"Valparaiso, December to February." — T. E. 

 This appears to be one of the most variable in tint and 

 outline of the Chilian Lepidoptera ; the only form which 

 shows any real difference of pattern, however, is var. 

 vuiciilosa.

The male bears considerable resemblance to the 

 Japanese Ilemevopliila suhspersata of the same authors, 

 which (by the way) is not a true IlenieropliiUi, though

 Nearest to H. emiliaria, of Australia ; pale sandy 

 yellowish, varied here and there with white, and crossed 

 by numerous parallel undulated grey-brown lines ; three

 the only prominent part of the secondaries is at tlie extremity of 

 vein 4 or 5, whicliever way yoii choose to count; that is, at the 

 third median branch. In my opinion the genus should be quoted 

 as Felder's, since Herrich-Schiiffer gives no type.
