Of this wide-spread Australian species, I have seen one speci- 

 men fn^ni Queensland, in Coll. Froggatt; and several specimens 

 from Oahu. I have seen also a very fine undescribed species 

 from Australia. 



FOKMICALEON. 



Banks, Ann. Ent. Soc. Amer., p. 16(1 911). 



The genotype is F. tetragrammicus Fabr., in which the bent 

 branches of the radial sector form a straight line through the 

 middle of the apical part of the wing. 



I call attention to the fact, that this line is wanting in some 

 of the Australian species hitherto placed in this genus. These 

 species may be placed in a new genus, and I propose the name 

 Allqformicaleon, with F. mistralis Esb.-Pet., as genotype; but I 

 will postpone giving a more complete description of the genus 

 until more material is at hand.
