Beadily distinguishable from the other Australian species by 

 the brown clouding of the apex of the wings ; in the anterior 

 wings this clouding is confined to the poststigmatical costal 

 space, but in the posterior it invades almost the entire apex. 

 The anterior wings are comparatively shorter and broader than 

 in the allied species. I have an individual from the same lo- 

 cality as Brauer' s. 



6. S. inconspicua, nov. sp. (Antennae mutilatae.) Frons niger, 

 griseo-villosus. Clypeus labrumque flavi. Vertex niger, nigro-vil- 

 losus. Occiput nigrum, in medio flavum. Thorax fuscescens, griseo- 

 villosus, supra et infra indistincte piceo-notatus. Pedes nigri, ni- 

 tentes; femoribus (ad apicem exceptis) rufo-flavis. Abdomen ni- 

 grum, nitidum, maculis lanceolatis dorsalibus, in medio, utrinque 

 ad basin, marginibusque posterioribus segmentorum, supra, infra et 

 utrinque interruptis, aurantiacis. Alae elongatae, posticae anticis valde 

 angustiores ; humeris flavis ; pterostigmate parvo, intense nigro. 

 Long. corp. 12"'; exp. alar, antic. 26"', postic. 24"'.

7. S. sabulosa, Walker. (Ascal. sabulosus, Walk. Cat. Brit. Mus. 

 Neurop. p. 42/.) Antennae nigrae, ad basin flavae; clava flava, infra
