4. RHIPIPALLUS AFFINIS Bingham. Male; female. 
Male :—Length, 5 mm. 
Head lenticular; clypeus triangular, deeply incised anteriorly; front below the antenne 
slightly raised, smooth and shining; cheeks, face and vertex finely but somewhat obsoletely 
longitudinally striate; scape of antenne short, smooth and shining; flagellum finely granulose, 
pilose, the hairs very short, the basal two joints simple, the rest except the apical joint with 
long slightly clavate rami on each side, two to each joint, apex distinctly incrassate. Thorax 
densely and somewhat coarsely punctured; scutellum conically produced, the apex terminating 
in two short teeth; at base a transverse series of fovee or large shallow punctures; post- 
scutellum and median segment very coarsely cribate, the latter with two or three irregular 
more or less vertical carine; wings hyaline and iridescent; legs slender. Abdomen smooth 
and shining, its petiole opaque grannlose. Mandibles, tibia and tarsi pale yellowish-brown; 
coxe and femora dark blue or black; antenne dark reddish brown; head, thorax anteriorly, 
scutellum and median segment, metallic green with in certain lights a bronze tint; middle of 
thorax above entirely coppery bronze; petiole and abdomen dark metallic blue. 
The female differs from the male as follows: Clypeus not incised; antennz moniliform, 
the joints simple not provided with lateral rami; scutellum not bidentate at apex, at base a 
deep, broad transverse sulcation within which is situated the transverse series of fovex sv 
conspicuous in the male; petiole of abdomen much shorter. Abdomen as in the male. Antenna 
paler, head and thorax more bronze than green; abdomen a darker blue. 
Habitat: Townsville, Queensland. July 30, 1902. Also in March and October. 
Types: In the Hope Department; cotypes in British Museum of Natural History. 
Superficially this form closely resembles the type of the genus (R. volusus, Walker) 
but besides other points of difference it is easily separable by the sculpture of the thorax 
which in volusus has the humeral angles of the thorax conspicuously smooth and shining, not 
coarsely punctured and no carinew on the median segment.
