Casbia Walker View in CoL (Figs 555–575)

This large genus is represented by thirty species that mainly occur in southern Australia. Most species feed on Rhamnaceae . The eggs of the three species described here are very similar and those of C. melanops and C. crataea are almost indistinguishable. All are narrow, elongated and bluntly ovoid eggs with a soft chorion. The eggs are marked conspicuously on all surfaces with flat, elongated and quadrate cells with narrow, elevated walls arranged in longitudinal rows on the wide lateral sides. In C. farinalis the longitudinal and anterior pole cell walls are markedly elevated and frilled. The aeropyles in C. melanops and C. crataea are elevated and conspicuous with moderately large openings whereas those in C. farinalis are inconspicuous with small openings. Aeropyles are absent from the middle area of the top of the wider side. The chorion is either shallowly wrinkled or ridged. The eggs of C. farinalis greatly resemble those of Taxeotis sp. ( Oenochrominae s. l.) described below.
