BuccuLATRix ciDARELLA, Zcllcr, Hcydcn (E. Z. 1862, 

 p. 365). The larva is found Sparingly around Frankfort at 

 the beginning of October, on the outside of alder leaves, on 

 the underside of which it gnaws isolated blotches. 



It changes to the pupa state in a caraway-seed shaped 

 white cocoon, with three raised longitudinal lines, and the 

 imago is developed in the middle of June of the year fol-

 the cocoon. (1846.)

 cilia are grey. Thorax, abdomen and legs shining grey.
