3. On new Genera and Species of Moths of the Family 

 GeometridcE from India^ in the Collection of H. J. Ehves. 

 By W. Warren, M.A. With Notes by H. J. Elwes, 

 F.'Z.S. 



[Received April 18, 1893.] 

 (Plates XXX.-XXXII.) 



[The following descriptions have been written by Mr. Warren, 

 from specimens selected from my Collection, Mbilst engaged in 

 working out and arranging tbe insects of the family Geometridce in 

 the British Museum. They were intended to bave been published 

 as part of a paper on the Lepidoptera of Sikkim, of which t\Ao parts 

 have already appeared ; but as the total number of species is very 

 large, and the Mhole of the Indian Heterocera are in course of 

 revision by Mr. Hampson, and as many of these species of which 

 specimens were collected by me in 1886 have remained so long 

 undescribed, I have thought it best not to delay any longer descrip- 

 tions of the new species. 



I may add that, as I have examined the whole of the large col- 

 lection formed by the late Mr. Atkinson now in the possession of 

 Dr. Staudiiiger, and as Mr. Warren has studied tbe whole of the 

 Geometrida) in the collection of te British Museum and of Mr. F. 

 Moore, there is good reason to believe that few or no syiionyms 

 will be now created. 



The notes which I have added ^^ ill give, as far as possible, the 

 localities where these species have been taken, though of many of 

 them, for which I am indebted to the late Otto Mtiller, Mr. Knyvett, 

 and Mr. Dohcrty, we know but little at present.
