LEPISESIA FLAVOFASCIATA Walker. 



Six specimens, June (>, 7, !*, at flowers of lilac. Mr. Cockle has 

 several others. The specimens vary in the width of the orange hand 

 on the hind wing-s from a l)road band to near obsolescence. The collar 

 may be deep black or only slightly blackish, as indicated by the 

 varietal names ulaluniie Strecker and racliel Bruce. Mr. Bruce has 

 noted the larva on Ep'dolj'nun." Eggs were obtained from captive 

 females and the little larvae selected this plant from a variety of plants 

 offered them. Until the last stage the larva is green with a red anal 

 horn; in the last stage nearly coal ))lack with a shining button. The 

 change is remarkable and interesting.
