CONTRIBUTION TO THE LIFE-HISTORY OF LIPHYRA 

 B1USS0LI8, Westw. 



By F. p. Dodd. 



(Concluded from p. 156.) 



The perfect insect comes forth in twenty-one to twenty-five 

 days, and further astonishing developments in the life-history of 

 this strange insect occur. Before bursting the outer shell the 

 butterfly can be heard moving within, and shortly a sharp 

 cracking sound announces that the burst has been effected, then 

 either a [)ortion of the shell, which opens in the centre in front 

 up to the first furrow, is broken right out, or it opens sufficiently 

 above after breaking away at the rim to admit of the imago's 

 emergence. But who would recognize L. brassoUs now as he 

 crawls out ? Instead of the weak drooping wings of a butterfly, 

 he has little short appendages like a freshly-emerged moth, arid 

 lying very flat ; the front wing is creamy white to extreme tip, 

 and the edge of the hind wing projects from under this ever so 

 little ; the abdomen looks very large, a thick mass of furry- 

 looking substance showing on each side of it to the tip ; on the 

 thorax small tufts of loose brownish scales may be noted, which 

 easily roll off. It is soon seen that the white appearance of fore 

 wing is caused by a dense covering of fugitive scales ; there is 

 also a small patch on each side of thorax. As the wings slowly 

 lengthen, the density of the scales lessens sufliciently to admit 

 of a view of the black and rich yellow colouring underneath.
