somites dark-gray; terminal (anal) tiit't long, dark-gray, lighter below. 

 Thorax on the underside and femora- thickly clothed with long dirty- 

 white hairs and scales. [Pore tibiae broken ol'l'l. Middle and hind tibiae 

 and tarsi gray, spotted and I'inged with black. First pair of spurs of 

 hind tibiae very long and acute. 



Forewings on the iipperside pale gray (resembling somewhat the 

 colour of fresh s])ecimens of Catocala conciwihens Walker), greatly 

 suffused on costa and at base of wings with white scales; darker in 

 terminal area. Transverse lines visible, but very indistinct. Subbasal 

 half-line fine, angulated; basal dash absent. Antemedial (transverse 

 anterior) line forms a brown spot on the whitish costa and two denta- 

 tions below it; the rest indistinct. Median space with " dark spot in the 

 middle of costa, running into the reniform. Postmedial line (transverse 

 posterior) visible in its upper part alone, beginning with a dark si)ot 

 on the white costa and forming two subequal dentations (teeth), filled 

 inwardly with black; the rest indistinct. Subreniform absent. Reniform 

 dark-gray, edged with pure-white. Subterminal waved line distinct, 

 whitish, separated from the postmedial one by a light-brownish irregular 

 shade. Marginal lunules very small, almost wanting. Cilia uniformly gray. 



Hindwings on the upperside black, base covered by brownish-gray 

 hairs. Cilia at apex (between veins 6—8) dirty-whitish, the rest dark gray. 



Cround colour of v\'ings on the underside black: fasciae very

Forewings: base dark grayish-black, basal fascia absent; postme- 

 dial and subapical ones visible, more or less regularly excurved; between

 tremities of veins. 



Hindwings dark grayish-black, a little lighter at base and costa; 

 nu'dian fascia hardly visible, highly excurved at vein B, thus forming a 

 right angle. (Jilia light gray, with darkei- median stripe, at apex (bet- 

 ween veins 6-8) whitish. 



Catocala orha belongs to the „l)lackwing(4l" group of the genus, 

 and resembles C. judifJi Strecker (levetiei Grote) and its variety 

 miraiida И y. E d w.. but is not intimately allied to theni, I believe.
