OTARIS AURITUS,* n.g. and n.s. 
(Plate LIX. figs. 1, la.) 
Supraliumerals strongly divergent. Pronotum very short, as also is the posterior 
horn, which is almost obsolete. General form of the insect deltoid, or triangular. 
Tegmina dense brown. In appearance it somewhat recalls Hoplophora concisa , but 
the short pronotum well exposes the scutellum. The posterior horn is blunt, and is 
much shorter than the broad abdomen. The colour dense brown with punctuation. 
The legs also quite differ from the genus Hoplophora. The supraliumerals are blunt 
when viewed from the back, but acute and set at right angles as seen from the front. 
A comparison with Platycentrus obtusicornis also leads to the conclusion that the 
insects are quite distinct, which in a measure is borne out by their different habitats. 
It is not represented in the B.M. Collections. 
Size, 8x4 mm. 
Habitat .—Sumatra (Janson). 
Genus : TRICOCEPS, n.g. 
Distinguished by its high metopidium, the breadth between the supraliumerals, 
its curved posterior horn without an inferior node, and by the hirsute clothing of the 
body. 
TRICOCEPS BRUNNEIPENNIS. 
(Plate LYI. figs. 8, 8a.) 
Small, brown, hirsute, flat between the supraliumerals, with the eyes large. 
Posterior horn stout, without sinuation, free above the scutellum. Two white 
patches occur, one on each side above the tegmina, and two additional spots below 
them. The legs are yellow and very pilose. The tegmina hyaline short, with 
brown at their bases, with corrugated membranes, bounded by coarse yellow 
neuration. 
Size, 5x4 mm. 
Habitat. —Natal. 
Genus: OPHICENTRUS. 
Fowl. l.c. p. 15G. 
May be known by the peculiar serpentine form of the posterior horn. The 
tegmen has five apical and two discoidal areas on the corium, as shown by the type 
insect following.
