16 ANNALS OF THE QUEENSLAND MUSEUM, No. 2. 
centre of the corium of the fore-wings, extending from side to side and 
their membranes; portions of thepro-meso- and meta-stethiuin ; a spot 
on the 3rd, 4th, and 5th ventral segments, internal to the spiracles, 
steel-blue, with purple reflections. Eyes, antennae, rostrum, and legs 
piceous. A band on each side of the head beneath internal to the eyes 
luteous. Eyes prominent ; head wide, with the central lobe narrow and 
excavated, and the lateral ones with oblique transverse striae; ocelli 
red ; antennae rather slender, 2nd joint slightly longer than the 3rd, 
and 4th longer than either, basal joint extending a little beyond head ; 
antennary tubercles unarmed ; rostrum not quite extending to the 
hind-border of the meta-thorax ; 2nd and 3rd joints subequal; bucculi 
very low, not hiding the 1st joint of the rostrum except at its extreme 
base. Pronotum with a small tooth at each anterior lateral angle, the 
fore-border and the lateral borders narrowly reflected. Scutellum 
triangular, narrowed before the extremity and extending just beyond 
the internal angle of the corium. Corium of fore- wings with the hind- 
border scarcely sinuate, apical angle acute. Connectivum extending 
beyond fore-wings — the latter also exceeding the body. A dull finely 
wrinkled space in front and behind each excretory orifice on thorax 
beneath. Eemora unarmed. Tibiae long and channelled throughout 
their entire length externally. Length, 9 lines ; breadth, 6 lines. 
Loc. : Fly River (W. W. Froggatt). 
Var. a. Whole under surface of thorax red. 
Var. Pronotum, except at posterior lateral angles, wholly 
steel-blue. 
Suh-fam. Pentatomidce. 
16. Pentatoma $ub-marginalis, sp. nov. Above light brown, bright, 
thickly punctured, punctures piceous, eyes red ; beneath aeneous, 
brown, shining, a broad brownish white band bordering the ventral 
segments, the acetabular swellings also light-coloured. Head with 
the lateral lobes anteriorly rounded, slightly exceeding central lobe so 
as to cause a shallow emargination. Kostrum extending to the hind 
border of the second ventral segment, tip black. Antennae puberulent, 
first joint not quite reaching the fore-border of head, second, third, 
and fourth joints subequal — the second, however, being slightly less 
than the third. The anterior lateral angles of the prothorax each with 
a blunt tooth. The callous spots at the basal angles of the scutellum 
piceous. Legs pubescent, w r ith brown spots especially numerous on 
the femora ; tibiae channelled on their outer surfaces. Fore- wings 
with the membrane suffused with light-brown, its veins pale-brown 
also. Length, Q\ lines. Loc. : St. Joseph E-iver (W\ W. Froggatt) ; 
Laloki River; Fairfax Harbour. 
Note. — This insect, which also occurs at Cairns, N.'E. Queensland, is probably 
referable to the genus Oncocoris, Mayr, (vid., Voy. Novara. Hemiptera) ; it also 
seems allied to Pentatoma marginalis, Walker (Cat. Hem. Heterop. ii., p. 306). It 
is, however, larger than the latter, the abdomen is not bordered by testaceous 
nor are the legs testaceous. Moreover, the transverse ridge connecting the posterior 
lateral angles of the thorax is pronounced, and there are indications of a light- 
coloured line along it.
