Mr. Newman was the first to describe this remarkable Longi- 

 corn in the Zoologist, but no figure of it has yet appeared. I 

 have seen two specimens, both taken by Mr. Horsley, at Hunter's 

 River, New South Wales ; and up to the present time it is very 

 rare in collections. The singular conformation of the antennae, 

 this organ being 12-jointed, immediately distinguishes the genus 

 from others of the Molorchidee.
