(Plate XXVI. figs. 1, la.) 
Walk. //. bigutta, l.c. Suppt. p. 112 ; Fowl. l.c. Tab. VI. fig. 7, 7a, ? p. 78. 
Pronotum punctured, shining ochreous yellow, with a convex and sinuous dorsal 
ridge ; much depressed at the sides, with an obscure brown spot in the depression ; 
suprahumeral horns broad at their bases, obtuse, but pointed with black; tegmina 
rich sienna brown; legs ochreous yellow. 
By the dorsal aspect the suprahumerals are set at right angles, plane or hat., 
between them, and continuous with the metopidium. The tegmina with five apical areas-

HYPHINOE PURULENSIS. 
(Plate XXVI. figs. 2-2b.) 
Fowl. l.c. Tab. VI. fig. 1, lb, 5 fig- 5, 5a, 8 p. 77. 
Large ; rich dark brown, shining, punctured with a conspicuous ochreous stripe 
bounding the straight lower margin of the pronotum; dorsum straight without 
sinuosities; suprahumeral horn stout, pointed, acute and black at the tips; irons 
and metopidium dull ochreous, convex ; tegmina dark violaceous brown, punctured, 
yet very shining, and rather projecting beyond the tip of the pronotum ; legs dark 
ferruginous and rather short. 
Fowler describes this species, as having a conspicuous dark spot on each side of the 
pronotum. The example f figure from his private collection does not show these 
spots, but there are depressions on the disc which may represent them. My specimen 
is larger than the normal, so 1 conclude it to be a slight variety. In other respects 
it agrees with his diagnosis. 
The males are smaller than the females. Some varieties have outward resem¬ 
blances to the genus Ceresa. 
Size, 17x8 mm. ; 14 x 7 mm.

HYPHINOE PURULENSIS, var. ? 8- 
(Plate XX VI. figs, 6, 6a.) 
There is a much smaller insect in the Fowler Collection which differs somewhat 
from that here described, inasmuch as the suprahumeral horns are almost suppressed, 
and the pronotal disc has a conspicuous brown spot on each side. Added to this 
there is no marginal stripe.
