Deficription of a new species of Ptilium, discovered htj Mr. 

 Aug. Simson, in Tasmania ; by the Rev. A. Matthews, M. A. 



The beautiful insects described in this paper were found hy 

 Mi-. Aug. Simson, of Brighton, Tasmania, already known as the 

 discoverer of Amhlyopinus Jansoni. They belong to the first 

 section of the genus Ptilivm, which has hitherto only contained 

 the rare and elegant species, Pt. angnlicoUe and Pt. Ilalidaii ; 

 from both of these the present species may be known by the 

 extraordinary sculpture of the thorax, which is traversed in 

 nearly straight lines by distinct , rows of minute rings, touching 

 each other at their sides, so as to present the appearance of 

 chains. Two specimens only were found by Mr. Simson, 

 and forwarded to Mr. Janson, who very kindly presented them 

 to me.
