Genus ARESSIDA Cameron. 
1. ARESSIDA ANNULICORNIS Cameron. Female. Genotype. 
Length to end of ovipositor, 12 mm. 
Dark bronzy red tinged with green; on top, the pleure and sternum blue, more or 
less tinged with indigo above, the upper part of the meso- and the metapleure purple, the 
basal four dorsal segments of the abdomen fiery red; the apical, the sides and ventral sur- 
face dark purple; the sides of the second to sixth above with emerald green spots; that 
on the fourth longish, oval, extending from the top to the bottom, much larger than the 
others; these spots are densely covered with silvery pubescence. Legs red, coxe to near the 
apex blue, tinged with violaceous, hind coxa with a fiery red spot on the apex above; apex 
of the fourth front femora, the hinder for the greater part and the base of the tibiz, dark 
bronzy green and blue; knees pale testaceous. Wings hyaline, venation dark fuscous; a 
longish pyriform cloud at the end of the submarginal vein and touching it, the narrowed 
end in front; a smaller transverse, triangular cloud beyond it, a much larger cloud at and 
touching the stigmal vein, narrow at it, commencing near the base and extending a little 
beyond its apex; thence it becomes gradually roundly widened, more so at the base than at 
the apex. Head behind the ocelli with fine, close, rounded transverse strie, below with 
stronger longitudinal striw, the strie more or less obliqued. Malar space as long as the 
eyes; a fine furrow down its center. Eyes converging above, separated there by the length 
of the fifth antennal joint. Anterior ocellus larger and paler than the others and separated 
from them by double the distance these are from each other. Pro- and mesonotum and 
scutellum closely covered with roundly curved strie; those on the base of the pronotum stronger 
and more widely separated than on the rest; apex of scutellum with a rounded projecting - 
border. Metanotum smooth, the centre with stout diverging striw, the outer longer than the 
inner; the sides densely covered with silvery pubescence. Abdomen shining, smooth; the 
basal two segments larger than the others; not much longer than wide. Third and fifth 
longer than wide, sixth still longer, of equal width, tubular; beyond it is a much longer 
segment above and closely pressed to the ovipositor, which is broad, of equal width and 
projects one third of its length beyond it. Smooth keel down center of pronotum; its apex 
becomes gradually widened from the middle. Seutellum obliquely narrowed at the base, which 
is transverse and one fourth the width of the broadly rounded apex. Mesopleure above the 
furrow closely, regularly reticulated, below vertically, more or less obliquely striated, as are 
also the metapleure, the basal (and larger) part more strongly so. Parapsidal furrows 
distinct, curved. The fore and posterior femora are thickened, the anterior with a curved 
incision on the lower part of apex; the middle thinner and narrowed at the apex. There are 
some longish, scattered white, weak spines on the hind tibizw; the tarsi have shorter and more 
numerous spines; the shorter spur of the hind tibie is longer than the width of the apex of 
tibie. 
Habitat: Gosford, New South Wales. 
Type: Query. 
2. ARESSIDA NIGRICORNIS Cameron. 
-* Length, 6; terebra, 2 mm. 
Belmore, near Sydney, N.S. Wales (F. Taylor).’’ 
The difference between this species and A. annulicornis may be shown thus:— 
Antenne entirely black, the knees not pale, the basal cloud in fore wings of equal width, 
the apical not roundly curved and narrow, its base oblique; the upper part of ovipositor 
shorter than the preceding two segments united, longer than the apex of the projecting 
lower part .. be ae ae ot 5 ae 50 ae oie nigricornis.
