tain the Htibnerian term Eustrotia, for the reason that Erastria 

 had been employed for a genus of Geometridae by Hiibner before 

 it came to be used for the present group by the Viennese Ento-

 I have not been able to examine all of them a:s carefully as I 

 wish, for of some I have only single examples which I cannot de- 

 nude. I entertain but little doubt, however, that they are all cor- 

 rectly referred to this genus. Mr. Morrison has described E. 

 marice as Hadena norma and again as Lithacodia penita. ■?-- ■■. --i .
