Queensland (Maranoa district). Coll. Higgins. 



This fine insect appears to be most neaily allied to, 

 although abundantly and conspicuously distinct from, 

 D. dispar ? , Newman (Penelope, Newm.). 



The specimen described is the sole exponent of the 

 species which I have yet seen, and has been handed to me 

 by Mr. Higgins for description, with the request tliat I 

 should dedicate it to the gentleman by whom it was pre- 

 sented to him, and to wdiose zeal our cabinets were origin- 

 ally indebted for numerous novelties indigenous to Queens- 

 land, a request which it therefore affords me much pleasure 

 to fulfil.
