LEPTOCENTRUS LEUCASPIS, Walk. 
(Plate LIII. figs. 3, 3a, 3b.) 
Centrotus leitcaspis, Walk. l.c. p. 158. 
Black. Pronotum subpunctate, with long suprahumeral horns, slightly ascending 
and curved backwards. Two white tomentose spots occur on the dorsum, or else one 
large one, slightly divided. Posterior apical horn slender, rather arcuate, free from 
the dorsum and reaching almost to the tips of the tegmina. Tarsi ferruginous. 
Tegmina each with five apicals, membranes testaceous, with a dense costa. The 
white patches are most marked in the females. 
This species appear to be commonly diffused. I have examples with slight 
differences in the development of the lateral horns from Madras, Sikkim, Ceylon, 
Java, the Philippines, and Timor. The island forms have the shorter suprahumerals. 
Walker says that this species is erroneously recorded as C. taurus, in his Cat. 
Horn. p. 602. 
Some species are white on the pectus. 
Size, 8 x 4 mm. 
Habitat. —India, Java, Philippine Isles. 
LEPTOCENTRUS MEPHISTOPHELES. 
(Plate LIII. fig. 4.) 
This insect differs from L. leucaspis in wanting the white tomentose patches on 
the dorsum, and in the browner colours of the pronotum. The abdomen of the male 
is stout and ringed, and the pronotal posterior is shorter and rather more curved. 
The suprahumerals are somewhat slender, but variation is common as to their 
curvatures. The tegmina are hyaline. 
Taken by Dr. J. Pilcher in August in the Sikkim Himalayas at an elevation of 
2800 feet. 
Size, 8 x 4 mm. 
Habitat. —India. 
LEPTOCENTRUS GAZELLA.

Much like L. leucaspis without the grey patches on the pronotum, but the
