slightly sinuate; corium somewhat thickly punctate, its 
margins levigate ; abdomen above obscure whitish, the disk

spot at the bases of the fourth and fifth abdominal segments. 
Loug. 44 millim. 
Hab. N.W. Australia, Baudin Island (J. 7. Walker, Brit. 
Mus.). 
The markings and punctuation of the pronotum will be 
alone sufficient to separate this species from the description 
of the only other described Australian species, G. victoria, 
Bergr. 
('OLOBATHRISTINE. 
Genus Matcuvs. 
Malcus scutellata, sp. n. 
Ochraceous, coarsely brownly punctate, the corium paler 
and almost impunctate on basal disk and lateral margin ; 
scutellum brownish, with a prominent, pale, ochraceous, levi- 
gate spot near each basal angle; membrane greyish, clouded 
with fuscous, and with the veins fuscous; legs and antenne 
very pale ochraceous, the last with the basal joint castaneous 
and the apical jomt fuscous. 
Long. 3 millim. 
Hab. Ceylon (G. Lewis). 
A species to be differentiated from M. flavidipes, Stal, by 
the prominent ochraceous angular spots to the scutellum ; 
the pronotum is also more tumid posteriorly. 
HETEROGASTRINZ. 
Genus Hyeinus. 
Hyginus signifer. 
Heterogaster signifer, Walk. Cat. Het. v. p. 74. n. 12 (1872). 
Hyginus divisus. 
Rhyparochromus divisus, Walk. Cat. Het. v. p. 105. n. 174 (1872). 
Both the above species are very closely allied. They seem 
to appertain to Stal’s genus by the long and slender antenne, 
and the convexly sinuate base of the pronotum, characters 
which separate Hyginus from Heterogaster. 
Genus nov. ? 
Heterogaster cymoides, Walk. Cat. Het. v. p. 74. n. 13 (1872), 
This species cannot be included in the genus Heterogaster,
