II.—HOPLOPHOBIN.E. 
The foregoing and fh’st section of the Membracidae, though very diverse of form, 
is characterised chiefly by the spatulate character of the anterior and intermediate 
pairs of tibiae. The second and present section shows the tibiae plain, with the 
posterior tarsi very short, much shorter than those of the anterior and intermediate 
pairs. 
The Tegmina (wings, according to Fowler) show either four or three apical cells. 
4 Apicals. — Triquetra, Fairm. Ochropelta , Stal. Potnia, Stal. Aconophoroides, Fowler. 
3 Apicals. — Plati/cotis, Stal. Orthoplophora, Fowl. Hoplophora, Germ. Umbonia, Burin. 
Though, perhaps, not so varied in their general aspect as in the last section, the 
pronota take some extreme shapes, which are not always sustained in the different 
sexes, the males being sometimes exceptionally furnished with greatly developed 
procephalic horns, as in the genus Umbonia. However, in this particular there is 
much variety, some males being, even in the same species, much smaller and more 
brightly coloured than in others. 
The group is not a very large one, but some remarkable insects are included in it. 
About seventy species have been named by Stal and other authors, and new 
genera added by them. The subjoined list has been collated with the kind assistance 
of Mr. W. F. Kirby. Some of these species are very difficult to verify without the 
aid of figures. In a general way they may be thus numerically shown:— 
HOPLOPHORIN^E. 
Umbonia , Burm., 10 species. 
Triquetra ;, Fairm., 12 species. 
Potnia, Stal., 5 species. 
Enchotype, Stal., 5 species. 
Plati/cotis, Stal., 10 species. 
Lophopella, Stal., 3 species. 
Iloplophora, Germar, 15 species. 
Microschema, Stal., 5 species. 
Orthoplophora, Fowl., 1 species. 
Aconophoroides, Fowl., 1 species. 
Ochropepla, Stal., 6 species. 
Genus: UMBONIA. Burm. Fairm. Fowler. 
Burm. Handl. Ent. IT. p. 138 (1835). 
Characters like those of Hoplophora, but modified; pronotum as long as the 
abdomen, sometimes extending to the tips of the tegmina; dorsum with a sharp and
