ORTALID^E — IDANA. 117 



equal breadth ; stigma rather long but not broad ; the crossveins 

 far distant from each other; the posterior crossvein rather oblique, 

 its anterior end nearer the apex of the wing than the posterior 

 end ; fourth longitudinal vein strongly bent forward towards the 

 end ; the first posterior cell considerably narrowed in consequence 

 towards the apex ; posterior angle of the anal cell pointed, but 

 not drawn out in the shape of a lobe. The picture of the wings 

 consists, as to color, of brownish-black and brownish-yellow and 

 some hyaline cells of a peculiar shape. The root of the wings is 

 yellow, as far as the origin of the third longitudinal vein ; the 

 extreme basis, however, is strongly infnscated ; there is a rather 

 dark-brown crossband in the region of the humeral crossvein, and 

 the basis of the marginal cell is hyaline. A dark-brown color 

 follows next, the first portion of which forms a curved crossband, 

 reaching backwards as far as the posterior basal crossvein ; ante- 

 riorly it is prolonged in the marginal cell, as far as the end of the 

 first longitudinal vein, where it stops short abruptly. After some 

 interruption,, the brownish-black color forms a broad border of the 

 anterior margin, beginning somewhat above the posterior cross- 

 vein, which does not only occupy the whole breadth of the margi- 

 nal cell, but also encroaches on the submarginal cell, follows the 

 apex of the wing and the fourth longitudinal vein as far as the 

 small crossvein and also covers the latter; posteriorly, it not only 

 runs along the posterior crossvein and extends over the end of 

 the discal cell, but follows also some distance along the end of the 

 fifth longitudinal vein, upon its posterior side ; the third longitu- 

 dinal vein is bordered with brownish-black upon its whole length. 

 The portions of the marginal, submarginal and discal cells, free 

 from the brownish-black color, are tinged with brownish-yellow; 

 the first basal cell, as well as the first two posterior cells, are 

 hyaline. The alula, as well as the anal angle of the wing and the 

 adjoining portion of the third posterior cell, is grayish-hyaline, 

 with a tinge of yellow ; the posterior side of the fifth longitudinal 

 vein has a brownish-yellow border, the middle of the third poste- 

 rior cell is rather pure hyaline, only more grayish towards the 

 posterior margin of the wing.
