This species differs from £. 32-guttata, Serville, by the elytra 
being much more suddenly contracted beyond the middle; the 
colours of the marginal space, the greater number, disposition 
and intensity of the guttz, the different curvature of the first 
radial branch and the colour of the antenne. After death the 
body, legs, and parts of the elytra become more or less brown, 
and in alcohol the whole insect assumes a pale testaceous tint, 
except the dark spots. 
The insect feeds on the Australian Cyprus Pine (Callitris 
verrucosa), and is but seldom seen. The three specimens in the 
Adelaide Museum were obtained at Monarto and Sandy Creek. 
At the former locality the writer captured three specimens close- 
‘together on one tree in 1872. 
Genus EPHIPPITHYTOIDEA, gen. nov. 
Fastigium of vertex terete, not much depressed, sub-contiguous 
with the frontal. Face moderately long, much retracted, slightly 
sulcate laterally, carinate about the eyes. Pronotum saddle- 
shaped, constricted, disk rounded posteriorly. Defiexed lobes 
roundly-inserted in front and angular behind, and distinctly 
suleate. Elytra narrow-linear, hindmargin concave, nearly of 
equal width throughout, apex rounded; radial veins contiguous 
for some distance beyond the first radial branch; the latter is 
emitted slightly before the middle and forked towards its 
extremity ; anterior ulnar vein parallel with radial branch emit- 
ting four branchlets to hindmargin. Transverse veinlets much 
raised, numerous, oblique, and closely reticulate. Tympanal 
area small, veins very strong, and a speculum in both elytra of 
the male. Wings as long as the elytra, apex rotundate. Fore 
and middle femora near apex with a few small spines and 
distant short hairs, hind femora armed nearly to the base, knee- 
joints with long spinose lobes, basal part very much incrassated, 
apical part very slender. Fore tibie with rimato-conchate 
foramina on both sides, terete above, posterior margin spined. 
Meso- and meta-sternum with short broad lobes. Supra-anal 
lamina of males deflexed between the hairy cerci; latter stout, 
bilobed at apex. Subgenital lamina in two lobes very thick in 
the middle, styles not apparent. Female unknown. 
This genus differs from all others by the subtriangular lobes of 
the pronotum, the latter being convex above, besides many other 
distinctions. In general appearance, however, it resembles 
Ephippithyta so much that a superficial observer may easily 
mistake it for a smaller variety. 
EPHIPPITHYTOIDEA SPARSA, Sp. 110U. 
Dusky yellowish varied with grey and blackish dots, &c., 
shining. Face black, the labium, a long wedge-like stripe
