but the condition of Walker’s unique type is not sufficiently 
good for exact generic localizatioa. 
Dinomacuus, gen. nov. 
Allied to the Palearctic genus Heterogaster *, from which 
it differs by having the central lobe longer than, and pro- 
jecting beyond, the lateral lobes ; the head and body are also 
more elongate. 
Dinomachus Marshalli, sp. n. 
Ochraceous, thickly punctured with piceous ; eyes black ; 
corium with a spot near anterior third of lateral margin, 
another near apex of claval margin, and the apical third 
black, the last with two median spots and the apex ochra- 
ceous ; membrane brownish ochraceous ; connexivum ochra- 
ceous, spotted with black ; body beneath piceous, greyishly 
pilose ; cox, legs, disk of abdomen, and marginal spots 
ochraceous; femora punctured with brown on their basal 
areas and biannulated with the same colour near their apices, 
tibize with three brown annulations. 
Pronotum with a somewhat obscure central transverse 
impression, and a central raised longitudinal line which 
extends through the apical area of the scutellum, but is 
obsolete on its basal area; apex of scutellum pale levigate ; 
second joint of antenne considerably longer than the first, 
remainder mutilated. 
Long. 10 millim.

PACHYGRONTHINE. 
Pachyyrontha Walkeri, sp. n. 
Dark ochraceous, shaded with castaneous ; antenne, a 
central levigate line to pronotum (not reaching base), a central 
levigate line to scutellum, and a levigate spot near each lateral 
angle, lateral margins of corium, lateral margins of abdomen 
beneath, bases of femora, the tibize and tarsi pale ochra- 
ceous ; apices of first joint of antennie broadly, of second 
joint narrowly, a broad annulation before apex of third, 
posterior angles of pronotum, posterior margin (sometimes 
broken up in spots) of corium, apical joints of tarsi, and 
membrane (excluding base) piceous. 
Antenne with the apex of the basal joint prominently 
* I do not include the species described by Carpenter as H. australis 
from Murray Island.
