RKVISION OF AUSTRALIAN TORTHICINA, 



base above (in L. mediana cf the posterior tibiae and basal 

 joint of tarsi are clothed with long dense rough dark grey 

 scales), forewings without the small dark brown spot on base 

 of dorsum, anterior margin of brown terminal band much 

 more convex (in L. mediana nearly straight), and more 

 acutely indented beneath costa. 



Q. : Cairns (Dodd) ; in October and November. The true 

 L. mediana occurs from Borneo to the Solomon Is., but has 

 not been found in Australia. 



422. Laspeyresia exemplaris, n.sp. 



cf 9 • 12-14 mm. Head yellow, sidetufts of crown suffused 

 with reddish-brown. Palpi yellow, base brownish-tinged. 

 Thorax reddish-brown, shoulders yellow. Abdomen dark 

 fuscous, apex ochreous- whitish. Posterior tibiae ochreous- 

 whitish, without tufts. Forewings moderate, posteriorly 

 dilated, costa gently arched, apex obtuse, termen rounded, 

 somewhat oblique ; bright yellow ; costa strigulated with dark 

 fuscous ; a very narrow brown basal fascia ; a broad light 

 brownish patch occupying terminal 'j of wing, but not quite 

 reaching costa, partially suffused with red-brownish and 

 irregularly strigulated with dark fuscous, anterior and pos- 

 terior margins suffused with violet-metallic iridescence, 

 anterior edged by a blackish line ; an oblique blue-leaden- 

 metallic striga traversing this patch near costa ; cilia brown- 

 ish, sometimes dark fuscous at apex and with two more or less 

 marked white basal dots beneath apex. Ilindwings with 6 

 and 7 approximated towards base ; blackish-fuscous ; cilia fus- 

 cous, with dark fuscous subbasal shade. 



N.A. : Port Darwin (Dodd) ; four specimens. Extremely 

 similar to L. mediana and L. hemicosma, but immediately 

 distinguished from both by colour of thorax, which in those 

 species is yellow with shoulders and anterior half of dorsum 

 dark fuscous, as well as by absence of tibial tufts and other 

 details.
