long without terminal setae ; longest terminal seta about 
0-8 mm. long. 
Caudal extremity with 6 very long setae ; longest of which measures 
about 1 mm. The antennal segments approximate in fi : — (1) 40 ; (2) 
60; (3) 54; (4) 60; (5) 50; (6) 136. 
The marginal setae are more numerous than in any of the other 
South African species, but are shorter, averaging about 0*1 mm. 
The dermis has numerous scattered "rosette " glands. 
Habitat : On citrus, acacias, roses, etc., throughout the Union. 
Australian Bug was probably introduced into South Africa at Cape 
Town in 1872 or early in 1873. It was certainly present in the Botanic 
Gardens, Cape Town, in 1873. According to the Keport {I.e. 1877) it w^as 
observed in the village of Ookiep, Namaqualand, a few months after its- 
discovery in Cape Town, but strangely enough it was not seen in 
Stellenbosch until the end of 1876. In 1877 it was known to occur in 
Cape Town and suburbs, Simonstown, Stellenbosch (Mulder's Vlei),Paarl, 
Malmesbury, Wellington, Ookiep, Bredasdorp, George (Brak Eiver)^ 
Uitenhage, and East London. 
Mr. Eoland Trimen (I.e. 1877) states that the first specimens seen by 
him in Cape Colony occurred in 1873, at Claremont, on blackwood (Acacia 
melanoxylon) obtained from the Botanic Gardens at Cape Town. He 
states : "In the course of a few months the insect increased so prodigi- 
ously in number, and the Australian acacias became so laden with them 
to such an extent that in the early part of 1874 the large blackwood-trees 
in the gardens, which were infested to a greater extent than any other 
plant, had to be cut down." The plants to which the insect had spread 
up to 1877 were given as follows : Acacia melanoxylon, Australian acacia, 
golden willow, Casurina, Fittosporum, blue gum (rarely), Australian 
" bottle-brush," oak, orange, vine, fig, Laurustinus, rose, rosemary, 
strawberry, verbena, plumbago, Indian jasmine, bougainvillea, hawthorn, 
poinsettia, and hakea.
