HY n. J. CAUTEK. 483 



Five specimens have been examined, three taken by the 

 author and Mr. Duboulay at Otford, in December, 1911 

 (beaten from foliage of Acacia, or Lillipilli, in company with 

 iV. multesima Oil.), the other two taken in November, by 

 Mr. Tillyard. Mr. Cox has cut out specimens from timber 

 at Ourimbah. The species is easily recognised by its almost 

 concolorous, beautiful bronze colour, its undulate and cos- 

 tate surface, and its sublobate apex, which characters make 

 it quite distinct from all other described species. The apical 

 spines are the termination of the interior costae. The male 

 has the last segment of abdomen shorter than that of the 

 female, with its apex trvmcate, the corresponding segment of 

 the female being rounded and extended fully to the apex of 

 the elytron. Types is the author's coll.
