The single example collected by Mr. Bartlett is the third known 

 of this peculiar species. The typical specimen was once in the pos- 

 session of the Society, but mysteriously disappeared. The second, 

 which was sent home by Mr. Lobb from Limabamba, Peru, formed 

 part of the collection of the late Mr. Cuming, and is now in the Bri- 

 tish Museum.
