142 HAUSTELLATA. LKPIDOPTERA.

There is so much apparent difference in the sexes of this pretty 

 species at a glance, that they not only seem to belong to different 

 insects, but they have been described as such : a slight exa- 

 mination, however, readily shows their disparity to be merely that 

 of sex; a fact that has been incontrovertibly proved by various 

 persons. Until within these ten years, it was esteemed a scarce 

 species ; but it has lately occurred rather plentifully in several 

 places : I have taken it often at Coombe and Darenth Woods, at 

 the end of May and beginning of June. " Near Cheltenham, 

 Gloucestershire."''' — Dr. Leach. . " In Clapham Park Wood, Bed- 

 fordshire."" — J. C. Dale, Esq.
