and a line before the concolorous cilia rather darker. On 

 the underside they are finely reticulated with darker, and 

 this shows through faintly on the upper side. 



Head with the antennae and palpi, and also the thorax, 

 dark grey; abdomen and legs rather paler. Anal tuft of 

 the male short, yellowish-grey ; in the female the last seg- 

 ment is more rounded. 



In one variety from Ragatz (var. Ragatzanay Heyd.), 

 the triangular blotch is extended and occupies the entire 

 apical portion of the wing, and is more blackish, less inter- 

 rupted with pale spots; the basal portion is whitish, with 

 larger blackish spots at the base, on the costa and below the 

 hinder margin of the triangle. 



The larva feeds on Hippophae rhamnoides, especially at 

 the ends of the branches, between leaves spun together in a 

 ball, and here also it changes to the pupa state. 



I first found the larva in the middle of August, 1851, at 

 Ragatz, and the moths made their appearance from the be- 

 ginning of September to the beginning of October. In 

 1861, I found it about the same time at Neuberg on the 

 Rhine in Baden. (1851.) 



Teras Parisiana, Guenee, Heyden (E. Z. 1863, p. 342). 

 The larva occurs near Frankfort, Darmstadt, Mayence and 

 Wiesbaden throughout September abundantly on elms, 

 between leaves spun one upon another, and there it also 

 changes to the pupa state. 



The imago appears at the end of September and beginniug 

 of October. (1834.)
