Genus Empuusis. 
Emphusis, Buckt. Monogr. Membrac. p. 256 (1903) ; Dist. Faun. Brit. 
Ind., Rhynch. iy. p. 36 (1907). 
Emphusis occidentalis. 
Centrotypus occidentalis, Goding, Proc. Linn. Soc. N.S.W. xxviii. 
p- 27 (1903). 
Hab. West Australia ; Swan River (Brit. Mus.). 
Sertorius affinis, sp. n. 
Head and pronotum piceous ; legs castaneous, apical areas 
of the tibize ochraceous ; lateral areas of sternum and a spot 
at each basa] angle of scutellum ochraceously tomentose ; 
membrane subhyaline, wrinkled, veins ochraceous, those to 
costal and subcostal areas castaneous, base piceous ; pro- 
notum thickly punctate, the lateral processes slender, acute, 
strongly outwardly directed, their apical areas black, cen- 
trally carinate, the posterior process tricarinate, robust and 
convex above scutellum, and then straightly directed and 
attenuate to apex, which just passes the posterior angle of 
inner tegminal margin. 
Long., incl. tegm., 8 mm.; exp. lat. pronot. process. 4mm. 
Hab. New South Wales ; Sydney (J. J. Walker). 
Alhed to S. australis, Fairm., from which it differs in the 
more slender, straighter, and acute pronotal lateral processes 
and the basally convex and apically straight posterior process. 
Sertorius castaneus, sp. 0. 
Head and pronotum castaneous ; body beneath more or 
less ochraceously pilose ; legs pale castaneous ; lateral areas 
of sternum and basal angles of scutellum palely ochraceously 
pilose ; tegmina subhyaline, wrinkled, venation ochraceous, 
base castaneous; pronotum coarsely punctate, moderately 
centrally carinate, the lateral processes apically acute, out- 
wardly, not upwardly, but distinctly a little backwardly 
directed, posterior process tricarinate, gradually narrowing 
from base, impinging on tegmina, but not reaching tegminal 
apex. 
Long., incl. tegm., 8 mm.; exp. lat. pronot. process. 44 mm. 
Hab. Australia (no precise locality). 
In colour allied to S. luteus, Buckt., but differimg in the 
more rugosely punctate pronotum and its more slender 
lateral processes ; viewed from the front these processes are 
longer and more straightly directed.
