Nine males and one female were taken in a dry paddock on the edge of a swampy rivulet containing a few clumps of Carex, wbich has been noted as the food-plant in Viotoria. Obviously ssp. larana is extremely local since it has remained undis covered till now, although occurring in a paddock in a long settled grazing district. No other speci mens were seen outside the one narrow area in a single field clos.e to the shore-line, though I should expect it to occur in similar spots bordering running water between Marrawah and Cape Grim. South of Marrawah the country quickly changes to heathland extending to the mouth of the Arthur River, so that its possible habitable area is extremely limited.
