contained about* five and a half times in the length of the same; 

 costal margin straight for the greater portion of its length, arcuate 

 proximad and distad, apex narrowly rounded; costal field very 

 narrow, from about the proximal fourth gradually narrowing dLstad; 

 anal field elongate pyriform, the anal vein reaching the sutural margin 

 not quite a third the distance from the base. Wings ample, the 

 greatest width contained slightly more than twice in the length of the 

 same; apex rotundato-acuteangulate, separated from the peripheral 

 margin by a distinct obtuse-angulate emargination; anterior field 

 narrow. Supra-anal plate broadly trigonal, of similar form to that 

 of the female; subgenital plate broad, the distal extremity of the 

 margin with a slight obtuse-angulate emargination. Limbs similar 

 to those of the female, but slenderer. 



General color prout's brown, becoming isabelline on the cephalic 

 limbs and greenish on the caudal ones. Tegmina strongly washed 

 with liver brown, costal field with the veins buffy aside from the 

 subcoriaceous portion adjacent to the humeral trunk, which is of the 

 general tegminal color. Wings infuscate with bistre, the cross veins 

 white, greater portion of the costal margin and a small area at the 

 base of the wing claret brown.

In addition to the type and allotype, we have before us two male 

 and three female paratypes. The specimen referred to by us (vide 

 supra) from Rio Grande do Sul, Brazil, received from Saussure and 

 determined by him as gayi, is clearly referable to this species. In 

 size the Sapucay specimens show but little variation for this genus, 

 while the color varies appreciably in intensity in the females and in 

 the males to the extent noted in the paper quoted above.
