LÉPIDOPTÉROLOGIE COMPARÉE 385 



The ground colour of the wings is whitish ochreous, very 

 strongly mixed with black scales, so much so, that the wings may 

 be wholly black. In some, the ground is yellower than in others. 

 The markings, such as they are, follow hirtaria but in very many 

 cases they are total ly overwhelmed by the black scales. Gene- 

 rally, as in hirtmia Q, the terminal suffusion is obsolète, and the 

 wings then terminate with a pale band. The praîsubterminal 

 suffusion is indicated and follows the same path as in the cf, 

 but is slightîy straighter. Before it, is barely visible the pale 

 ground and then, in some, a trace of the 2nd line. The space 

 along the inner margin before vein i, is distinctly paler, The 

 hindwings are nearly the same as the forewings, but are, for the 

 most part, paler. 



Like hirtaria Q, the scaling of the wings is rather weak, but 

 the scales themselves are strong and hairlike, the tendency to 

 develop into hairs bemg very great along the costa and toward 

 the base of the wings, although the hairs are never so long nor 

 so pale as in zonaria. The pale fringes too, are coarse and hair- 

 like and blackish mixed. The veins are outlined in black and, 

 except that they are nearer together, they resemble in position 

 those of hirtaria Q. The antennae, which are short and thick, 

 are very like those of zonaria, for they are covered with white 

 scales. 



The thorax approaches that of hirtaria in shape as it is longer 

 than in zonaria. It is rough-haired and, hirtaria like is grey and 

 black, the patagia being rudely outlined in grey. There is no 

 trace of the long pale hairs of zonaria. 



The collar in zonaria is strongly marked and is pale in colour. 

 It is similar but weaker in harrisoni and almost undifferentiated 

 in hirtaria. The abdomen of harrisoni is stout; it is longer than 

 that of zonaria and like it, is black, yellow ringed. The fur, 

 however, is not so thick and long and resembles hirtaria fur in 

 appearance, but not in colour. 



Ventrally, the face, thorax, abdomen and femora of zonaria 

 are cl ad with a thick covering of short pale hairs. Harrisoni
