Dirce L. B. Prout (Figs 16–35)

The five species of this genus also inhabit the alpine and sub­alpine regions of Tasmania. The eggs of all three species described here are very similar. They are moderately broad, bluntly ovoid eggs with generally barely discernible cell form. However the micropylar cells are well marked with narrow and shallowly reticulated cell walls. The aeropyles are very small and inconspicuous with extremely small openings (e.g. D. lunaris Meyrick Fig. 21). The chorion of the eggs of D. lunaris and D. oriplancta Turner is smooth and undulating (Figs 20, 21& 27) but rough, wrinkled and cobbled in the undescribed Dirce sp. , similar to that of Acalyphes sp. (Figs 34 & 35).
