 tiago, Cuba, January, 1903 (W. Schaus). 



Arbostola Druce. 



Druce described Arbostola (?) viridis (Ann. Mag. Nat. 

 Hist. (7), V, 519, 1900). It is probable that the generic name 

 is a clerical error for Ahrostola Ochsenheimer ; but the pres- 

 ent species falls in a different subfamily, and the spelling is 

 sufficiently different not to cause confusion. The genus, as 

 founded on the type species, viridis Druce, falls in the Noc- 

 tuinse. On the hind wings, veins 3 and 4 are connate from a 

 point of the cell, 5 arising shortly above ; fore wing with a 

 long areole, vein 11 from the cell ; palpi sharply upturned, 

 reaching shortly above vertex, the last joint about half as long 

 as the second, pointed ; femora and tibiae clothed with long red 

 hair in both sexes ; antennae simple ; vestiture of hair and hair- 

 like scales, erect on tegulse and prothorax, forming a distinct 

 tuft on metathorax ; abdomen with rough hair at base, but not 

 tufted. 

 Arbostola heuritica, new species. 



In viridis Druce the wings of the male are normal below ; 

 in the present species they are roughened with erect scales 

 on the tips of both wings, ocherous outwardly. In the male 

 the hind wings are white above, female with dark veins and 

 fuscous shaded outwardly. Fore wing much as in viridis, 

 except that in the male the green color is confined to the area 

 along the inner margin, and in the female, it occupies the 

 whole of the terminal space also, up to the outer line.

 the same data, and a third male, Benito Province, Pernambuco,
