of both wings has the spots situated similar to those in 

 polysema, but the costal, apical, and terminal areas of fore- 

 wings and nearly the whole of hindwings are suffused with 

 pale-lilac blue, whereas in polysema the ground-colour is 

 yellowish-fuscous, so that probably argina represents a species 

 allied to polysema, but separable by the above-mentioned 

 differences. The locality given is Brisbane, and the expanse 

 (one wing only) is 15 mm. Polysema has so far been recorded 

 only from Chillagoe district and Port Darwin.
