Subfamily TINGITINiE. 
Tigava unicarinata n. sp. 
(Plate XXXII, figure 2.) 
Elongate and slender. Head smooth, nearly as long as wide, armed with 
five spines . two basally at sides depressed, parallel, nearly reaching to the base 
of antenna? : between these anteriorly are three shorter semi-erect, spines in a triangle, 
the anterior pair slightly divergent ; antennal segment I four times longer than the 
second. Ill very long and slender, four and a-half times longer than the first ; 1\ 
about as long as the first, fusiform and clothed with short hairs ; rostral sulcus 
circular behind ; the rostrum reaches halfway between the anterior and intermediate 
coxa 1 . Pronotum coarsely but shallowly punctate, reticulate on the posterior angle 
which is long and acutely pointed ; anterior margin truncate : lateral margins 
anteriorly narrowly carinate : median carina percurrenl ; lateral ca rinse absent ; 
disc moderately convex. Elytra long, constricted slightly beyond the middle, 
widening and rounded posteriorly : the areola? are small and rounded, slightly larger 
on the sutural area apically ; costal membrane very narrow, carina-like ; costal area 
b iseriate, triseriate at apex of discoidal area ; discoidal area with about seven 
irregular rows of small areolae ; wings much longer than the abdomen. 
General colour pale yellowish brown with darker brown markings. Head 
testaceous brown, the three anterior spines concolorous ; the basal pair, pronotal 
carina, lateral pronotal margins, a longtiudinal stripe on disc at each side of the 
median carina, the posterior angle apically and the buccuke, whitish ; the inner 
anterior discoidal border, a narrow interrupted fascia at apex of discoidal area, and 
a large triangular suffusion on the sutural area reaching to the outer border apically, 
reddish brown ; antennal segment I, orange ; segment IV, black ; segments II 
and III, and the legs, testaceous ; eyes ruby. Length 4*125 mm. ; breadth -S75 mm. 
Holotype . — Gold Creek, Q., May (H. Hacker). lie. 3361. 
Urentius sarinse n. sp. 
(Plate XXXII. figure 3.) 
Head small, armed with five slender spines, two basally at sides, one submedial, 
and two in front ; antennae rather short, thinly setose and widely separated at 
the base ; segments I and II about the same length, short and stout, moniliform ; 
III cylindrical, twice as long as the fourth ; IV longer than the first and second 
conjoined, swollen towards the apex. Pronotum broad, reticulated ; triearinate on 
the posterior angle ; disc moderately convex, with strong irregular carinations 
enclosing three lateral foveate areas ; the inner boundaries to these areas form fairly 
straight carina?, subparallel to the median carina : all the carinae, also the lateral 
margins of pronotum and elytra, are armed with long slender spines ; hood small, 
sharply carinate above and projecting over the base of head. Elytra sinuatelv curved 
outwards from the base to their greatest width ; sides nearly straight and narrowed 
posteriorly ; the discoidal area is obliquely divided by a branch from the outer 
margin ; costal area biareolate, the areola? small, about the same size as those in the 
discoidal area ; costal membrane mostly biareolate, but uniareolate towards the 
apex, the areolae rather large. 
General colour pale ochraceous brown; a few spines and nervelets crossing 
the discoidal area at the middle, a few at the aj3ex, and the base of the posterior 
angle narrowly, fuscous ; head, body beneath and the tarsal claws, black ; the
