This very delicate luteous species, witli an almost imperceptilde greenish 

 tinge, is, on both wings, Hecked irregularly with darker scales, with no lines, 

 except a subniarginal, waved, tine, white line, with black points, on the 

 venules. It may also be recognized by the short hind wings, with the outer 

 edge much less convex than usual. Its range is wide, as it was one season 

 common in Maine, and appears to be frequently taken in Texas. This com- 

 mon species is M. Guende's insii/snrici, as I learned by examination of his 

 type-specimens; it is also Mr. Grote's perslmilata, as 1 have rec(!ived, through 

 his kindness, several type-specimens. The larva I have reared on Celastrus 

 scamlens at Brunswick, Me., but, unfortunately, preserved no description of 

 the caterpillar. Mr. Belfrage has also reared it in Texas, and sent me the 

 pupiie.
