Chrysolarentia Butler (Figs 725–761)

Chrysolarentia is widespread in Australia. This large genus is represented by approximately seventy species of colourful, diurnal moths in Australia. Eight species are described. The eggs of these species are all almost totally unmarked apart from the micropylar cells and have a soft chorion. C. decisaria Walker and C. heliacaria Guenée are distinguished from their congeners by their unusual pyramidal shape. This shape is also found in the Nearctic larentiine Dysstroma hersiliata, Guenée (Hydriomenini) ( Salkeld 1983); the eggs of this species also generally resemble those described in this group. The eggs of C. euclidiata Guenée are very different from that of its congeners in shape and general morphology. These eggs are rather cylindrical, the cell form is wellmarked on all surfaces and the chorion rough and cobbled. This egg is similar to that of the xanthorhoines A. orina (see above) and Epyaxa subidaria Guenée (described below) and the hydriomenines nr. Aponotoreas (see above) and the Nearctic Anticlea multiferata Walker (in Salkeld 1983). The shapes of the eggs of the other species vary from narrow and elongated to broad and bluntly ovoid. Aeropyles are usually inconspicuous or not visible, unelevated and with small openings and are not present on the top, wide lateral side. The chorion is smooth with shallow undulations. The eggs of the Australian xanthorhoine Chrysolarentia vicissata Guenée ( McFarland 1988) resemble the eggs of Chrysolarentia in general shape.
