Imma grammozona, n. sp. 
cT 5 . 27-34 mm. Head, palpi, thorax orange to yellow- 
whitish, palpi more or less blackish-sprinklecl anterior^ towards 
apex, thorax with 4 black stripes. Antennae <3 very shortly 
ciliated. Forewings rather broad, dilated, termen rounded, hardly 
oblique ; 7 and 8 stalked, 8 to apex ; orange to orange-whitish, 
markings black ; a line round costa and termen, on termen including 
a leaden marginal line ; a streak from base of dorsum just above 
dorsum to tornus; interneural streaks from base above 1 b and 
beneath cell to about middle of wing, one above 12 seldom reaching 
costa, one above cell and 11 seldom reaching costa, and a streak 
within cell disconnected or rising out of preceding, not reaching 
a mark on upper part of transverse vein ; a fasciate band of 
interneural streaks between veins 2-11 diminishing downwards to 
tornus and terminated by a short mark beneath 2, not reaching 
margin but leaving a narrow fascia of groundcolour widest opposite 
apex: cilia dark grey, basal third black. Hindwings blackish ; 
an orange marginal fascia round apex and upper part of termen to 
near middle, variable in width but widest above and narrowed to a 
point beneath, enclosing a short black streak on apical edge, some¬ 
times very small; cilia dark fuscous, round upper part of termen 
orange. 
British Hew Guinea, Milne Bay; Biagi, Mambare E. ; Ow- 
garra ( Meek ); 8 ex. These vary to some extent locally, the 
specimens from first locality being larger and orange, those from 
the last smaller and orange-whitish, the Biagi specimen inter¬ 
mediate, but there is no definite distinction. 
Imma tonans, n. sp. 
S 2 • 32-36 mm. Head, palpi, thorax light ochreous-yellow, 
collar mixed dark fuscous, palpi sprinkled dark fuscous anteriorly 
towards tip, thorax with 4 blackish stripes. Antennae <3 moderately 
ciliated. Forewings moderately broad, dilated, costa moderately 
arched, termen rounded, little oblique; 7 and 8 stalked, 8 to apex ; 
ochreous-yellow, markings purple-black ; a costal streak to apical 
patch, and dorsal streak to about f ; a basal mark from which rise 
streaks above and below cell diverging from a point and not reaching 
middle, and a streak below fold parallel to lower of these; a large 
apical patch, edge rather concave and running from middle of 
costa to tornus, enclosing a subcrescentie transverse ochreous- 
yellow streak before apex: cilia dark grey, basal half black. 
Hindwings black; a curved ochreous-yellow fascia from costa 
posteriorly to near middle of termen, widest on costa, and narrowed 
to a point beneath, leaving a black marginal streak round apex and 
termen ; cilia as in forewings.

Bay; Biagi, Mambare E., 5000 feet; Goodenough I., 2500- 
4000 feet; February, March (Eichhorn , Meek ); 5 ex. Very close to 
minatrioo , but distinguished by wholly dark cilia of hindwings (in
