404 LÉPIDOPTÉROLOGIE COMPARÉE 



near the base and on the costa, as well as on the fringes. The 

 fringes on the smaller examples, are much more Hke hairs than 

 on larger ones. 



The veins, especially near the cell, are black marked. Ail the 

 lines seen in hirtaria cross the wings, but, except the second on 

 account of the rough scaling, are much suffused. The ist and 

 médian, although slightly more oblique, are like those in hirtaria; 

 the second is quite straight and is parallel to the termen. The pale 

 subterminal band is présent but, owing to the weakness of the 

 terminal suffusion in the hirtaria g it is terminal hère. 



The hind wings are paler, freckled with black. There are but 

 f aint traces of the médian line although the second is well marked. 

 The antennse are much stouter than in ponionaria. The thorax also, 

 is hirtaria like, but is paler. The fur is fî.ner and there is the same 

 black outlining of the pale collar and patagia developed. The 

 metathorax is blackish. 



The abdomen is long and narrow and is black, covered with 

 almost the same, but paler, mouse grey hair, as in the maie. Below, 

 the whole of the body is covered with fur of like character to that 

 in hirtaria although the colour is duller.

Variations of imagines. 



As in harrisoni and denhami, the variation is toward the pro- 

 duction of spécimens more or less suffused with black in the maies, 

 and, as in those hybrids, the suffusion may totally obliterate ail 

 the lines and markings except the pale subterminal band. The 

 other points of variation are but slight, the only one worthy of 

 note being the tendency of the suljtermmal band to be broader and 

 less toothed than usual and thus to approach hirtaria. 



The chief variation in the female is in the shape of the wings 

 and this has been considered above. Otherwise the trend is toward 

 the disappearance of the lines and toward the same blackish suffu- 

 sions as in the maie, although the suffusion is, in some cases, most 

 curiously limited to the extrême tip of the wings.
