4th joints of the antennse is also a strong character. The antennte 

 are decidedly, though not much,, longer than the whole body. The 

 transverse impression across the disc of the pro thorax is well- 

 defined and strong. In the male the whole middle part of the 4th 

 and -Sth ventral segments is occupied by a large deep excavation 

 very like that in T. impressicollis but without the erect lateral 

 processes. The basal joint of the front tarsi is very little dilated. 



This species must be near T. viridula, Er., (from Tasmania), but 

 as the author of that species expressly states that the 3rd and 4th 

 joints of the antennae are equal I must regard the two as distinct. 

 Tasmania and S. W. Australia have so few species in common 

 that I have no doubt other differences would appear if my example 

 could be compared with Erichson's type. 



Port Lincoln. 



N. B. — A female (also from Port Lincoln) which I attribute 

 doubtfully to this species is a wider insect, with antennae scarcely 

 differing from those of the male ; its colour is coppery-aeneous with 



greenish reflections.

Yery close to T. Iceta, but seems to be distinct. It differs from 

 it as follows ; — a more or less elongate shining elevated slender 

 line runs down the middle of the clypeus ; the colour is dull or 

 brassy green rather than a bright clear green, and the general
