I had established this new genus for Tyrus Victoria}, King, and 

 it is very different from Tyrus, which has no representative in 

 Australia. There are several new species of these fine insects. 



A 2. Prothorax smooth, hardly punctate. 



B 2. Posterior tibia? $ with a strong ante-apical spur. 



C 2. Spur very strongly compressed; joint? of the 



antennas 8- 1 transverse in the $■ Victories, King 



C 1. Spur hardly compressed; joints of the antenna? 



8-10 square in the $■ armata, n.sp. 



B 1. Posterior tibia? without ante-apical spur, but pro- 

 vided with a strong basal tooth and another 

 median one. $ Leana, n.sp. 



A 1. Prothorax strongly punctured and even rugose. 



B 2. Joints of the antenna? 9-10 square; punctuation 



of the prothorax strong, but simple puncticollis, n.sp. 



B 1. Joints of the antenna? 9-10 transverse; punctua- 

 tion of the prothorax very strong, confluent and 

 rugose dimidiata, u.pp.
