posterior angles rather variable, slightly obtuse or right, 
more or less denticulate ; base slightly sinuate ; apex slightly 
and broadly emarginate, the anterior angles scarcely ad- 
vanced beyond the line of the emargination, narrowly 
rounded; lateral margins very narrow, scarcely wider to- 
ward base; baso-lateral impressions normal, linear, im- 
punctate, reaching base; middle line distinct, transverse 
impressions sub-obsolete; disc impunctate, with lightly im- 
pressed transverse wrinkles; basal and apical marginal 
lines widely interrupted at middle. Elytra subparallel, not 
or slightly narrowed anteriorly, not much wider than pro- 
thorax (1.13 and 1.17 as wide in measured $ 9) ; basal 
margin entire; strongly (almost acutely) angulate and sub- 
dentate at humeri; striae deep, impunctate; intervals con- 
vex, not catenulate (except extreme lateral ones), 3rd 2- 
punctate, the punctures near middle of length and behind 
apical 1/4. Length 13.5-18.0; width 4. 0-5. 3 mm. 
Holotype S (M. C. Z. Type No. 29,012) and 16 paratypes 
all from Mt. Spurgeon, North Queensland, 3,500-4,000 ft. 
altitude, July, 1932, in “scrub” (rain forest). 
This new species is sufficiently compared with others in 
the key, above. 
Notonomus masculinus n. sp. 
With characters of doddi subgroup (above) ; a little 
broader than usual but otherwise of about average form for 
genus; black, faintly purplish above, greenish at middle 
of pronotum, appendages black to piceous; head and pro- 
notum dull, elytral intervals more shining ; reticulate micro- 
sculpture very fine and isodiametric on head and elytra, re- 
placed by close longitudinal strigae on pronotum. Head. 
normal, not large, .66 and .65 width prothorax in ^ $ 
measured. Prothorax 1/4 to 1/3 wider than long; base 
1/5 or less wider than apex ; sides moderately arcuate, then 
straight and converging to obtuse but denticulate posterior 
angles; base slightly sinuate; apex broadly emarginate, 
with anterior angles not advanced beyond line of emarg- 
ination, narrowly rounded; lateral margins very narrow; 
baso-lateral impressions linear; disc almost flat, impunct- 
ate, with middle line distinct but transverse impressions 
obsolete; base and apex not margined at middle. Elytra
