358 REVISION or Australian lepidoptera, 



mori vein 11 of hindwings is present, running into 12, and vein 1 of the fore- 

 wings is distinctly developed in its distal half. In the Indian Ocinara and the 

 Australian Gastridiota vein 1 is present in both wings. 



1. Both wings with vein 1 absent 2. 



Both wings with vein 1 present 3. Gastridiota. 



2. Both wings with 3 and 4 stalked 1. Panacela. 



Both wings with 3 and 4 separate 2. Mallodeta. 



Gen. 1. Panacela.

Palpi vei7 short and concealed by hairs. Forewings with 1 absent, 3 and 4 

 stalked, 5 from upper angle of ceU, connate or short-stalked with 6, 6, 7, 8, 9 

 stalked, 10 absent; cell short (about one-fourth). Hjndwings with 1 absent, 3 

 and 4 long-stalked, 5, 6, 7 stalked, 12 fused with upper margin of cell near base, 

 thence diverging; cell short (about one-fourth). 



Well characterised by the long-stalking of veins 3 and 4 of both wings. I 

 do not know of any extra-Australian species.

d". 28-32 mm. Head, antennae, thorax, abdomen, and legs reddish-grey. 

 Forewings triangular, costa straight to three-fourths, thence strongly arched, apex 

 pointed, produced, termen sinuate; reddish-grey; two oblique dark-reddish lines, 

 from one-third and two-thirds costa to one-third and two-thirds dorsum, some- 

 times replaced by a broad, dark-red, oblique band; a faint, crenulate, subterminal 

 line, fuscous or dark-reddish, sometimes reduced to dots on veins; cilia dark- 

 reddish, becoming reddish-grey towards tornus. Hindwings with termen obtusely 

 bent and prominent in middle; colour as forewings, but lines very indistinct or 

 obsolete; cilia reddish, on dorsum fuscous or dark-reddish with two whitish bars. 



?. 34-42 mm. Forewings with ap-ex not pointed, not produced, termen 

 scarcely sinuate; pale-fuscous, thinly scaled; lines slightly darker, suffused. Hind- 

 wings shaped as in c?; colour as forewings; lines obsolete or very obscurely in- 

 dicated; dorsal cilia with two obscure whitish bars. 



The sexes differ much, but, except for the occurrence of banded forewings 

 in the c?, there is little variation. The larvae are gregarious and inhabit bag- 

 shaped shelters on Exocarpus, Tristania and doubtless other trees.
