326 MR. W. Li, DISTANT ON THE RHYNCHOTA [ Apr. 16, 
constitute the material described in the second part of that 
Catalogue ; the revision of the Pentatomide treated in the first 
part, the Society has already done me the honour to publish in 
their ‘ Proceedings ’ (1900, p. 807). The introductory remarks there 
given are also applicable to this concluding instalment and need 
not be repeated. 
Owing to the very attenuated descriptions given in _ these 
catalogues, considerable synonymy has been created by other 
workers, which under the circumstances may cause regret but no 
surprise. 
Subfam. Micrinz. 
MELANTA, gen. nov. 
@. Body oblong, compressed. Head subqnadrate, distinctly 
excavated between the apices of the lateral lobes ; antenne simple, 
third joint not dilated, first and fourth joints subequal in length ; 
rostrum passing the anterior coxe, third joint shortest ; pronotum 
about as long as broad at base, lateral margins not denticulated, 
lateral angles not produced. Abdomen distinctly broader than 
corium, its lateral margins dentate, apical angles of second, third, 
fourth, fifth, and sixth abdominal segments distinctly spinous ; 
abdomen beneath at junction of second and third abdominal 
segments armed with two long diverging spines. Posterior femora 
wide apart, regularly incrassated, about “equally thick throughout, 
armed above and on sides with four series of spinous tubercles, 
and with a short but robust spine near apex beneath; posterior 
tibie dilated on each side, convexly outwardly, and angulately and 
truncately narrowed on inner margin at about one fourth from 
apex. 
This genus is allied to Pternistria, Cipia, and Odontoloba, from 
all of Hnee. apart from other characters, if may be separated by 
the dentate lateral margins of the abdomen and the spinous apical 
angles of the abdominal segments. The tuberculated posterior 
femora reflect a character in Prionolomia. In the female the 
posterior tibie are simple, the posterior femora less tuberculate 
than in the male, the abdomen unarmed, and the abdominal 
margins much less denticulate and spinous than in the other sex. 
MELANIA GRACILIS. (Plate XXIX. fig. 4, 2.) 
Q. Myctis gracilis Westw. in Hope Cat. ii. p. 11 (1842). 
6. Dark castaneous, finely ochraceously pilose; connexivum 
piceous; eyes, abdominal spines, apex of scutellum, and sub- 
quadrate spots to connexivum pale ochraceous ; antenns, anterior 
and intermediate legs, and the posterior tarsi ochraceous. Abdomen 
above black, with two discal longitudinal series of ochraceous 
spots. 
The-antenne have the first and fourth jeints subequal in length, 
the second a little longer than the third, the first and fourth 
longest ; the pronotum is granulate and coarsely punctate; the 
scutellum is irregularly transversely rugose, its apex levigate ; the
