This group has been usually placed with the Notodontidse (Ptilo- 

 dontidse). Recently Mr. Hampson removed Thaumetopcea ( Cnetho- 

 campa), placing it in the Eupterotidfe and was followed by Mr. 

 Schaus with Apatelodes, and Mr. Grote with Phalera. I shall in- 

 clude all the hairy Ptilodonts whose larvse are known, with the re- 

 mark that some of the Indian genera now included in the Ptilodon- 

 tidse will be found to belong here when their life histories are worked 

 out.
