236 DESCRIPTIONS OF AUSTRALIAN MICRO -LEPIDOPTERA. 



I have followed Zeller in reuniting to Apliomia his genus 

 Melissoblaptes, originally separated from the typical Apliomia by 

 the shorter discoidal cell of male, and not toothed basal joint of 

 antennae. The discovery of intermediate exotic species has 

 rendered this distinction untenable, although the extreme forms 

 are very diverse in appearance. A. latro, Z. } described below, 

 was referred by him to MelissoHaptes ; the other species are truly 

 Apliomia. 



The genus contains few species, but occurs also throughout 

 Europe, North America, and in Japan.

 internally edged with blackish, from § of costa to four-fifths of 

 inner margin, dentate or lunate, between £ and f of its length

 lines are two black dots, generally strong, longitudinally placed, 

 and a third less distinct immediately above them between the two;
