33^, OS LT.\DI':SCKJHE1J SPECIES ()E .AJEMBKACiD.E. 



Fi". 3. Anrhuii. stilyatuni. The dorsal process is here free and uliiate. The procephalie point probably 



is cleft like that of the last-named species. Size 9x6 millimetres. 

 Fig. 4. Taloipa ttnctoria. The pronotum here is obtuse, and it ends posteriorly in a blunt process 



shorter than tlie abdomen. The bright orange colour on the base of the tegmina may be 



noticed. 



4 a. The hirsute frons with the square metopidium. Size 7x4 millimetres. 



Fig. 5. Leucothorax villosa. Large, with truncated but short dorsal processes. The chest lias a white 

 villous coat. 



5 a. The dorsal view of the pronotum. 



5 b. The frontal aspect of the insect. Size 1.2 x 6 millimetres. 

 Fig. 6. Leptocentrus impunctus. Remarkable for its long tegmina. 



6 a. The head and frons. 



6 b. The venation of the tegmen of the same. Size 10x5 millimetres. 



Fi". 7. Ophicentrus serpentarius. The undulating form of the dor.sal process has been used generically 

 by Canon Fowler, and I do so tentatively, whilst the immediate cause of variation in secon- 

 dary organs is sub judice. 



7 a. Frontal view of the insect. Size 8 x 4 millimetres. 



Fig. 8. Ibiceps rufpennis. The Imago. Bright shining, warm brown. The grey on the tegmina as 

 shown by this figure is only meant to represent the light glancing on the corrugations of the 

 wing, and it is not due to any patches of grey colour. Its long pronotal horn is smooth, 

 instead of rough as represented on the Plate. 



8 a. The head and front view of the pronotum. Size 8x4 millimetres. 



Fig. 9. Polocentrus caudatus. Tlie winged insect is somewhat remarkable from its short posterior 

 horn, which, like the rest of this genus, is serrated below. Legs spatulate. 



9 a. Front view with the short suprahumerals. Size 8x5 millimetres. 



Fi<^. 10. Polocentrus labatus. This insect is from Abyssinia, and has the characteristic serrated posterior 

 horn. 

 10 a. The front view with the dark frons and pointed suprahumerals. 



10 b. The tegmen with its dark fuscous venation which encloses the chief ochreous cellules. Size 



8x4 millimetres. 

 Fig. 11. Trapezoida hirsuta. This insect from Central America has a square metopidium which is 

 strongly hirsute. The dorsal view of the pronotum shows something of a lozenge shape. 



11 ffl. Head and frons of the same. 



116. Dorsal view of the insect. Size 7x4 millimetres. 

 Fi<^. 12. Larva of a Membracid, not uncommon in the neighbourhood of Cape Town, and at Wynberg, 

 S. Africa, but the winged insect has not yet been determined. The erect caudal nectary 

 discharges a liquid, probably of a saccharine nature, and gives the insect a grotesque appear- 

 ance. Probably it is visited by Ants, as is known to be the case with the larva of Centrotus 

 nectaris of Cevlon. Size 5x3 millimetres.
