Types of contacta and cUffusiUs are in the British Museum, tliougli 

 I did not see the contacta. Mr. Grote apparently did see it, and as he 

 had the type of Harvey's species his reference can be taken as correct. 

 The type of asjpera is in the Tepper collection, and is the same as dlffti- 

 silis type.
