MEMBRA C1DJE. 
CENTROTYPUS TIBIALIS, Dory. 
(Plate LIV. figs. 3, 3a.) 
Centrotus tibialis. 
Smaller, with the suprahumerals arcuate and pointed instead of dilated. 
Posterior horn sharp and projecting far beyond the abdomen. A white tomentose 
patch occurs in the region of the scutellum. Abdomen ringed and sordid oclireous 
in colour. Legs yellow. Tegmina with broad dark fuscous costal areas, dark brown 
neuration and a corrugated limbus. Wings delicate, and hyaline. Metopidium high 
and very pilose. Suprahumerals short, divergent, and not flattened. 
Size, 8x4 mm. 
Habitat .—New Guinea. 
CENTROTYPUS SECURIS, n.s. 
(Plate LIV. fig. 4.) 
The pronotum is broadly expanded between the suprahumerals into an axe-like 
form, which with the pointed posterior process suggests a pickaxe. The insect thus 
appears as broad as it is long. The pronotum quite conceals the legs from the view 
above. 
The colour blue-black, glabrous, the horn deeply punctured, but with strong carinal 
edges. Tegmina sordid oclireous. 
By the front view the suprahumerals are thin and divergent. 
Size, 11x7 mm. 
Habitat —Burma. 
This description does not agree with Centrotus malleus or with C. malleator of 
Walker. 
CENTROTYPUS ATER. 
(Plate LIV. fig. 5.) 
Whole pronotum dull black. Suprahumerals stout, broad, acute, and slightly 
recurved. Pronotum quite covers the abdomen and legs. Tegmina with thick brown 
nervures with the costal areas brown, and each with a dark triangular spot at the 
basal margin; the membrane otherwise is hyaline. The pronotum is arcuate in 
front, but allows the head and eyes to be visible above. 
Size, 14 x 11 mm. 
Habitat .—Ruby Mines, Burma.

Genus : IBICEPS, n.g. 
Characterised by long, erect, suprahumeral processes, which are markedly reflexed 
at their tips, at an angle. The posterior horn, though distant, is not elevated above
