Genus ALBUNA Hy. Edwards 



Albuna Hy. Edwards, Papilio, vol. 1, p. 186, 1881. (Genotype, Aegeria hylotomi- 



formis Walker = Albuna pyramidalis (Walker).) 

 Harmonia Hy. Edwards, Papilio, vol. 2, p. 54, 1882. (Genotype, Harmonia morrisoni 



Hy. Edwards ^= Albuna fraxini (Hy. Edwards).) 

 Parharmonia Beutenmuller (new name for Harmonia Hy. Edwards, preoccupied), 



Bull. Amer. Mus. Nat. Hist., vol. 6, p. 89, 1894. 



This genus has been maintained distinct from Paranthrene on the basis 

 of the close proximity of veins 3 and 4 of the hindwing, which are nearly 

 connate, and on the less conspicuous transverse wrinkHng of the bursa 

 without pronounced thickenings forming the signa of the bursa. Tongue 

 well developed. Biologically also the species involved appear to be distinct 

 from Paranthrene.
