 pale ocher yellow, the costa white; basal space pale gray, cut into 

 bars by the whitish veins, narrow on costa, a crimson mark on inner 

 margin at base; an upright pale gray hand across end of cell, expanded 

 on costa and below vein 2, cut into bars by white veins and edged on 

 both sides by white below vein 2; a crimson mark on vein 1 at anal 

 angle; a round gray spot between veins 5 and 6 outwardly. Hind

Type.— Cat. No. 12949, U.S.N.M. 



Allied to Idalus admirabilis Cramer and /. agastus Dyar ( = piches- 

 ensis 1 Iampson, not Dyar). It differs from the former in the presence 

 of a crimson mark on vein 1 outwardly and from the latter in the 

 shortness of this mark and in the shape of the gray hand. In agastus 

 this band is strongly cut by the pale veins and is produced outward 

 below nearly to the anal angle, while in agricus it is only faintly cut 

 by the veins and is but slightly produced, terminating roundedly 

 between the vein^.
