Genus : SEXTIUS. 
Still, Hem. Afri. iv. p. 88. 
The form variable, but never with the horns compressed, either from behind or 
before. Thorax furnished with a longitudinal carina. Lateral horn three-cornered. The 
posterior horn tectiform, and hollow below. The scutellum not, or only slightly, promi- 
nulous. Apical areas of the tegmina divided by several anastomosing short veins (Stal). 
SEXTIUS CUPREUS. 
(Plate L. figs. 8, 8a.) 
Centrotus cupreus , Kirb. Jour. Lin. Soc. p. 1G8 (1891). 
Small, with a copper-like lustre in an oblique light, but dull greyish in other 
lights. Pronotum with two sharp but short suprahumerals clothed with fine hair, 
and with a long posterior horn. The thorax and the lower part of the frons and 
under the wing-insertions white. Tegmina dense and greyish-ferruginous. Neuration 
somewhat abnormal, as there appears to be only one discoidal area, and the apicals 
are long and curved. Legs moderate in length. 
Size, 5x3 mm. 
Habitat .—Ceylon.

SEXTIUS VIRESCENS, Fairm. 
(Plate LI. fig. 3.) 
Fairm. Centrotus virescens, l.c. p. 515. 
Small, rather obtuse. Pronotum with conical, but not very obvious supra- 
liumeral processes. Metopidium square, with the frons broad between the eyes. Pro¬ 
notum narrows rapidly from the dorsum to the posterior apex. Whole body fulvous 
yellow, except the abdomen, which is sordid green, punctured with fine dots. Legs 
reddish, with flattened tibiae. Tegmina hyaline, rather short, with yellow neuration, 
and with reticulated apical cellules. The scutellum is partly hidden. As the 
specific name indicates, the insects are green whilst living. 
Size, 7x3 mm. 
Habitat. —Melbourne, Adelaide, Australia, Tasmania.

Genus : CERAON, n.g. 
The characteristics of this genus, and by which it may be distinguished from 
Daunus, are the truncated and broadly flattened extremities of the suprahumeral 
processes. These are carinated. The posterior horn is long, acute, somewhat 
curved, and free above the abdomen. The tegmina show a tendency to develop 
short transverse veins from the radials.
