This species closely resembles T. spinicollis Horv. in the structure of the 
head and paranotal spines, also in colour. It differs, however, in the angulations on 
the lateral margins of the elytra. These vary somewhat in development : in some 
specimens they are just discernible, w r hile in others they are very distinct and 
spinose. 
Tingis (Tingis) insularis n. sp. 
(Plate XXXIV, figure 10.) 
Very similar in general appearance to T. angulata , but differing in the 
following respects : — Costal membrane wider with two rows of areolae ; lateral 
margins of elytra and the carinae, minutely denticulated, the denticules bearing 
a fine hair ; femora and tibiae furnished with scattered erect hairs ; the three 
paranotal spines are all anterior to the lateral angles. Colours similar to T. angulata, 
but the transverse fascia and other brown markings are generally paler and less 
defined. Length 2*625 mm. ; breadth 1 mm. 
Holotype. — Dunk Island. N.Q., August (F. A. Perkins). He. 3368. 
RADINACANTHA n. gen. 
Elongate-ovate, with long and slender legs and antennae. 
Head nearly as long as wide, convex above, with five long slender spines ; 
the four outer ones directed upwards and outwards, the central spine is nearly 
perpendicular ; bucculae prominent, extending beyond head, rounded and closed 
in front, reticulated ; antennae long and slender, segments 1 and II moderately stout, 
cylindrical, the second a little shorter than the first ; III very long, filiform ; IV 
longer than the first and second conjoined, slightly swollen towards apex, and clothed 
with a few fine hairs ; rostrum short, reaching barely halfway between the first and 
second pair of coxa?. Pronotum with one central carina, which is percurrent ; disc 
strongly convex, coarsely punctured, nitid ; hood absent; collum deep, slightly 
raised anteriorly ; paranoia narrow anteriorly, obsolete posteriorly ; posterior 
angle depressed and reticulated ; rostral sulcus open behind ; odoriferous orifice 
present. Elytra narrow, much longer than the abdomen, sides slightly sinuate ; 
costal membrane uniseriate, areola? tetragonal, large ; costal area uniseriate, areolae 
also tetragonal, increasing in size posteriorly ; the discoidal area extends half the 
length of the elytra, and is widest before the middle, with five-six rows of small sub- 
circular areolae-* Legs very long and slender, femora slender basally, slightly swollen 
towards the apex. 
Type. — R. reticulata n. sp. 
This genus is chiefly distinguished by its outwardly directed head spines, 
single pronotal carina, uniseriate costal membrane, and costal area. 
Eadinacantha reticulata n. sp. 
(Plate XXXIV, figure 11.) 
Head sparsely punctured, nitid, armed with five long slender spines, the 
four outer ones extending outwardly beyond the sides of the head. Pronotum with 
distinct uniseriate paranota, which are convexly curved from the base of the collum 
and disappear at about the middle of the lateral margins ; the pronotal carina is 
also uniseriate, areolate.
