This species belongs to the type of A. pellucida. The wings 
are pellucid, costal margin yellow, apex and anal area (partly) 
blackish. The specific name refers to the characteristic marking 
of the elytra.

The genus has not been recorded hitherto from Australia 
(except by Walker, whose determinations are too indefinite for 
identification in most cases), but being widely distributed (India, 
America) its occurrence is not unexpected. The described speci- 
men differs, however, from the typical species in having the 
middle vein scarcely angulated. The left elytron crosses the right 
at rest and covers the latter completely at the apex, the line of 
demarcations being deeply impressed and extending obliquely 
from near the base of the lower elytron to near the apex, indent- 
ing all the veins. This appears to me to be rather uncommon. 
The wings also seem to exhibit some differences ; the border is
