PoUanisus ? rufiventris. (Plate VI. fig. 7.) 
Procris rufiventris, WalTcer, Cat, Lep. Het. i. p. 110. n. 11 (1854). 
Wings purplish brown. Head, thorax, base of abdomen, and anus black ; remaining 
segments of abdomen reddish orange. Expanse of wings 7 to 9 lines. 
Swan river, Australia. 
I am rather doubtful as to whether this should not form the type of a new genus, the 
pectinations of the antennae in the male being shorter than in the other species. 
Mr. Walker gives 4 lines as the measurement of the wings ; but this must be a misprint, 
for the smallest example in the Museum, when measured from tip to tip of the primaries, 
expands 6 lines. 
PoUanisus cupreus. (Plate VI. fig. 5.) 
PoUanisus cupreus, Wallcer, Cat. Lep. Het. i. p. 115. n. 3 (1854). 
Primaries metallic copper-colour, the apical area purplish brown ; secondaries dark 
brown. Head and thorax bright copper-colour ; antennae black ; abdomen blackish. Wings 
below purplish brown, fringe paler; pectus and frons cupreous. Expanse of wings 10 to 11 
lines. 
West Australia {Clifton), Swan river {Richardson) . 
NEUROSYMPLOCA, Wallengren. 
Neurosymploca contraria. (Plate VII. fig. 4.) 
Zygaena contraria, Walker, Cat. Lep. Het. i. p. 113. n. 18 (1854). 
Primaries semitransparent brown, with six small orange spots placed obliquely in pairs — 
the first pair at the base connected by a pale testaceous patch ; the second pair in the middle, 
also connected by a pale band ; the third pair subapical, not connected : secondaries crimson, 
with a very ii'regular black border. Body black, with an orange spot on each shoulder. 
Expanse of wings 11 to 14 lines. 
Natal {Gueinzius). 
A second example of this species was placed by Mr. Walker among the specimens 
referred to Zyg(Rna concinna, which unfortunate error has caused much confusion. Walker^s 
description of the body in Z. concinna is taken from an example of Z. hottentotta. 
SYNTOMIS, Ochsenheimer. 
Syntomis nostalis. (Plate VI. fig. 11.) 
(S . Syntomis nostalis, Wallcer, Cat. Lep. Het. i. p. 129. n. 28 (1854). 
$ . Syntomis simplex, Walker, I. c. n. 27 (1854). 
Blue-black ; primaries with five white hyaline dots, one at the base, two in the middle, 
and two before apex : secondaries with a small white spot on interno-median area near the
