In forewings veins ID and 11, coincident, anastomose only at a point with 12 ; 

 the palpi are thickly scaled and large for the size of the insect ; but it agrees 

 with the type species j.V. fuscaM Warr. in the unusual anastomosis of the costal 

 and subcostal of hindwiugs.

Underside the same. Head, thorax, and abdomen black ; the abdomen with an

Numerous $ S from Cajamarca, Peru, 2800 ft., and Paramo, Peru, December 

 1899, dry interval (Simons). 



The SS flew iu the sunshine; as no ? ?were taken, it is suggested that this 

 sex may be apterous.

 slightly concave or inangulated ; first median at one-half, second close before third ; 

 radials normal ; 7, 8, 9, lO stalked from before upper angle ; 11 anastomosing with 

 12, 10 with 11 and again with 8, 9 : hind wings, cell not half as long as wing ; 

 costal shortly approximated to subcostal ; 7 well before angle of cell ; first 

 median at one-half. Forehead hardly prominent ; palpi with third joint pointed 

 and decumbent, the three transverse lioes waved and parallel to one another ;
