Twelve specimens of a narrow species from Ulverstone 

 (near the original locality in Tasmania) probably belong to 

 this species ; they are somewhat variable in markings, as are 

 most species of the genus. 



Mr. Blackburn says of the type, "the suture between the 

 first and second ventral segments is extremely fine" ; this is 

 the case with my specimens across the middle (in fact in some 

 specimens the suture in the very middle seems quite obliterat- 

 ed), but at the sides it is well defined, although not so deep 

 or wide as those of the following segments. This character 

 will readily distinguish it from most species, but in this, and 

 many other characters, it strongly resembles the female of 

 ventralis. 



The prothoracic granules are traceable to a certain extent 

 through the clothing, and on abrasion are seen to be large, 

 round, and feeble ; the elytral punctures in the strige are (for
