MEMBRA CIDJE. 
posterior horn is shorter and the abdominal rings are edged with fuscous 
yellow. 
Though Fairmaire notes that the scutellum is white at the base, I am inclined to 
think this is a slight sexual character, or possibly only climatic. 
Size, 8x5 mm.

LEPTOCENTRUS ADUNCUS, n.s. 
(Plate LIII. fig. G.) 
Dark fuscous, shining and punctured. Suprahumerals short and auriculate. 
Posterior horn stout at the base and short. Tegmina fuscous. Frons hairy. 
Size, 8x5 mm.

LEPTOCENTRUS USTUS, I, n.s. 
(Plate LIII. fig. 7.) 
Small, nearly black in colour. Posterior horn very slender and thin at the base. 
Tegmina lustrous, with fine brown neuration. Abdomen stout, and nearly as long as 
the tegmina. Tibiae slightly flattened. 
Size, 5x3 mm. 
Habitat. —Ceylon, Madras. 
LEPTOCENTRUS CINCTUS, n.s. 
(Plate LIII. figs. 8, 8a, 8b.) 
Small and slender, with rather erect and sharp suprahumerals. Posterior horn 
rising erect from the dorsum, and then reflected as a thin and free process to the tip 
of the tegmina. Colour brown, with a broad and white tomentose band at the margin 
of the pronotum, which band is continued below the abdomen, and covers the coxae. 
Tegmina rather slender, with broad yellow neuration, narrow apicals, and with no 
limbal border. 
I could only count two discoidal areas, but an exact mapping out of venation in 
many species of the Centrotidse is hardly attainable. 
Size, 7x3 mm. 
Habitat —Calcutta.
